I had a email conversation with a klotz rep about oil in my saws. (Background info. My dad raced unlimited offshore years ago, and one of my (departed) uncles raced semi pro mx. Both were big fans of klotz) he basically said I wasn't going to see any real gains with the super techniplate over r50 or their snowmobile oils. Which lead me to think if I can get good results with a "cheaper" oil then why not. Maxima was always a favorite in the rc community, and now that you mention it, I use motul foam air filter oil. I should have thought about them ad well.
My dad and my uncles(his brothers)raced snowmobiles in the early and mid 70s. They ran Kohler 440 free airs in Arctic Cat sleds. They worked closely with Kohler engineers and they started running Klotz synthetic oil when it came out. Their piston failure rate went way down after the switch. It's good oil.
 
Cool morning, my grandson graduated from Kindergarten in 9:30 service, my son is on first day of a short break between jobs. So, I decided to retrieve another of the big sections of oak from down over the sidehill along my driveway. This 9' log is about 30" diameter, and according to Sherrill's green log weight table, over 2500 lbs. Too big for either my tractor or ATV, so I hitched the 4Runner to bull pull this up the hill to my driveway. I had to reverse direction and finish this pull because of the utility pole.
A quick minute make the last part of the pull.



It was too big for my log arch too, so I bucked it there on the driveway. I'll have to at least quarter the rounds to lift into a cart to take to my stacks for finishing the splitting.

Anyone care to watch 4 minutes of Dolmar 6100 with a 20" bar working through this log:

 
Because almost all of my saws are ported so they need more protection than a stock saw, it is cheap insurance, and your saw will last longer.

Ported saws run higher RPMs and have more stress, ditto for big bores/hybrids. Milling is also very tough on saws, so I protect mine.

I have NEVER blown one up.

I built a 440 big bore (Asian) for a friend of mine. I ran the saw quite a bit w/o any problems. He blew it up.

I built him another, same thing.

I built a 3rd one for him and told him he had to run Saber at 40:1 instead of Stihl synthetic at 50:1 and the saw has lasted much longer w/o any problems.

So, in answer to your question, because it works!

50:1 is to "meet emissions" and does not provide much additional protection. The skirt on the intake side of your piston will wear faster.

I also stopped using "used motor oil" as bar oil because I was ruining bars using it. Buying real bar oil is also cheap insurance.
Roger. Maybe I should start running 40:1 in my ported saw's as well as my stock saws. 👍 I run all my saw's pretty hard to begin with anyway! Haven't blown one up yet, but like you said. ☝️More insurance.
 
Klotz super techniplate. May switch to r50, or some other brand oil..see what's cheaper atm. That gallon cost $48.99 two years ago. Just can't wait to see what it's up to now.
That stuff really gummed up my ported saws…no bueno…
 
Just out of curiosity? Why don't you guys mix 50:1?
Ok so here's the quick and ugly of things. I'm into 1/5 scale rc. I also love chainsaws and just about anything with a 2 stroke. In rc land our 32-35cc engines typically dyno between 7 and 9hp. Very high rpm (21k) and high load demands on them. So most guys go crazy with 30-25 to 1 oil ratios. Most of these engines in stock form would be considered ported compared to our saws. I typically run 40 to 1 in mine. Now our saws for all purposes are low performance, but high load. The 50 to 1 is a pure emissions thing. There is factory documentation that most saws over 60cc (from husqvarna) should be in the 33 to 1 range. My 2 go to saws for years have been a 562xp (60cc) and my 390xp (88cc) so to avoid confusion I run them all on 40 to 1. I have yet to have issues with engine longevity, or seized any engines. Now if we want to look at my old mc cinder blocks even the pm605 suggests a 16 to 1 oil ratio on a straight 30wt engine oil. This was true for the 10-10 as well. They suggested a lighter ratio with a specified mcculloch 2 stroke oil mix. They both live (lived in the case of the 10-10, I don't own it anymore) happy lives on 40 to 1 oil mix.

Really the ratio can be determined on 2 factors alone, expected load and top rpm. 2 strokes are a wasted lubrication system. It cones in with the fuel and is burned during combustion and or expelled with the exhaust. So the faster we spin an engine the less time it has to stay (oil) in the engine to do its job. Oil saws spin pretty slow in the greater scheme of things. Then we have expected load. Our saws spend most of their time pulling a chain through wood, doing a hard job in sub optimal conditions. So they have a high load. So there for we need more oil to keep things lubricated properly. This mainly is for piston wear as the bearings can live a pretty happy life with minimal oil. (So long as they don't get excessively hot)
Once you factor in modern synthetic oils, and additive packages you fund you don't really need as much oil as you think. Really some where between 33 and 40 to 1 is sufficient for most of our saws. (Larger displacement, milling etc). Now when we look at the broad range of power equipment and their tasks, factor in epa requirements you quickly come to realize that homenowner use far out weighs that market and the higher oil ratios for moderately powered engines isn't needed. Thus you have the std 50 to 1 ratio. It's fine, just ideal in many cases. Larger displacement and higher loads just need a but of extra cushion.
Really when you get down to it it can't really hurt the equipment at any rate, so long as the carb is (can be) tuned for the higher amount of oil running through the engine.
 
That stuff really gummed up my ported saws…no bueno…
The castor content can gum them up if they sit around a lot. Was one of the talking points when the klotz rep said about using the r50. I haven't had any issues over the years with it. This gallon is marked to mix 50 gallons of gas at 50 to 1 so I'd assume I'm closer to 45 gallons or so at 40 to 1.
 
This is the stuff I run for mix. It's pretty spendy so if your looking to save money on two cycle oil. This isn't for you. However, it's great premium oil, but comes at a premium price! A also run additives. A lot to be said about good fuel detergent's!

This is the bar oil I run. I get a discount buying it by the case. 👍 It's good sticky stuff!IMG_20220603_191418032_HDR.jpg

The MOTOREX I run is close to 40$ a "quart" where I live! Consider yourself lucky! 😂😉
 
Since there have been no wheelbarrow pics posted.
Yeah, about that... unfortunately I won't be doing any for a while. Got me a new knee yesterday. Hopefully the physical therapist sees the wheelbarrow with the same therapeutic value that I do, otherwise I will have to try something new. It will be a shame to lose her.

Looks like it will have to be nothing OR recycled pics, photoshop pics, or pics of loads I get the H-girls to do in my absence.

For the "this thread is worthless without pics" crowd. NOT a chainsaw incident.

Wherever will I find a PT that would agree that firewood chores are good therapy???

@Cowboy254 are you busy this month?

Wow buddy, you gotta warn a guy, wasn't expecting leg pictures this early :laughing:.
Hope it works out well for you. As much as you complained about it, it was obvious you needed it ;).
If you need a hand with anything down there let me know and I'll see if @Brufab can come give you a hand :laugh:.
Seriously though, let me know, you know I get around lol.
 
Thanks. You been getting around less at $5/gallon I think. ;) Been waiting on you to pick up your pine noodles on your next trip eastward.
Not really, just taking the car, hard to get as much in it though lol.
Yesterday I bought two new pair of boots, an MS311 that was overheated(obviously the wrong oil or mix ratio :innocent:), and then I got a call for a 60 gallon air compressor I had emailed on a bit before I left.
We made it work though :laugh:.
@backywill probably take the pine noodles, or is it the needles he likes :).
Had to remove the motor and compressor and put them in the trunk.
