We're going out to the track tomorrow. The pumps at the track have Sunoco stuff. The lowest is regular 94octane pump gas w/ Ethanol.
Normally, I'd run MS93, but all I could find locally on short notice is MS103. Is there anything special I need to do with it? Usual premix is 3oz of oil (Motul 800) for each gallon. Should I increase it for the 103?
Do I need to change the jetting?
Sorry for all the n00b questions, but...I'm a n00b to this stuff.
TIA. |

Same oil mixture will be fine. You'll probably need to go a bit richer on the jet with the 103 vs the MS93, but it isn't likely to be a huge change in jetting.
