• Renault K7M - Oil Degradation 27 Jan 2012 (Forum)
  But the valve train is becoming noisy again which makes me think that the lubrication is becoming marginal at the top end (it's a 2 valver so the cam lobes are quite highly loaded) I don't want to do an unnecessary oil change if the oil is still decent. Does anyone know any other tricks for finding coolant lurking in oil?  
• Nissan X-Trail (2001 - 2007) - 04 2.2 Intercooler/diesel oil 25 Jan 2012 (Forum)
  Went to buy oil yesterday - usually have fully synthetic 5/40, but checked the garage receipt to discover they had refilled with 10/30 - semi synthetic. Questions: Will this oil damage the engine? The Uniparts store I bought oil from said I could not top up with the normal oil - is this right?
• Mk IV Golf Oil Loss 12 Jan 2007 (Forum)
  Carrying in from this topic http://tinyurl.com/yzelr3 My SIL has a 2003 1.4 Match. Is this the same engine as the FSI? She is losing a lot of oil, I don't know specific quantities, but it is not what I would call a normal amount on a low milage three year old car. When she first took in to the dealer they said they had changed the 'oil filler cap', as it was faulty.
• Filthy oil in 12 miles 14 Jan 2006 (Forum)
  One year old 8000 miles No service warning but did not like going over 1 year so had a service. VW 506.01 oil. After 12 miles checked dip stick. Oil is black. Not tinged black but black. Got the oil can in the boot -they had used 4.5 litres approx.out of it but maybe not in my car. Have a horrible feeling someone thought --this car has miles to go before the oil is done for so how about not changing it.

  I have read a lot of bad press on the PSA 1.2 petrol engine, how much of this is actual and does it cover the turbo and non turbo engines?
• 2002 1.2 16v Corsa - oil problem 18 Sep 2014 (Forum)
  After half an hour, start up tin of nails again then drive 200 yards to petrol station, put a tenner of petrol in, start up......absolutely perfect and perfect after a 3 mile drive home other than oil light flicking on n off at idle. Not the first time it's happened like this. When I first changed the oil filter after buying the car there was a fair amount of oil that came out of the filter housing.

• 1986 Daihatsu Skywing ( Like 3-cyl Charade) - Got some dirt in my engine 17 Sep 2012 (Forum)
  I'm thinking I might just do a DIY engine flush to remove as much of the silt as I can. The basic idea is to use 3 changes of 30% 2-stroke as a flush while turning the non-firing engine over with the plugs out, then, after changing the oil filter, do a couple of close-succession changes (say 100 miles or so) with Delvac 15W/40 and (very old) Mobil Special 20W/50, before resuming normal oil change intervals.

• Cam Belt changes. 28 Aug 2004 (Forum)
  I have been reading the thread regarding oil change intervals and one or two contributors mentioned cambelts. I am not sure what the manufacturer recommends (if anything) for my car so perhaps I could have a reasonably definative opinion from the techies amongst us.
• BMW longlife oil 23 Jun 2005 (Forum)
  Finally, I'm sure I've seen HJ write about 5k oil changes etc - does that still hold true with modern oils and engines? Many Thanks in anticipation! Graham.
