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

[KenJax Tree]

But like what has been said, maybe AT/MT run too rich for oil that thick. Maybe Brad the tuning whiz can make it run cleaner on a regular carb saw.

Only makes sense if u wanna run the thicker oils, 800t,h1r, r50, and they have a performance disadvantage at 32:1, why not just run it at a higher ratio?

If that's the case here, I'll certainly move on. I wanted to try it though. Jog my memory. What are you running now?

Brad you should try 800 off road!

looking back at emails with belray - http://www.arboristsite.com/community/threads/oil-test-32-1-vs-40-1-vs-50-1-results-info-condensed.277566/#post-5305420


viscosity #'s may not be the whole story...

-----------------------
Redbull says -

why does h1r have a great film strength if the viscosity 100c is only 12.4 ?

------------------------------------
Belray -

The type of ester that is used has a very high polarity so it has a strong bond to metal surfaces, and because of its high stability, it remains intact in high pressure contact points.

---------------------

Do you have any Motul 710 to try? This oil has esters.

 

[KG441c]

Where did the 12.4 value come from? I didnt see it in MSDS

I've run it before. I don't remember the details, but no complaints.

 

[KG441c]

Ok I woulda thought higher also.

I used it at 40:1 i'm not going higher than that. K2 or Lucas for me but might try Super M instead of Lucas next time.

I haven't had a problem with the 550 and the 800 making a mess. The rest of my saws aren't autotune so I don't know if that makes up the difference or not. The 550 to me runs a little leaner than I would like.

l ran 1/2 a tank of Motul 800 through my saw. No issues, great oil.lol

The oils in question are designed o run at ratios even lower than 32:1. It is the application that's miss matched.. why not just ran something that works better?

 

[KG441c]

It would work wouldnt it? What would be the difference running a thinner oil at 32to1 and running a thicker oil at 50to1?

RR or OR?

I picked up 4 bottles of
MAXIMA k2 today and the same number of Motul 710 to try out.
FYI I haven't been able to respond to this thread for several days. I get an error every time I try to log into the site.

I just ran 3 tanks through the 661 with H1R @ 32:1 this weekend
I also ran 3 tanks through the freak (ported/snotted 066 by mdavlee) of R50 @ 32:1

Fuel was VP from a new 5 gallon jug for both.

The 661 piston top is brown dusty buildup
The 066 piston top is just about clean as new

I will run the next few tanks in the 661 with R50 @ 32:1 and keep an eye on the piston top

I will NOT be purchasing any H1R anymore, no matter what anyone else says and regardless of what anyones results show

Out of all the oils discussed on this thread H1R is the one I would run dead last.

Bearings last longer with more oil, ring seal is better and HP is higher as documented by Mercury marine.

I'm wondering if MTronic runs richer than normal though.

The 066 was 4 stroking through 1/2 the cut after I leaned her out
The 661 was 4 stroking only at the start of each cut

To me, the 066 was sooooo much fatter throughout the entire weekend

So r we still saying the high viscosity oils at 32to1 wont combust as they should and hurt performance?

Do u believe that 800t at 32to1 offers no more protection against wear in the bottomend than yamalube @ 32:1?
