Re: Oh dear, got a petrol engine - i filled up with deisal!!! help!
Lol, I'm not sure about the actual chemistry (I only did physics at a-level) but they do add a boat load of lubricants to modern diesel mixes, and to a certain extent diesel is a better lubricator (thats why the other way round is very bad - petrol in the diesel engine can dry out a lot of components in a couple of mins! Seize the engine driven fuel pump = good bye engine.)
But the lubricants are why the plugs and, actually, injectors as well should be checked as they can clog. The plugs also because the diesel won't burn that efficiently (needs higher compression that a petrol engine provides) further clogging them and subsequently the cat.
(Someone please correct anything I'm saying wrong, I'm most definitely not an expert!)
