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

[KenJax Tree]

Its very easy to tell, its a dark red like Klotz

 

[KenJax Tree]

Ok this **** is getting old ONCE-AND-FOR-ALL which one would you use at 32:1-40:1 for commercial use?

 

[bwalker]

Any particular reason why?

I don't like to run injector oils in a pre mix application .

 

[bwalker]

Bwalker you raced boats right? This is on a quart of Dominator i was given...why is this?View attachment 422258

Maybe because like I have said all along..Esters make poor storage lubricants.

Either of the Maxima oils.

What about ester blends?

On the performance side of ratios and viscosity this is the way I think. You can only force x number of oil molecules through a fixed orfice at any given time? H1r / 800t/ r50 makes a saw go leaner at a given tune where the saw was tuned to handle a less viscous fluid(k2,r2, 710). Makes sense why Redbulls saw ran close to Matts saw?

That would depend what they are blended with.

I would lump those other oils in with H1R.. for Instance K2 idles and cuts at the same rpm as yamaha 2r at 32:1, which had the idles and cut at the same rpm as Husky silver bottle at 50:1.

I've read on MX forums about guys having rust in the bottom end using Dominator....because it has no rust inhibitors? Google Amsoil Dominator rust and a few different things pop up. Thats why i asked about it here.

IMHO most of the whole rust thing comes down to improper maintenance and lack of use. Run the saw, bike or whatever every few months and rust will never be a problem. Besides saws aren't ran through standing water like MX bikes anyway.

Its not so much my saws those get run everyday all year. Mainly my weedeater, blower, and hedge trimmer during the winter, i use E free gas so i just fill them all the way up, however I do start them periodically during storage.

I have had ester oils corrode brass black in days not weeks..it happens.

I tested 3 oils at 32:1. Videos are uploading and on this wifi I expect 2 hours for all 3. Motul 800 and Klotz super idled at the same rpm around 2800-2850. K2 was higher and more erratic. It bounced from 2900-3100. Motul 800 was tuned to 13.8k before 3 cts and after was 13.9k. Klotz was 13.9k before and 14.3k after. K2 was 14k before and 14.4 after. The K2 was at 14.5k before and I tuned it back down. I haven't timed any videos since they're loading from my phone.

Did the saw seem a little down on power with the K2? It kind of sounded that way to me.

I kind of thought it felt like it. Need to time those videos here with the stop watch. It got leaner in the 3 cuts and I tached them right after I turned the camera off. It was the only one that really creeped up a lot.

The klotz super smells the best by far. I used it in the 7900 ripping with the mini mill until in the 2nd cut the bar came loose and got the chain a little. I finished by noodling the others with a 34" bar on the 390. Burnt about half a gallon of Super in pump gas doing this.

 

[mdavlee]

Times I got

800
6.31
5.95
5.68

Klotz
5.67
5.51
5.47

K2
5.83
5.54
5.64

Interesting. Must have just been putting more load when running K2.

 

[KenJax Tree]

So the K2 sounded the slowest but was faster than 800

Load.
