Skeeve Posted July 4, 2008 Share Posted July 4, 2008 91 is too low grade.You'll hear many ...things Use an octane booster Don't forget, U.S. pump gas has (MON+RON)/2 octane ratings, so our 91 is closer to the European 93 or 94 [AFAIK, most gas in Europe is quoted w/ just the RON octane #, which is always higher than MON.] Dunno about Canada, but given the track record of adopting a lot of U.S. standards since we're their biggest trading partner, it wouldn't surprise me if the gas up north of 44 is quoted w/ #s similar to ours. OTOH, given their justifiable desire to not be seen as "U.S.A.'s kid brother" they may do it the Euro method. Best advice: read the pump, & see if it's marked "RON" or w/ the formula above. Worst case scenario, you can always go to the airport & snake some 100LL; an eyedropper full of that in each tank will do you fine (as long as you don't have mufflers w/ the cat.)

Guest Petev11 Posted July 5, 2008 Share Posted July 5, 2008 i was wondering because i had to run regular for a tank full, because they had no premium or octaine boost. will this have damaged the engine? and how much octaine do i put with a 25 litre tank full Link to comment Share on other sites More sharing options...
gstallons Posted July 5, 2008 Share Posted July 5, 2008 If you do NOT experience or hear "pinging" or spark knock you will not have trouble. You can refill the tank as soon as possible to dilute the regular fuel. Link to comment Share on other sites More sharing options...

Thanks for the extra acreage, but I'm not sure that we really want most of Washington, Idaho, Montana, North Dakota, and Minnesota! Link to comment Share on other sites More sharing options...
Skeeve Posted July 5, 2008 Share Posted July 5, 2008 i was wondering because i had to run regular for a tank full, because they had no premium or octaine boost. will this have damaged the engine? and how much octaine do i put with a 25 litre tank full 25 litres? That's over 6 gallons! You certain about that #, or was that station in the middle of nowhere not only selling you bad gas but fiddling their pumps to show more delivered than will actually fit?...

Skeeve Posted July 5, 2008 Share Posted July 5, 2008 Thanks for the extra acreage, but I'm not sure that we really want most of Washington, Idaho, Montana, North Dakota, and Minnesota! Well, I should have said "44deg40' ", but I didn't want to try finding the little "o" degree symbol & figured everyone would know what I meant. What's the major portion of one degree between friends?
