More Tales Of Inept Spannerage..

ATF's got soap in it for cleaning the inside of gearboxes hasn't it? I'd be fairly sure that a Diesel engine wouldn't mind a glug or 2 of it, I've even heard it recommended, but I'd never heard of running it through a petrol engine.

Bah, it's only French. Just go for it young Pete, and report back your findings.

Not a good idea for my wallte in the long rung, I should mention.

I'd use a fairly high dosage of some proper injection cleaner additive like Forte instead. And unless the tank's almost empty, drain it. The petrol in there is unlikely to be any good and _will_ make things worse.

I have - some people recommend soaking a rotary engine's combustion chambers in the stuff if the engine has stood around for a while. Supposedly this softens the carbon deposits. Then you crank the engine after soaking it for a week or two, and once "stuff" stops coming out of the plug holes, you put the plugs back in and fire it up.

About two weeks later your neighbours may be able to see the sun again...

Pete M gurgled happily, sounding much like they were saying:

I'm glad there was an "m" on the front of that...

TBH, I'd just drain the tank as best as possible, and shove new fuel in. I've not had to do anything with injection that's been sat that long, admittedly, but the worst that'll happen is that the injectors are bunged up.

I took the pipe off the outlet of the fuel pump and pumped it all out of the tank. It wasn't that nice 'petrol' colour.

I wonder if the fuel in the lines has turned to jelly yet. Seen that on more than a few barn finds.

ATF in your oil is a fairly common thing done by the ClubGTI bods as a sort of pikey engine flush, just before an oil change. F*ck knows if it's a good idea in a petrol tank, but I would guess not...

A mix of petrol and 15-20% E85 would be better. The alcohol content will absorb any water and kill any slime that likes to live in petrol/water interface.

Mechanical injectors. Gotta love 'em.
