"guyz till now i was using normal petrol from a company owned BP outlet for my 97' M800 carburetor version. but somehow i feel that it could perform better if i fill in Power or speed premium petrols..\r\n\r\nwhat do u all think? any M800 owners using these fuels? what difference have you all felt.\r\n\r\ni was going through some blogs, and i found out that if your car or bike has a high compression ratio, it is advisable to use premium(speed/power) petrols. it reduces knocking and pre ignition. and i also can across some blogs where peopla mentioned that unless n until your car or bike is a MPFI engine, these petrols wont do any good.\r\n\r\nnow my confusion is that does the octane rating of premium fuels depend on compression ratios, or does it depend on the type of engine (carb or mpfi) or both??\r\n\r\nand BTW, my fuel leaking problem has been solved.."
