OK - it's time to ask the experts!!! - scruffythedog118
I own a VW Passat 1.9 TDI (2000 W) and use REDEX all the time, and my brother-in-law has a mondeo TD and he has just started using, with no ill-effects as yet a product from a company called GREASED LIGHTNING he has given me a leaflet showing the "Fuel system treatment" suitable for petrol and diesel cars??? - this worries me a little, wouldn't it be better if something was specially for a diesel engine? Also instant engine treatment which claims to quieten it down ??

I would appreciate some expert advise from others who may have used or consider using (like me) these products,

To assist the website is www.greasedlightning.co.uk

cheers

"he has just started using, with no ill-effects as yet"

and presumably no obvious beneficial effects either ???

Aren't these fuel additives all just "snake oil"...

As a constant user of VW snake oil (part no. G 001 700 03) in all of my cars, I know it works. As if more evidence were needed, I gave a bottle to a friend with an under-used BMW 635csi and only yesterday did he report a remarkable immediate improvement in starting and smoothness of running: it is counteracting the nasty effects of his using the car for little more than six-mile trips to the railway station and back. That's exactly what I experienced originally with my Audi 100, which was also clogging up because of short-trip usage: for instance, starting changed to one feather-touch of the key and never deteriorated.

Sadly, the price of the stuff has rocketed by over 50% in the past few years, but it's still worth it at about £6.00, which gives you enough to add to 150 litres of petrol. VW/Audi dealers are woefully ignorant of it (several of them tried for years to cure my Audi's cool-running problems without thinking of using it) and probably won't have it in stock, so call them in advance if you want to buy some.

Most of those fuel additives I have seen look suspiciously similar to auto transmission fluid which my uncle (a factory-trained diesel mechanic for the past 35 years) would happily pour into the fuel tanks of his fuel-injected cars. Diesel or petrol, it didn't matter as my petrol engined car got a good doseage despite my nervous objections. He claimed it lubricated the injectors. Whether it did or didn't, I have no clue, but the car never suffered for it.

I suppose I shouldn't be surprised by his actions as his brother (my father) would occasionally pour a trickle of water into the carburettor of an engine at fast tickover..to "steam clean the valves and combustion chamber" you see.

I have always followed H.J`s. advice and used quality fuel, (Shell Optimax Diesel), which I assumed included the necessary detergents and fuel pump lubricants.

Is H.J. now saying that Millers additive is now required with a quality fuel or just to supplement the inferior supermarket grades ????

Doesn't the 'detergent' wash away the 'lubricity improver'?

And the cetane booster makes it feel like you're getting something for your money in terms of extra performance.
