CORNHICK All-Star Author Omaha Posts:597 Points:270,505 Joined:May 2008	Message Posted: Mar 1, 2013 1:52:15 AM Ignore CORNHICK Report Abuse So I was wondering what should I do should I buy my own bottle of octane booster and dump it in with my gas that is 89 octane or just buy 91 octane for my weed trimmer it says 89 or higher. The 89 has ethanol and the 91 doesn't however it would be cheaper for me to buy the octane boost and add it my self!

So I was wondering what should I do should I buy my own bottle of octane booster and dump it in with my gas that is 89 octane or just buy 91 octane for my weed trimmer it says 89 or higher. The 89 has ethanol and the 91 doesn't however it would be cheaper for me to buy the octane boost and add it my self!

RAB2010 All-Star Author Kalamazoo Posts:506 Points:66,210 Joined:Mar 2010	Message Posted: Mar 10, 2013 2:29:27 PM Ignore RAB2010 Report Abuse No - it is not the octane, it is the ethanol. The small air-cooled engines run too hot for many ethanol mixes. This is a particular problem in the spring, when it is time to do yard work, but refineries have not changed over to their summer mixes. The engine heat causes the ethanol to vaporize, creating vapor lock. Don't waste your money on the octane booster. Buy the real gasoline. One more reason to reduce the ethanol in gasoline blends.

All_Wheelin Veteran Author Twin Cities Posts:492 Points:504,215 Joined:Mar 2011	Message Posted: Mar 8, 2013 9:49:47 PM Ignore All_Wheelin Report Abuse Ah, 2-cycle vs 4-cycle might make a difference? The mover of about 15 years is 4-cycle. The leaf blowers have all been 2-cycle. There is a station about a mile away with 91 E0 (at about .30/gal higher than the rest of the 91 in the neighborhood). I guess at a couple of gallons a year, it won't make much difference in the budget. Thanks again.

manaknight14 All-Star Author Pennsylvania Posts:538 Points:432,185 Joined:Oct 2011	Message Posted: Mar 7, 2013 9:04:42 AM Ignore manaknight14 Report Abuse If 89 octane is what's recommended, buying 89 octane with ethanol in it and then boosting it to 91 is accomplishing nothing, because the higher octane isn't going to help your mower. Buying the ethanol-free 91 might actually be worth something, because small engines can have problems with ethanol-laced gas. Double-check your manual and see if it says anything about ethanol. If it says not to use ethanol, pay the extra money to get the 91 octane pure gas (unless you can find a place that sells 89 octane without ethanol, which would be just as good). If the manual says ethanol is fine, just use your normal 89 octane and don't bother with the booster. [Edited by: manaknight14 at 3/7/2013 9:05:30 AM EST]
