The Focus (Y reg, 2001) is currently at a local garage waiting for its MoT. It's also booked in for its annual service, but because we've had to pay out for a number of things recently SWMBO, who handles the household finances, objected to this.

The car doesn't do many miles - I think it's averaged out at ~5k per year since we bought it, currently <60k - so her reasoning was that it should be ok to miss the service out. I pointed out that the last 2 services have only been 'interim' ones, as will this one, so we're already perhaps pushing our luck. I've never done DIY servicing so that's not currently an option.

So what do you think - how important is a yearly basic service on an aging low mileage vehicle? Any ammunition I can use in an argument will be gratefully received :-)
Servicing a low mileage vehicle - necessary? - ifithelps
Just changing the oil and filter might be a reasonable compromise.

Or look into the Ford dealer's cheap servicing for older cars plan.

Then you can tell SWMBO that you are not actually spending £125, but saving the extra £100 or so a full-price service would cost.

The checks on your car made for the MOT represent a fair percentage of what a service consists of.
However, no matter how many miles a car does in a year, a change of engine oil and filter is worthwhile.
Air filters become clogged up and spark plugs wear out over time so these eventually need to be replaced.
Brake fluid absorbs water over time which can lead to ABS and brake failure so this should be changed, I would say every 3 years.
MOT brake testing does not guarantee that your pads and shoes will have enough friction material on them to last a year, so these should be visually examined.
Your car, if a petrol model, has a cambelt that could break and wreck the engine, making the vehicle valueless. A garage could advise as to whether the cambelt is in need of replacement.
As you can see, annual servicing has implications for fuel economy, longevity of the car and, most importantly, safety for you and your family.
There's no need to take this 8 year old car to a Ford dealer however. Find a reputable independent garage and seek their advice on the work required.

I feel that dealers who offer relatively cheap basic servicing on older cars do so as a "loss leader". They hope to find other faults so that they can sting the owner with high costs to carry out the work required.

Hi Focus,

I get an oil and filter change from National for around £25 (cheaper booking on-line), renew the air filter and do the basic levels tests, topping up if necessary, myself.

Mmm... just rang them (couldn't bare the suspense) and doing MoT now. Problem with handbrake on one side, either caliper or cable - it's on the ramp, they're getting back to me in 15 mins...

Service was done this morning, and chap said that as it was only an interim one they wouldn't have picked up the handbrake issue. Is that reasonable?
Servicing a low mileage vehicle - necessary? - maz64
Well they've just rung to tell me I can come and collect it, so hopefully that means I can drive it back legally...
Servicing a low mileage vehicle - necessary? - maz64
When I got there, I spoke to the person who had told me on the phone about the handbrake problem. He said (IIRC) that the caliper was stuck, but they unstuck it and it appeared to be fine after that, so they left it at that - no charge. He said he can't guarantee that it won't happen again, so advised keeping an eye on it. (There's an MoT failure sheet as well as the certificate.)

Only advisory was on slight deterioration in rear exhaust.

Total price was £163.83 - top 3 items on invoice were (ex VAT)
MOT test: 54
labour (1 hr): 45
engine oil: 21

The 'industry standard service' tick sheet looks quite impressive - 50 boxes, all either ticked or marked N/A. I can give more details if anyone is interested.

I'm pretty satisfied - it can be viewed as expensive, but I haven't been charged for any extra work, and the people I've spoken to have been polite and honest as far as I can tell.

Thanks - although it was a bit galling coming in on the train this morning to spot a garage near one of the stations advertising 'MoT+service' for £99. But like I said I think the service I got was a bit more than basic, and there weren't any extras.

Just an update on MoT City, mainly for Alanovich.

Stepson has just got his (ie. our old) Yaris MoTed plus full service. The car is over 7 years old, and is red apart from the matt black bonnet which he fitted himself after a prang (along with various other bits and pieces):
www.honestjohn.co.uk/forum/post/index.htm?t=70116&...f

He dropped it off at 8am, and got a call at 9 to warn him that it would need 3 new tyres for starters...

Well it came to about £400 all in, including £120 for the 3 tyres (which he was anticipating), 2 hours labour for the full service, and the MoT. They had one or 2 advisories, but apart from the tyres, no failures - just a couple of advisories. Stepson says it feels a lot better to drive now.

So the recommendation still stands.

Thanks, Focus. I'm interested as my (Jan) 2006 Mazda 6 is due its annual mot and service in January, and I'm trying to plan ahead what I want to do with it. It's only on 31000 miles, having covered only 5,000 or so since its last, full Main Dealer service in February this year. The warranty I bought with it will expire in February, and I won't be renewing it. I think I might just go with an oil change service, as it seems to me the car is perfectly OK otherwise. At 4 years old I think it's time to go Indie, I'll be giving MOT City a call shortly for a price. Thanks again.

>>A garage could advise as to whether the cambelt is in need of replacement.>>

To check that out on my car, they would have to take it apart in any case to do the check. Most likely go on mileage, which you can work out for yourself...:-)

***Always*** get the oil changed at least once a year, in fact engine oil deteriorates faster on short runs.
Personally, I would only use a top notch engine oil in my car - engine oil = lifeblood!
Cam belts? well - there is a swear filter in use ... a neglected cam belt replacement often causes much pain - of the financial kind!!
Servicing a low mileage vehicle - necessary? - jacks
If a car is over 3 years old the annual MOT check - done correctly - will duplicate many of the important checks carried out in a service but the oil change is a must as you are covering such a low mileage presumably with many short runs.

I don't see the point of paying a main dealer £90 an hour to check such things as washer fluid, lights, seat belt tensions etc - so I take a piecemeal approach.

On my wife's 6 year old MINI (bought new and serviced up to 50K under the inclusive service package as part of the cost when purchased).

since 50,000:

1. Take car for annual MOT at local trusted independent
(I rely on this check for steering suspension corrosian etc)

2. Ask MOT tester to check pad thickness whilst the car is on the ramp

3. If all ok - drive home, change oil and filters(3) myself, check battery, fluid levels, grease hinges etc

4. Periodic items not covered above (coolant/brake fliud/gearbox oil change, polybelt replacement) I get a price for that job only from the indy and get it done as per the book.

Advantages - cheaper, only pay for what is required.

Disadvantages - the "book" is not stamped, which may be a problem for some but I keep all receipts and a documented record of what's been done AND we're not planning to sell, we'' probably keep it for a few more years and then pass on to one of my sons.
I realise the missing stamp may an issue for some.
Note: If you can't do the oil yourself - kwikfit will do it for £35 using Mobil 1.

Whyever not? It won't be a franchise stamp, but any respectable indie's stamp is better than a blank space.

I ran a 306 HDi for 6½ years and changed my own oil and filters throughout - handwritten record every 6K. When the car was traded in at a Pug dealer, one of their mechanics kept the car for himself, commenting that the service record was better than most of their cars'. (It had my indie's stamp for brake fluid and cambelt changes as well).

Some makes/models recommend spark plugs changes at 100k miles, and air-filter changes at the major service.

You have greater chance of ruining the pump if you cannot be sure that the fluid change has been done in near-perfect "surgically-clean" factory conditions.

Servicing a low mileage vehicle - necessary? - Rattle
As stated brake fluid absorbs water so over the years use loose their properties. I usualty tend to get it done every two years but often with my dads car its needed major brake work requiring new fluid anyway within that time.

As for servcing I did a full service when I bought the car including new plugs (there is no HT leads on my car). Its still on the original coil pack so that might go but fot the next service which is due the same time as the MOT I will simply have an oil change done and change the air filter myself.

I do a mini service every month anyway which basicialy consists of a tyre, light and fluid check.

Every 6 months I will jack the car up and check for play in bearings etc.

Don't skimp on servicing but it dosn't mean you need to pay £100 for a service. I will also get the camshaft bolts checked sometime as they can work loose on my car.

I think the semi DIY approach to servicing is knowing what to look for and what common faults go wrong with a certain type of car. You can then use a trusted garage just to do certain jobs such as an oil change or even plugs if you're scared of cross threading them.

I find sites like this help a lot in terms of diagnostics that is where I save a fortune. I get my mechanic to tell me the code, then I work out with the help of others what is really going on and its often not what the fault code tells you.

I will never forget driving my Triumph Herald down a welsh mountain with no brakes due to water in the (never changed) brake fluid boiling and leading to a loss of hydraulics.
Nowadays, water in the brake fluid causes corrosion in the ABS systems.
Engine oil deteriorates within the engine despite the mileage, in fact short journeys are harder on the oil.
The OP is not car savvy so needs some advice as to when various consumables need to be replaced.
I've known a few folk who believe in the "my car never needs servicing" creed but these people almost always get rid of their motors at 3 years at the most so they get away with it.

The car with the most worn out engine that I've looked at was a 13 year old Fiesta. I know that it had covered a genuine 43,000 miles, because it was always owned by relatives. It had had a diet of very short journeys.

Cars which always make short trips and never get warmed up properly do wear their engines out. One way of trying to prevent this is to change the oil at least once a year. It probably more important in low mileage cars than ones which live on the motorway.

...Have the fluid changed at maker's intervals, but not because of some unproven "water" in fluid theories....

I've been in an E-type Jag which had been stood a while and then taken for a blast.

The brakes failed and when we stopped, you could see steam coming from the fluid reservoir.

To me, the fluid had boiled and there was no doubt the brakes had failed.

I seem to recall it used to say 'Don't expose to moisture', or something similar, on containers of brake fluid.

Ford say change the fluid every two years, which is probably a bit over-cautious.

I think I had the same fluid in the last Focus for thee or four years with no noticeable drop in braking performance.
Servicing a low mileage vehicle - necessary? - Number_Cruncher
While I don't deny the water in brake fluid theory completely, I think that on modern cars, the concentration of copper ions in the fluid is also a compelling reason to change fluid regularly - to prevent the deposition of this copper in the close clearances between the working parts of the ABS unit.

>>The brakes failed and when we stopped, you could see steam coming from the fluid reservoir.

In all probability, one of the brakes had siezed up. All brake fluid boild at some temperature or other, and it's entirely probable that you saw very little "steam", and instead saw the brake fluid condensing as it hit the cool outside air.

>>no noticeable drop in braking performance.

Unless you routinely run your braking system up to the fluid's boiling point, you would not expect to notice any difference in braking performance.

Yes, but how is it going to absorb water when it's in a sealed system?

As long as the cap remains closed and there are no leaks in the pipes or seals, how will the fluid come into contact with water?

Personally, I suspect yet another money making scam on the part of dealers to convince us that the brake fluid must be changed bi-annually for safety reasons, when that simply isn't true.
Servicing a low mileage vehicle - necessary? - bathtub tom
It's not a sealed system.

There has to be a small hole in the filler cap to allow air to replace the fluid as it drops due to the braking material wearing (disc caliper pistons will sit further out in particular).

Air contains water vapour.

There will also be an air movement in and out of the reservoir as temperature changes cause parts to expand and contract.

OK, that makes sense. But how much of an effect does this have, in say 2 years or 4 years or more? We're talking about a very small influx of air over a considerable period of time, with only trace amounts of water vapour in it.

That's where I think we might be being led up the garden path...

Some DOT3 and DOT4 products claim it's necessary to change the fluid every year! I mean, really - if it was that crucial, wouldn't those of us who never change the fluid be struggling to stop at all. ;)

I'd love to see some genuine tests of how much water DOT4 absorbs per annum in a typical car and how much braking performance is actually affected. Strangely, the manufacturers of the stuff don't seem to provide that kind of data.

I remember changing the fluid on my Kawasaki ZZR600 a couple of years ago, and was amazed at the state of the stuff coming out. A ruddy brown colour with visible "bits" floating in it. The level is checked using a sight glass on the (black painted metal) master cylinder reservoir, and actually the new fluid requires a careful look at the glass because it's so clear (champagne colour). The old stuff was so dirty you could see the level from several feet away.

Transformed the brakes, too.
Servicing a low mileage vehicle - necessary? - Andrew-T
We're talking about a very small influx of air over a considerable period of time, with only trace amounts of water vapour in it.


On most cars the brake reservoir is in the engine compartment, so the temp rises and falls regularly over quite a range during those years while the fluid is not changed. The expansion of the reservoir will be different from that of the fluid. So there is quite a large cumulative flow of (damp) air through that small hole in the cap.
Servicing a low mileage vehicle - necessary? - TheOilBurner
How damp is it likely to be in a hot engine bay?

I mean, it's all well and good talking about how much water vapour may or may not be getting into the reservoir, but (I ask again) has anybody done any actual studies on this to see how much the fluid actually deteriorates over time and use?

What really constitutes a good change interval for brake fluid? I don't doubt it will need changing at some point, but I'm very suspicious that 2 years is way too often and highly convenient with dealers trying to raise more money on routine servicing now general service intervals have increased so much and cars are so much more reliable...

Reading this thread with interest and noticed no one has mentioned aircon.

My car has just turned five years old and at the MOT done by a Volvo specialist I asked him to do an aircon service too (basically a regas). I had noticed the cold air didn't quite have that cold bite to it. It was down 25%. I plan to have the system regassed every three to four years.

Anyone out there have any thoughts on this part of the car or is it a case of if it ain't broke don't fix it system ?

I've only ever had an air con regas done once, and that was on our old Scenic when it stopped blowing cold air completely. I entrusted this to Kwik Fit who did a stellar job for the bargain price of £45. I realised then how bad the system had been for some time. The air coming from the vents was like ice, and remained so for the rest of our ownership.

I have just moved my 5+ year old 307 on, it has been dealer serviced once a year without the a/c being touched SFAIK and when it left me it was blowing as cold as it did on day 1. Maybe I was lucky? I left a/c selected all the time BTW.

Like the fridge/freezer - y'all leave that on all the time but ... swings & roundabouts is wot I say, leaving the AC on for 5 years doesn't come without cost!
