View Full Version : What petrol for big old engine?
What petrol should I be putting in a 1986 3litre 6cyl Opel Monza? Will it be best on normal unleaded, I feel Optimax would be wasted on it?
Cheers

If it's 86, make sure it runs on unleaded first.

Yeah, I'll give the guy I got it from a call.... it must do, too hard to get leaded these days - I'm sure it'll have been converted.
Yep, has been converted to unleaded - he's always just put 95 ron in - any benefit to me using optimax etc?

Maybe use it once or twice just for the cleaners in it then back to 95 :)
