also one thing not mentioned, is fuel quality, a couple of blokes at work are running that shit E10, their cars are rattling there heads off and way down on power, do people not realise that these old cars are designed to run on plus 96 octane. the amount of damage that E10 does to heads,valves, piston and fuel systems is unbelievable. i always run my WB on atleast 95 octane.
