I should have snapped a few photos of the yamalube r2 in the exhaust port this morning after running. Just as much oil as 800 or r50 and just as clean with very little smell while running. Very responsive and oil mixed well also
661 Oil Test 32:1 vs 40:1 vs 50:1 ?

What is it you don't like about injector oil or oils that state they are for either?

I have seen K2 leave a better coating of oil than 800 when both we're tuned the same

I can get Honda HP2 cheaper than Yamalube...thoughts?

I ran it in my ported yz250 with great results
In low doses I agree, anything more than an occasional whiff and it will make you literally ill.
I used it in the saws today making the cant. It wasn't too bad with a slight breeze. With no air moving all of them suck to be in the haze when milling.

800 is 82% greater in viscosity than Yamalube 2R. So 32:1 Yamalube is equal to 58:1 800 off-road. Or 800 at 32:1 is equal to 6:1 Yamalube if you're comparing thickness.

Sounds good. With all that said I think it boils down to understanding tuning and what the saw actually needs. These 50 weight oils imo are doing one thing better than the 20 weight oils and thats protecting the bottomend but I agree with bwalker that its probably unnecessary. Redbulls saw ran as good as Matts at a higher ratio because the saw with less oil in the mix processed more useable fuel than it could at 32:1 with the thicker oil? Just adding more oil to the fuel doesnt make the saw run richer but just the opposite ! If u dont accomodate with retuning or jetting to process the extra oil in the mix u will actually get more lubrication to the engine with the thinner oils at the same tune? Myself I believe the thinner 20 weight oils at 32to1 will give adequate protection and all around performance and also the topend will operate as it should without drowning it with too much 50 weight oil and impeding combustion? If u use the 50 weight oil at a higher ratio then u diluted the oil with more solvent and end up with a thinner oil anyway? Why not just use an oil that will mix and combust better and protect equally as good to start with? Thats all just my opinion and may be totally wrong but yall fire away!!! Lol!!

Something else to consider. We discuss too much oil causing more heat and resistance in the topend but does too thick of an oil in the bottomend produce too much resistance and in turn heat? The oil is there to keep the bottomend from excessive heat buildup but can too much oil do the opposite?

Doesn't mixing an oil at 32:1 actually cost more per liter than a ratio of 45:1 because the number of tanks is reduced per container?
For example the loggers making their living buying Ultra at $57 per gallon and risking their bearings at 50:1 (which they never seem to replace) are getting 50 gallons of fuel from the container. That's $1.22 per gallon tax included of oil cost.
I'm not sure I understand how Ultra is so expensive compared to these boutique oils? What am I missing?

My Ford FX2 truck and Ford Expedition both require 5w-20 oil. Wonder what will happen if I run 15w-50 in them?
If I run ultra at 32:1 then $57 a gallon makes 32 gallons of mix at $1.78 a gallon.
Klotz is $12 a quart fit a cost of $1.50 a gallon and no headache after
They typically are pretty thin.
What exactly are you referring to?
Prefer 2R and so did the factory honda team back in the 80's and 90's. They actually pored 2R into honda bottles and used it.
I don't think that's definative. Lots of speculation and that's about it.
I am not following you how you make the jump from viscosity to oil ratio..
Where did you get these numbers from?

Thats part of the concept of more oil in a bottle of 800t than in a bottle of 2r due to solvents. He will be able to tell u how he figured it when he gets up. Hes sharp!!
