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

[KG441c]

So using my crappy solvent filled FD rated claiming Maxima Super M @ 42:1 in everything from MS 192T-390xp what ratio of oil am i really using?

Fifty

 

[Deleted member 83629]

wouldn't the solvent makeup of some of these oils be from the the fuel stabilizers used in the oil.

here's a list of all the oils we are considering.

http://www.maximausa.com/msds/2stroke/Super M.pdf here's super m. guess I didn't have it on my list. you look at it and make an estimate.

Super m minimum 30% solvents

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?



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.

So you pretty much didn't have a clue till you googled it..
The ash content of 800 is the highest I have ever seen for a 2 cycle oil..It wouldn't pass fd/fc by this alone.
And you only think that about solvents because you don't have a clue what your talking about..

this has ran 2 yrs worth of husky xp oil at 32:1
you guys see a problem? rings are not stuck and appear to be fine.

I have never been a fan of Husky oil. This pic reinforces that opinion.

Why don't you enlighten us then?

For you guys looking at plugs...you cannot correctly read a plug unless you're looking at the very base of the porcelain. Typically you have to cut away the metal to really see it. With that said, a properly tuned 2-stroke will generally have a cocoa brown colored plug. Additionally, this will vary based on the oil and fuel used. For these reasons, I consider it a very poor method to use to tune a saw.

Super m minimum 30% solvents

How do you figure. It says 5-15%..

i just got a basic tune on mine 4 strokes out of the cut then cleans up in the wood.
i rarely look at plugs unless it is hard starting.

I agree but we used it on dirtbikes quite often with good luck

On?

I didnt I was guessing. What he really is trying to say is that Yamalube is terrible by the solvent content?

 

[Deleted member 83629]

all this talk of oil plugs i might try the woodland pro in the 5 gallon pail the saw mill is using up the road.

Not sure what im looking at[emoji10]

I think its all supertech from walmart and relabeled!!! Lol!!!

solvent naphtha medium aliphatic is basically stoddard solvent/ kerosene
polybutene is a smoke inhibitor

And he's nuts...

 

[bwalker]

ash is a measurement of residues left after burning.
ash is what makes up the solids in smoke and can contribute to hard deposits.

So it's just like wood man heh






75% oil. so at 32:1 of 710 it's actually 40:1 ...why he said run at 32:1.

Again your completley wrong..
Ash refers to the amount of mettalic ash when reacting an oil sample with sulfuric acid... It has nothing to do with smoke.
JASO puts a limit on ash and there is no way 800t would meet jaso-FD because it's ash content is through the roof.

PIB is not a smoke inhibitor per se. It's a high molecular weigh anti scuff base stock. It lowers smoke when blended in a oil because it burns cleanly without smoke.
