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

[Ron660]

I burned 1 gallon of oils last year milling. R50 showed no wear or build up. KL 200 was the same. K2 works great but the fumes are a bit rough. H1R I can't stand and on a couple saws I couldn't get it rich enough for my liking. 800 works good with no build up and will leave a wet piston even if up run out mid cut from a full tank.

One of the best experiences/answer I've read on this post.

That's quite the testimonial. Unless there are significant performance gains to be found with a less viscous oil like Motul 710 or Maxima Super M, I see no reason for you to consider anything else. The only other reason I could think of would be the cost factor for someone doing that much cutting all the time.

Klotz is cheap. $1 more than lucas so I can't see changing for a $4 /year in mix.

I ran out on a 390 and 395 mid cut and neither scored when running out of fuel. One was with R50 and the other with 800. I'm sure a run from idle at a full tank to empty was plenty heat soaked. I don't even cut the saw off to refuel. It was boiling the bar oil one day when it was 90-94° outside.

I would love to see your results with 710 & Super M. Obviously what your using works well, but your use would make a good test bed.

800 exceeds jaso-FD how could it be high ash? lol

ron660's piston looks like **** btw so maybe your right!

Do you even know what ash is?

 

[bwalker]

Injector oils they help the viscosity be correct for injection, and they are cheap fillers to increase profits.

They help keep the components blended too.
No one adds them for fillers as solvents are expensive..

You gotta remember the guy answering questions is a Bel Ray tech so anything not in Bel Ray oil is trash.

Just ran a tank of r50 mixed with 1 gal. 110sunoco/87efree@ 50/50 for 98.5 octane @ 32:1 through my 241c. Last several cuts were wide open and shut saw off right after last cut. Saw never ran better! Didnt notice much smell from the r50.

At least you know what I mean now !!

As far as the smell, wait until you are stumping or in a gulley or ditch on a calm day

 

[KenJax Tree]

Everyone has a different smeller, R50 gets to me fast but i like the smell of K2 and Super M (they smell same, that's why i think Super M has K2 in it) but others think K2 stinks.

per Jaso...

The JASO FD spec is 0.18% ash, less than 1/5 of 1% of ash content in the oil. Sulfated ash is the way to measure ash content by the way and its biggest contributing factor is metallic additive such as zinc and calcium.

Hows that?

The help keep the components blended too.
No one adds them for fillers ss solvents are expensive..

Well considering gasoline is the biggest solvent in the gas oil mix. I'd have to say that any 2t oil that needs a bunch of solvents to keep components blended...well just plain SUCKS

According to belray - yeah I know they are "biased". But the solvents are the cheapest raw material in 2t oil. Maybe maybe not, but it doesn't seem like a statement that is that far fetched at all.

Thats a good answer ,but i still do not know what ash is ,

I would say the 241c mtronics burns the 98.5 race fuel and the 32:1 r50 just right?

I thought ash was whats left over after I burn wood in my fireplace.

plug looks ok run a few more tanks and pull the plug again.

What is the plug suppose to look like?

 

[Deleted member 83629]

well im use to plugs looking leather brown but i dont have any strato or mtronic saws
