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!

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.

I would use non-ethanol gas if possible. In my area, marinas sell it for outboard motors.

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.

Maybe this explains why I've gone through a couple of leaf blower engines in the same time my lawn mower is still going strong. Gonna be looking for ethanol free options (if spring ever gets here...).

ok thanks everyone Ill just buy the 91 because Echo came out just this last year and said that it is ok to use ethanol however they won't warranty the use of it so basically they are saying to use the good gas without the ethanol.

I'm not sure what you are expecting the octane boost to do? It's octane boost, not ethanol remover.

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.

Look in the owner's manual or the company websites to get the right gasoline for your lawn equipment.

it is a Echo brand weed trimmer approx. 2010 model weed trimmer it says 89 or higher so should I just use premium to avoid the ethanol in the 89?

What does the owners manual say about gas grades? I've never used anything but E10 regular in my snowblowers and lawn mowers. NO engine problems ever.

I was told by a company that repairs lawn equipment to use mid grade in mowers. This company does not sell gasoline.

I know of no small engine that requires above 87 octane in it, and they need below 10 per cent ethanol content.

buy the sta-bil, it will keep the ethanol from causing condensation and building corrosion in you weed eater
