Go juice for my saw

So I bought a new husky 562 the first part of February & purchased enough of Husqvarna’s special fuel at the same time to get the additional 2 years warranty. I’ve also ran through several additional one quart cans of the stuff. I love the way the saw runs and want to take good care of it, but $8 a quart is starting to seem a bit ridiculous. After all, one of the reasons we burn wood is to save on heating costs! Right? So my question is has/ does anyone here use the canned TruFuel? And what are your thoughts on it? Been considering going up to the local airport & gett LL100 octane av gas. Any thoughts anyone???

 

I go to a local airport and buy no lead regular octane fuel instead of the high octane for less money. I use it in all my small engines.

 

The last 2 years now the only fuel I buy for the saws and trimmer is from the airport. Just last weekend bought 4 gal for $19. Call the airport get the price per gal and figure your oil cost to mix then compare the cost.

 

I run 89 octane E free marine/rec fuel in my small equipment. If you're near a lake/marina that'll be around, otherwise av gas is great too. Try the puregas.org website.

 

Avgas smells sooooooo good.

 

I do the same, I found one station about 10 miles away that carries it, I run it in pretty much all my small engines, saws, blower, trimmer, snowblower, power wash, lawn mower and four wheeler. No issues at all.

I do have a local station that has 91 no ethanol which is what I’ve been using in my other saw for the last couple years with no issues so that’s probably what I’ll go back to. Or perhaps the airport, not sure of the price there. I bought a gallon of TRU FUEL at menards this evening for $15. Anxious to see if I can tell any difference.

 

I’v Never considered myself a cheap@$$ when it comes to running good equipment. But seriously $32 a gallons for the Husqvarna stuff ? Not willing to do that for long. I’d gladly do $5-6 at the airport. Do you think switching around will have any effect on the auto tune of the 562? I’m thinking that’s exactly what it is designed for, Sorting out the best adjustments for the conditions and fuel in play at any given moment

 

thats all i run in all my saws, weedeater, backpack and anything that sits a long time will get a dose of it occasionally.
about $5 per gallon

 

Also what mixture does everyone run? Books for both saws say 50:1. I’ve always run richer in the 345 (Maybe that’s why it’s lasted over 15 years & working harder than it was probably designed for). I’ve been adding two capfuls of mix oil to the quart of canned gas also in the new saw. I do like the smell of that stuff though

 

Just buy gas at the pump or if you want to spend extra get e free gas. There is not benefit to buying high octane gas.

 

91Efree with a amsoil saber at 45-1. If efree isn't available premium pump gas at same ratio.

 

I use pump gas until the last tank before I store something and then I use true fuel. For example if I know I will be doing alot of cutting, or weed wacking or leaf blowing its pump gas. But if I think this may be the,last time I use these tools I put tool fuel in. Just an option and I have been doing this 3 years now and no issues

 

I just get 5 gallons of 87 octane and add Stabil once a month... If the month goes by and I haven’t used it up, it goes in the car? I don’t leave gas on my small engines too long. It takes some work to keep track if I leave something with gas in it for a bit, like the snowblower during the winter, but (knock on wood) so far so good... Wish there were more options for ethanol free gas nearby. If I’m traveling and can get ethanol free at the pump, I’ll spring for the extra $0.30 per gallon but making s special trip just doesn’t seem worth it. Not at least until something breaks down and I’ll be kicking myself for not listening..

At $32 a gallon for the premixed packaged stuff, you gotta wonder what the break even time is when the fuel ends up costing more than just buying new equipment...

 

When efree wasn't in my AO that's what I did.

 

Use e-free 91 octane laced with Sea foam in all small engines. Use reg. gas for the ZTR, but mix the last 10-15 gallons before the winter with blue Sta-bil. Store everything with a full tank. No problems yet-knock on wood.

 

I buy 91 or 93 ethanol free and but the premium Stihl oil mix. Not for nothing, but at $32 per gallon, I sure hope you are not running a large saw. My MS880 is thirsty when I do use it and there is no way I could swallow that expense without anger. It would take~1.3 qts to fill the ms880.......

If it gets you the warranty I get it, or running a small saw maybe. Save the money for another hoarding tool!!!!!!!

 

I suggest that using avgas is not a great idea. It has high lead content, which is bad for you to inhale. It has much higher octane than needed for all but the hottest race saws. Octane does not increase power from a simple engine like a chainsaw.

Lead is bad for an engine. It's use requires a scavenging agent to be added to the avgas, called bromine. When burnt, the bromine becomes bromide, which is corrosive when mixed with water. Burning fuel makes water, which combines with the bromide to corrode the insides of an engine.

For this reason the oils used in aviation have to be different, they have to cope with this corrosive environment, and have to help scavenge lead. A few years ago (OK, decades) Mobil came out with a synthetic oil for aviation piston engines. It failed at scavenging the lead byproducts, and caused significant damage to many engines. It was removed from the market. Today I don't believe there are any straight synthetics formulated for aircraft piston engines, there are some semi-sythetics. I am fairly certain likewise that chainsaw oils are not formulated for dealing with lead either.

It has been demonstrated that lead causes damage to the brain. It has also been demonstrated that children living near General Aviation airports have higher lead levels in their bodies. I suspect the same will occur while operating a saw on avgas.

So, considering it is bad for you, likely bad for your engine, and adds no value (power) - why would you use it?

No agenda here, I am a pilot and mechanic, who has breathed and continues to breathe his fair share of lead. But run it in a saw? No way.

 

We use 92-93 octane pump gas and every now and then buy a gallon on the premix gas, run a tank full of it every so often. I was mixing one gallon of pump gas up at a time and using it quickly. Found a station about 20 miles from home that has 93 E free gas, so we went to 5 gal mix (Stihl Ultra, silver bottle) and get 5 gallons at the time now. Been running that in my MS362 for 4 years, no problem. Works great in my Husky trimmer too.

 

I buy 5-gallon cans of VP Racing SEF94 at my local saw shop and that will last me all year in my outdoor power equipment. For under a hundred bucks I get an "insurance policy" at least in my mind, that guarantees I have a quality fuel in my OPE. I have never had a failure of a machine since I started using the stuff, and they fire up immediately every spring after sitting for the winter. It is cheaper to buy 91 octane e-free gas at the pump and mix with full synthetic 2-stroke oil and stabilizer, but by the time you buy the gas, the oil and the stabilizer and take the time to mix it up, personally I don't find it to be that much of a bargain.
