661 Oil Test 32:1 vs 40:1 vs 50:1 ?

[KG441c]

Let me put this in perspective. A factory built 125cc dirt bike makes more than 40 HP. What does a 3120XP make? Only 8.4HP. An 80cc dirt bike makes 20-25 HP. A ported 461 only makes 8 HP. The power output of a chainsaw, even ported, is quite low. The limiting factory is space. These other engines are water cooled, have reed induction, way more advanced porting, and a tuned pipe. All of these are huge factors that a chainsaw simply doesn't have.

What about rpm and temp from one to the other?

Can we agree that if you pick a quality brand synthetic weather Stihl or Motul and mix at 32:1 in a ported saw that the oil will do it's job?

I think the answer is yes. A little carbon and small loss of HP isn't the end all I think? Maxima K2 is one of my favorite oils.

With 927 though I do wonder if 40:1 would be an idea since it has left a few saws with some ugly crowns. I ran a few gallons of 927
last summer and it did alright by me but after that one pic of that stock 362 piston I'm kind of sketched by it lol

Again maybe it is stock vs ported that contributed to the 927 discussion

I know I'm sounding like I'm not interested in finding the holy grail of oils. Not the case at all. I'm simply trying to put this in perspective. We are enthusiasts. You're going to get that here. We want the most we can get out of our saws, and we want to provide them with the best protection we can, even if we don't need it, lol. There is a point where better isn't better. Beyond a certain point, there is no real gain. We, I, enjoy this stuff, including the oil discussions. It's all part of the addiction, errr obsession, errr hobby

If I'm not mistaken, a 125 dirtbike will turn something like 13K RPMs. Don't quote me on that though.

These very best oils are super critical in the likes of kart racing. They're making insane HP and turning something like 20K RPMs. That's when you REALLY need these oils!

I look at it like protection from double condoms!! Necessary? No!! But probably would make me feel better protected!! Lol!!!

Double the protection and make the fun last longer..?

Absolutely!

You guys should ask him to test astroglide and ky jelly cuz anybody that pays $50 a gallon for 2 stroke oil is taking it in the a$$

Now that was funny, lol. I've even been trying to find a way to import some Mobil 1 2T Racing oil. Do I need it? Nope! But I WANT it It has more protection than I will ever need in a chainsaw, and is said to be the cleanest burning of them all. I like the sounds of that!

Redbulls test of faster times with leaner ratios didnt suprise me but I dont feel comfortable at 45to1 or 50to1 in my ported saws

 

[KG441c]

I just ordered a quart of r50!! I feel better!!!

I'm gonna stick to my cheap stuff til one of mine blows up. My 1997 ts400 concrete saw has probably 1000 hours on it. A lot of that is 5-8 hours at a time cutting driveways wot minus fill ups. Just re ringed this year. I just can't justify the added cost, as minimal as it is. I have Yamaha and still local to me. When one burns up I'm going Yamaha the

You've gotta be close. When we were kids, a 250r's shift point was 10,800. 125 today has to be 13k. I bet a kx65 is 15k.

I might point out that Yamaha 2R is commonly used in these applications..

I would go in with you on a few cases.

I believe you are way off on that. A saw is high stress imo especially milling and cutting bigwood non stop and noodling

Its really not.

I'll just keep using my cheap stuff...

That's cheap **** even by my standards!!
As long as it's blue you should be ok though...
Lol...

And some report viscosity breakdown in those applications. In some ceases castor is the only option OMHO.

I found Motul 800 to lubricate extremely well, but it left a mess in stock saw mufflers, which I don't necessarily always consider a bad thing.

It is. 3 oz per gallon never fails me. I've been into all of my saws and everything is oily wet. A logger buddy has a 385-395xp part saw boneyard full of broken handles, tanks, and missing fins. But none of them are burned up. Same oil
