40+ year old , oil technology !

Both very high quality oils . Have used both in numerous saws . Never had a problem within any properly tuned & operated saw .

Yeah , Ultra controversy is definately ongoing . I thought I should provide an update the Stihl White bottle was relabelled as "Premium" up North here , manufactured by Castrol .

Solid information Kevin ;)

I run 20" bars on my 50 cc & 57 cc Husky 345 & 357 . My 5105H has a 20 " & 7900 I run 24 " & 28 " depending on what I am felling or bucking . I routinely run a 36" on my P-51 on larger pine / for cutting applications .

That may well be true , it is an extremely effective solvent !

Nice ride by the way !

Actually Seafoams active ingredients are 60 % kerosene 25 % Naptha & 15 % isopropyl alcohol . Cheveron & MMO have similar products that substitutes the Kerosene with Stoddard solvent . Stoddard solvent can have either benzene or xylene or toluene component mixtures which are quite hazardous to...

Thanks for the clarification Kevin , way to many folk do not realize the effects that poor quality fuel has on the mix quality of 2T engine performance & longitivity . I have seen more sponge & choking of 2T engines , due to improper tuning to the mix , which can be compounded by inferior fuel...

FC rated Dino air cooled oils @ that ratio tuned on the edge of lean tend to not pool a lot . Quality mineral oils with a lower viscosity index, burn & seal rings well & clean ! P.S. Group III mineral oils are rudimentary syn. quality grade oil without all the additives !

A 60 / 40 mix of lubricity & solvency in a can ! If your mix is fat to the tune no problems !

Any current modern 2T oil will suffice as an effective assembly lube . Even Ultra is better than dry fitting engine components , unless your welcoming cold seize potential lol.

If you have your saw tuned properly to oil ratio & run it hard , a Jaso FB rated oil will perform adequately . FB oils tend to not completely burn in the fuel charge & leave residual deposits behind .

Yeah , you can run it that rich , no reason to , its has a high viscosity index but is an ester based oil with additives . If your saw is tuned for it , you would not see any negative results. Interceptor & Dominator are also fine oils , even without Jaso certification imo .

In competition hot saws , race saws ok , any other application its counterproductive !
