I remember reading on here that one can use ATF as injector cleaner in diesels..
So as part of the usual before MOT treatment I went to purchase myself some, however the bloke behind the counter told me not to use it as "it destroys the matrix in the fuel filter in Vauxhalls". Despite my protestations that the engine is actually an Isuzu and the fuel filter used for makes other than Vauxhall I wasn't for having it.
This same guy has past form for telling me that it wasn't faulty glow plugs, they had been burned out as the car was keeping them on for upto a minute after starting (all this from simply testing them on a Multi Meter). I asked oooh shouldn't they be on after the car starts on ANY car... He said never... I asked to see the Boss (It stated on the manufacturers website that they stay on for a while to help with emissions and are thus designed for that)
As skipweasel said "I think he's a lying twisting git."
However thinking I might have been dreaming but not being stupid I declined his kind offer of 300ml of Injector Cleaner for £7.50+VAT and came home to have a chat with google
See...
