I use Valvolene oil in my engines
You said Matt that you are using Street Machine by Pennzoil. If you read on the bottle it says that it is designed for Big Bored Out Street Machines though. That would put it in the same class as The New Castrol Edge 25W/50 (Originally Formula R and then originally GP50) Nulon 25W/60 Street & Track, etc. etc. and all of them say It is formulated with the needs of the enthusiast in mind. It is designed specifically to provide optimum film strength and protection for large 6 and 8 cylinder engines operating under high stress conditions
Will these oils still be fine for the 16v 1.6l 4 cyclinder though?
Cheers
