What oil is best? and what ratio?

[mdavlee]

(Anytime) you run a saw, I.e. Continue to run, knowing in your head (e.g. ear) that it is running lean, you are dancing with the devil....

That was the first of the belray h1r I used. Never dreamed the rpm would go up 1500 rpm almost and 2 turns out on the H to get back to 14k. Saw ran perfect on klotz and would tune down to a better 13.5k. I had made maybe 3 cuts with it when that happened cutting cookies. If I had tached it or just held it wot out of wood longer I would have heard it.

It's not a coincidence that most of the highest rated air cooled oils are blends if mineral oil and PIB.

PIB= ?? Try this, if you missed it... can be an interesting read....

(Not sure I ever hit post, but typed it at least once) short version is, "at what temp/ time, does an oil change from a lube to a goo, or a glue/ sludge?"

Keith knows I was joking. I only use 800 off-road in all my saws, ported and stock, with zero issues. The Logger that uses Safe Guard oil says he's found out that it's the QUANTITY of oil not the TYPE of oil that counts. He's also used Lucas synthetic and husky synthetic oil but didn't notice any improvement in the life (longevity) of his saws. I doubt if anyone reading this thread has ever experienced an engine failure using a 32:1 mix with ANY brand of oil. If so, I'd like to hear about it.

i have experienced bearing failure in low speed 2 strokes and they were run at 32:1. but it isn't the result of oil if is from over speed.

Im willing to bet that even the amount of engine failures running 50:1 is VERY low in normal conditions. And most of those failures being from bad fuel.

I agree. But the key is "normal" conditions. IMO 50:1 doesn't leave enough fudge factor for anything outside normal conditions.

So many benefits to running 40:1. Even if your paying say $15 for a quart of 2t oil. It only costs .35 cents more per gallon mixed, to run 40:1. Heck run 45:1 (at least you get 10% more oil than 50:1) cost ya an extra .17 cents per gallon.

Me personally, yeah I'll pay an extra .25-.35 cents whatever for a little added insurance, a faster saw, cooler running saw.

- the only reason I am testing, is to find the best PERFORMER...racing...if there even is one.

Im liking the sound of 25to1 or 20to1

 

[KenJax Tree]

For milling? IMO thats way too much for just cutting wood.

Maybe I'm wrong. I don't run a saw much anymore[emoji4]

 

[jake wells]

I got to stay at 32:1 for some of my stuff because of the fixed carburetors.

 

[Keith Gandy]

20to1 on my 241c cut with very good torque. As fast? Dont know but fast enough. We will see how mtronics likes r2 and 20to1 here in a few days

 

[jake wells]

and when i say fixed carburetor i mean this

One Logger I know said when he increased his mix ratio, Safe Guard 2-cycle..cheap stuff w/87 octane, from 50:1 to 32:1 it doubled the life of his 372's (av. 1.5 years to about 4 yrs.). That's coming from a Logger that his crew uses 372's on a daily basis in all kinds of conditions.

I would think most of the folks that use their equipment professionally as in logging just want it to run and cheap as possible and never see it internally and could care less. Its a tool and needs to work is all that matters probably

 

[jake wells]

nothing wrong with cheap oil i ran it for years with hiccup using bad gas is going to cause more problems through.

 

[TJ the Chainsaw Mechanic]

I run the Stihl oil in my Stihl. lol 50:1.

That Logger told me another Logger told him about adding more oil to his mix to make his saws last longer. The other Logger mixes 25:1. That proved to me more oil helps. Plus they use their saws more in one to two weeks than we use in a year probably.

I wonder if using more oil, like 8 ozs. (16:1), would increase the life of your saw even more?

 

[Ron660]

We will find out soon when I pull this 241 down after running several more tanks of 20to1 what more or less oil will do on the piston top and bottomend

20:1 = 6.4 ozs. Sounds good to me.

I would think it would be a blubbering sounding turd .

If you have time compare 32:1 to 20:1 with some timed cuts to see if the extra oil is hurting performance.

Get a small screw driver and turn it clockwise.
