So what's the current Two stroke oil favorite for

[CaseyForrest]

I’m seeing lots of mentions for products that aren’t specifically designed for chainsaw applications.

Yeah , probably because we got off the beaten path a little from one oil application to another . Bikes , Outboards , Snowmobiles , Ultralites , Trimmers , Lawnmowers etc . From air cooled to liquid cooled . Its not the oil but the composition of the base oil & other additives to achieve the final product that determines it effectiveness in various ratio's within numerous engine applications & usages. No one oil , can be used exclusively or effectively in one form in all applications . You must find a base point and fine tune from there to achieve optimal performance in regards to fuel to oil ratio's & fuel to air ratio's . That's why a lot of people go the Manufacturer's oil recommendation route . That's a start . Experience enables you to go a better route towards a better oil product for your individual requirements wether it be production felling , arborist takedowns to recreational bucking & limbing to serious commercial milling scenerio's etc .

That’s not cool. It would be interesting to know the ratio of WOT to idle time this saw has seen.

Also, how much fuel has been run through the saw.

Also, how many cold starts and has the saw been allowed to reach normal operating temp and stay there, or has it been a “start and stop” saw since new.

I would love to see Stihl ultra results @ 40 : 1 in a MS-660 Milling saw application !

That looks like a couple of outboard engines that were used for nothing but trolling for hours on end and never ran wide open. Wouldn't expect anything like that in a high rpm chainsaw! CJ

Are synthetic ester oils good?

Are synthetic ester oils good?

Been used in air cooled 2stroke engines for decades and Hot Saws 101 approved

Another one good and cheap (at least in my area) option 8eur/L

I got no clue, I ljust like how my stuff runs on it, my stuff likes this and Wawa non ethanol more than the Stihl motomix,

we do not have it so far ;-) Europe I suspect is one market in this regard

Christ sakes that is awful i can run super tech outboard from walmart in my lawn boys and it looks really nice compared to that.

I got two separate cans of 32:1 at home one with ash less for the mower and the other low ash for the trimmer and keep them marked accordingly

Here is one of my lawn boys a C12 engine from 1957 has a 3 ring piston and uses no roller bearings only bronze bushings. Running 16:1 Pennzoil outboard.

 

[Piotr Pakuła]

why this engine is sideways screwed to the tow truck?

Good cutting ole girl . Yeah the Shell @ 16:1 will protect those Babbitt bearings . Have you inspected the muffler recently for any build up ?
