None of these recommended mix ratios on these various oils were made for chainsaws.
Seems to me the common sense thing to do, would be to try some different ratios and see what works best.

It won't be blue will it? Blue goo!!!!!

I see Lucas oil being mentioned and I am curious how it will do. I run Lucas cause I can buy it in bulk locally.
EDIT: Are we talking about the Lucas 2 cycle semi-synthetic oil? Or something else by Lucas?

My feeling with the sabre pro is this: they want you to run it at 70 or 100 to 1 ratio. It may burn very clean at that mix, but I just can't run any of my stuff that thin. Just goes against all we've been taught. I'm guessing that at 40 or 50 to 1 it's much stronger and hence the quick carbon buildup.
My local amsoil guy said he'd fix or buy me a new saw if something broke with the 100:1 mix, but I declined.
I said he could buy a new pro stihl saw and I'd run the snot out of it with his oil at 100:1 and report back, but he wasn't too keen on that suggestion.
I'm not knocking amsoil one bit, just saying it didn't work for me at the normal ratio. It may be awesome stuff at 70 or 100:1 but I'm not gonna be the test monkey with my expensive saw.
My four cycle snowblower and the kids gocart runs very well on the stuff though.

I didn't like the smell it had when mixed with VP and it put a nice black layer on the piston real quickly, and coated the exhaust port with black stuff.
The R50 cleaned it all up pretty quickly on that machine. 800 does the same as far as cleaning from my observations.
You and Hedgerow happen to be the reason I got Lucas, and Brads why I got K2. I have over a gallon of each of them to try out, but they have some stiff competition from 800 and R50.
R50 probably just got moved down a half of a notch due to that low spot I was in this past weekend. It could have been the smell of the tree I was cutting mixed in with the R50 and VP, but the tree smelled like diluted piss and when I cut the stumps, I felt like my nose was overwhelmed with the intensity of the smells. Have to give it one more try on a job with more than 1 tree to be sure. No headache or nausea, just kept spitting to rid myself of that smell

It will do fine, it's all I run now. Is a semi-synthetic...

I can get Maxima Super M for the same price as Lucas which is 50/50 synthetic and mineral. Comparing them all i can see different is the flashpoint on the Super M is slightly higher but Lucas don't really post any specs on their site.

Maybe they changed something, the bottle of off road here has a fruity smell.
Road is pungent lol

800 off-road smells great to me but I mix mine with Sunoco 110.

Most 2-cycle oils labeled for chainsaw use have a viscosity between 7-9 cSts at 100C. The 800's and R50 have twice, or more, viscosity at that temp. We're definitely getting more protection using the thicker oils but I'm not sure how'll they performance versus a lower viscosity oil like Lucas or Motul 710.

If you want to be technical here's the order of oils from the thinnest to the thickest (Viscosity at 100C) according to their Tech sheets in cSt's:
Lucas full synthetic: 7.5
Stihl HP Ultra: 8.45
Motul 710: 8.9
Belray H1R: 12.4
Maxima K2: 13.58
Motul 800 off-road: 15.5
Klotz R50: 18.20 (typical/average)
Motul 800 road racing: 19.2
Klotz KL-200: 22+
Here's several comparison in percents:
Going from H1R to 800 off-road is a 25% increase in viscosity at 100C
Going from H1R to R50 is a 46.7%
Going from H1R to 800 road racing is a 54.8%
Going from Stihl hp ultra to 800 off-road is 83.4%
Going from Lucas to 800 road racing is 156%
I'm considering testing the recommeded "chainsaw viscosities" (7-9 cSt's) to what I'm using now (Motul 800 off-road). I want to determine which will give my saw the best performance. I'll stay with a 32:1 ratio to insure adequate lower and topend lubrication. A 40:1 ratio might be a sufficient amount of oil to protect but I'm using ported saws so I'll stay on the safe side.
Ron, do U know the #s for Saber and the Lucas semi synthetic?
Thanks.
Thanks.

Not sure about Saber but Lucas semi-synthetic is also 7.5 best I remember. Testing, timed cuts, may show the lower viscosities will have the fastest times...just a guess until testing.

I bet that Klotz KL-200 would be great for milling.

11.1 on the Saber Mustang
Super techniplate is 22. Kl 300 which is the closest thing they show on the website is 7.9. They redid the site and lost kl 200 for some reason. I called and they said they had it and would get to work on the website.

I might give Maxima Super M a try for semi synthetic its 12.3 vs. 7.5 for Lucas, i can get it for about the same price.
Its 50/50 with ester synthetic and mineral and i was told Lucas was 70/30 with only 30% being synthetic but not ester.

That KL-200 looks "thicker than molasses in the winter time". That oil must be a "50 weight" but protection should be super.
Thanks Keith, that looks like a good # to me.
Higher may not always be better. It is like you don't want to run straight 50 wt oil unless your engine bearings have been clearanced!
