harryharls Posted June 7, 2019 Report Share Posted June 7, 2019 I hadn't even considered petrol type for my Beta Evo! I think I've just always used regular unleaded (95), should I be using super (97)? Quote Link to comment Share on other sites More sharing options...
totty79 Posted June 7, 2019 Report Share Posted June 7, 2019 Depends on engine size, the 250 is very low compression and doesn't need super, in compression order it's 250, 300, 200, 125. Quote Link to comment Share on other sites More sharing options...
harryharls Posted June 7, 2019 Report Share Posted June 7, 2019 Interesting, mine is a 250 but I wonder if it would be better for the bike/engine to use super? Quote Link to comment Share on other sites More sharing options...
trapezeartist Posted June 7, 2019 Report Share Posted June 7, 2019 Super costs about 15p per litre more. And you use 1.5 to 2 litres in a trial. I just throw in the Super to play safe even though it’s probably not needed. 1 Quote Link to comment Share on other sites More sharing options...
totty79 Posted June 8, 2019 Report Share Posted June 8, 2019 Any difference will in health or running will be immeasurable on the 250, it's compression is seriously low. It's a case of use super if you fell better for doing it, don't if you don't. I would use super on a 125 or 200, I'd try both in a 300.
