Re: fuel

If you use too low of an octane fuel for example 95ron unleaded in these engines especially jap imports, cause they are designed to run on 100ron in japan you can get Detonation and it can wreck your engine have a look at this link will tell you exactly and in detail plus for an example a jap import car runs 100ron in Japan if you put 95ron over here into it the knock sensor wont be able to retard the timing enough and detonation can happen and blow engine eventuallyDetonation Explained

To be a bit technical about it and might explain it a bit easier the piston in the cyclinder reaches TDC =Top Dead Centre thats the highest the piston can travel then you have your spark and it forces the piston down when Detonation happens for example low octane fuel when the piston is trying to reach TDC to the highest point in the cyclinder spark plug sparks at that moment so the piston could only be half way up the cyclinder and it sparks trying to force the piston back down while the crankshaft is forcing the piston up with this stress it under it will fcuk up the main and big end bearings and the crown of the pistons and can even damage the piston rings hope that explains it better
