well, i was testing out some engine cleaning stuff, and it was going ok, so i started it up to warm the engine up to dry it off, and it started quite lumpy, so i thought i had some water in the plug wells, so i let it run at about 2-4000 revs, on and off, and it got lumpier and worse until it stalled on tickover, so i looked around the engine bay to see if i got some wet i shouldnt have done, and randomly checked the oil filler cap, and theres mayo under there
never mind, it was suspected anyway, so its not the end of the world! just a shame winters creeping in
