Can You Use 40:1 in a 50:1 Chainsaw?

I bought a Stihl chainsaw.  It is 50 to 1.  My Repeat backpack blower and weedwacker are 40 to 1.  Is it ok to run the l to ane in them?

What model Stihl is it? I run xl:1 in all of my saws.

Personally I would run them all at twoscore:ane.

A picayune more oil than spec never seems to practice whatsoever harm.

The mix needed seems to depend mostly on the quality of the oil. Modernistic oils just lubricate amend, and so allow a lighter oil mix.

No, merely run the 40:ane in the saw.

Ha ha ha ,I'd run information technology on 32 to ane and then who's right ?

Al, you are a stubborn ol' cuss. Technology has come a long fashion since your 'new' 3-25.   Most engines will work best on l:one using modern oils.  Running more than oil will hateful less fuel resulting in a lean burn.

Nearly engines will piece of work best on 50:1 using modern oils.  Running more oil will mean less fuel resulting in a lean burn down.

Which brings us to another point: Whatever your mix ratio, adjust your carb for that mix.

My chainsaws all run on 50:ane, using a high quality mix oil. A weedwhacker labeled for 32:1 likewise runs on the same l:1 mix, and has for several years with no problems (one time I readjusted the carb for the new mix). Same thing for an former leafblower labeled for 40:1.

If I wasnt running 32:1 I would run twoscore:one.     Just to easy to pour 4 ounces out of the bulk bottles to mix four viii 12 xvi become the idea. Plus I feel inexpensive insurance.
50:1 to me was a epa matter to pass emissions and a mode to sale yous less for more $$$.  JMO

I'm not going to start the oil wars over again nor debate how running a heavier mix decreases the amount of oil or gas causing a lean burn .I'll but say that a majority of the race saws I've ever seen run at 32 to i mixture .I figured if these guys trust that mixture in a 5000 dollar hot saw I certainly tin can in my 200 dollar specials .Besides that fact I am an one-time fuddy duddy

Al,
the merely fourth dimension I watched hotsaws working was dorsum in the lxx's at a logger sports and those they ran for a few cuts and then they shut down and that part of the show was over and the saws were wrapped up and tucked away.
For solar day in day out apply 8-10 hours a day hard usage we used 40-1 several years dorsum but more commonly now it's l-one and the saws take held up just fine.

16 -ane is probably smashing for cookie cutters but it'south hardly existent world workaday reality.

 I can't argue on that considering it'due south a preference .Yep the oil is better but I however use good oil but just at 32 to ane considering I'thou stuborn .They don't smoke like they are burning soft coal or any matter .The screens don't plug up because there aren't any .

Nigh of the hotsaw crowd run 32 to 1 in their work saws and several are pro loggers  if that means anything .

Yous can argue about more oil leaning out the saw all you desire, only real earth results can prove anything

Oh hither nosotros go again .As signal to ponder subscribing to the theory that using more oil increases the liklihood of causing the engine run lean would and so have to assume it would be better to straight gas them . Next !

Yep the oil is better but I still use good oil just merely at 32 to 1 because I'm stuborn .Most of the hotsaw crowd run 32 to 1 in their work saws and several are pro loggers  if that means anything .

That's what I'm worried about.People non familiar with saws might recall that they need to run higher ratios of oil because they read hither that it is a better way to go even when manufactures recommend the 50-one.
In our surface area on the coast,all the falling is/was done with saws burning minimum 2 Imp gallons per day per faller 11 months a year.That'south effectually x litres per day gasoline mixed with 200 ml oil for 50-ane.Needlessly calculation a couple hundred extra mls per day for 200-300 days per year, adds up to a lot of extra money especially when a visitor is running xx+ saws.
I was a total time logger for the first thirty years of my working life and that's what I observed,if that ways annihilation

Well yeah it depends on the circumstances for sure .I too can hands burn 2 gallons a 24-hour interval.More if I run the 100 plus  cc saws .I don't exercise information technology everyday though ,apparently .

On the subject though simply inside the last hour or and so I researched this subject with extensive tests regarding several types of oils from several manufactures and the tests were very interesting .The ratios were from 20 to ane to 100 to 1 and it was surprising with consideration of the operating temperatures ,wear on the engines and other considerations during the full loaded vi hour tests .

However you'll never run a saw fully loaded for vi hours direct non stop unless you had a ii gallon fuel tank so therein lies a fallacy equally far as comparrison .

At present as far every bit ratios or type of oil I really could care less what people run in their own saws .If a person is comfortable with 50 to 1 or sky forestall 100 to i that's okey dokey with me .

Upwardly until virtually two-three  weeks ago I could accept made a broad argument I never cooked one until a little faux pas occured where I straight gassed a prime by accident and smoked a summit cease on a classic Mac which annoyed me immensely . As they say and putting it politely "things " happen for want to use much stronger words .

At present simply to even things out and to show I'yard non ane sided a little blurb almost oil in general  .

I'm a kid of the sixty'south .The Beatles,Elvis ,leather jackets ,the whole ix yards .

In those days the later 50'southward cars we drove as teenagers would go like l,000 miles before they but nigh needed a major overhaul of the engines or at to the lowest degree a valve chore .Fords ,Chevys ,didn't make a difference .

Now by the eighty's those aforementioned modest cake Chevys could go 150,000 miles before they needed attending .GM certainly didn't make them whatever better ,the oil got amend and thus it did with mix oil for 2 cycles .

Al, I'm on your side, not confronting you

And a side note about auto history, Automakers have indeed improved their engines, and the oil quality has besides improved, both going together to produce longer lasting engines.

Maybe I can run 100:ane mix in my truck'southward crankcase, crusade directly oil might cause it to run lean and seize upwardly

tyb525,

Information technology seems to me that running two to three times the amount crankcase oil in your truck would exist more to your way of thinking.If the dipstick shows total,double or triple her and she'll run forever
