I've been using Klotz benol for over a year. I do not recommend using it in a chainsaw. Ya I know....yippie another oil thread. Lol. 3...2....1.....and go!
years ago we had a guy riding snowmobiles with us that ran Klotz beaniol. We told him if he was going to run it that he was going to ride in the back. That crap stinks!!
Have and always will use Husky, Stihl or Echo 2stroke oil. Though there are many choices out there, IMO "the big 3" oil is specifically formulated for small 2stroke power equipment. Is there magical elf potion in it? Likely not. Has it always performed well for me? Yep. I see no reason to explore the other options.
Try original Shaun. It will mix with any fuel you can find and I never had one do that kind of mess. Motul 800 leaves a similar mess if you don't get it hot enough to burn. Any of the castor will like 927 and super techniplate.
I plan on trying the original or Lucas semi synthetic. I try to buy local when I can and my bike shop only carries benol in klotz brand is why I've been using it. A oil debate is not my intensions of this thread. Just showing what benol looks like after a lot of use. Not just a few tanks. I have two saws that are a flipping mess.
No doubt. A lot make a mess cutting firewood. Milling you can run anything since it will be hot enough long enough to burn. Maxima k2 works good too if they have it. A little pricey compared to the others.
I just use the high end Stihl oil, and my saw runs great and the exhaust is clean and the saw runs sweet.
So I have a story about using klotz in a brand new chainsaw. I bought my first house about 3 years ago and the yard needed cleaning up. So I went to my buddy(husqvarna dealer), he pointed me to one. This was before I was into chainsaws so I couldn't even tell you what it was lol. Something smaller than a 445. Anyway I had a dirt bike at the time and was using super techniplate in it and thought it would work fine for a chainsaw. After about a month one day after using it hard it wouldn't start. Back to the dealer with no compression. He disassembled it to find the ring ask gummed up and stuck in the piston. Now idk if it was the oil or a dull chain that caused this. Remember this was before I find sites like this and learned to sharpen a chain. I mean I tried to sharpen it but nowhere near as good as now. Anyway my buddy got that saw covered under warranty. Instead of fixing it I got a new 445. I've ran husqvarna XP oil ever sense and haven't had any problems.
Unless you were running the saw like a mad man, the dull chain in my mind would not impact the rings. The two stroke ratio simplistically is the ideal point for combustion and corresponding lubrication. Too little oil, ouch, and with too much you get poor combustion, fouled plugs etc. I would think for the standard pump gas, low to high grade, the standard mix is ideal. Maybe guys running hot saws on high octane can add something to this?
What would you consider "standard" mix? At that time I was instructed to run 50:1 and did. I've sense gone to between 36 and 40 but usually closer to 36. No problems with stuck rings even though I run more oil now.
I use the Stihl premium oil, and I buy the small jugs that require 2 gallons of gas per jug. Check this out. STIHL HP Ultra 2-Cycle Engine Oil
