What to mix with petrol to guarantee engine death?

[dingg]

a colleague added grinding paste to his ex wifes engine via the oil cap, ended up travelling about 15 miles before it gave up..

the muppets back with her now lol

Dissolve some polystyrene granules in the petrol.

If you get it just right, when it hits the cylinders and is ignited, it will set like concrete and grenade the engine in no time at all.

...the above may or may not be true, and should not be used on anyone you wish to remain friends with...

If someone was regularly stealing from me, they would be ending up in hospital, not at a garage.

I would have thought that battery acid may have 'interesting' effects?

How about something that would make it really go with a bang. Shirly some kind of nitrogen based fertiliser would do it. I'd suggest pouring nitrous oxide in there....but as I just worked out it's a gas that might be tricky.

Nitroglycerine

it's the only way to be sure.

Styrofoam turns petrol into NAPALM!

DOT 5 (silicon) brake fluid. It will attack seals (which is why so many people buggered up their old car's brake systems. It will also smoke beautifully and lose power. Acetone could be interesting too!

ETA

Iron filings, volcanic dust, water.

Or see if you can get some very low octane (less than 90) petrol, or some specialists still sell leaded petrol, that'll kill their Cats!!

Silicon in the fuel system will also trash the lambda sensors (aka what tesco's fuel did). If the boats dont have cats, there will be no ill-effects.

what would the cat be called on a boat?

[Poledriver]

Drowned?

sugar just plugs things up bleach would work the best but mt.dew works real good a can of radiator stop leak called mend tight mixed in fuel works super or just mix one mr. gasket head gasket sealer in to fuel any kind of paint remover not thinner good luck with your fuel thief's
