Sporadic , premature piston slap issues also in air cooled MX applications within the same observed overall oil deficient applications !
So what's the current Two stroke oil favorite for

No surprise that the Caster based oils with their anti galling properties performed well . No Saber , Dominator or Interceptor tested ??
Yeah Ultra performs well in the intended 4-mix , trimmers or blowers , however has limitations within tuning in conventional saws . It can be tuned to perform however not a clean burning oil at those ratios in homeowner or even ported saw applications .
Which stens oil? because the pillow pack is packaged by opti but the other stens oil i don't know anything about.
Wasn't real fond of how Schaeffer's performed but those oils you listed perform fine.
Is ultra a ash less oil? i know it leaves a nasty deposits inside a engine and has a horrendous odor.
low smoke / odour & detergent / dispersent additives is the difference within (FB & FC) & the Superior Jaso FD ratings . The FD rated products allow much heavier oil to fuel ratios , since it will abate the potential. excessive carbon or smoking & odor issues . Actually if you ever noticed Sabre has a quite high viscosity , which is most likely why it allows leaner oil ratio's due also to high level of detergent / dispersent additive package .
according to walmart website super tech full syn is rated API TC.
Not if your engine is properly tuned.
Schaeffer may well be in the same oil class as Amsoil Dominator within your application bud . If you don't run it as recommended you will have " dirty oil issues " . If used as recommended by Amsoil it performs very well indeed ! I think I will check out the Schaeffers product line further for specific gravity / density & flash point characteristics .
I got a bottle of interceptor but the lack of color bothers me.
i ran it in my lawn boy it is a TCW3 oil
Has anyone compared Stihl Ultra to Amsoil Saber in a Stihl MS500i? The fuel injection system should keep the optimum air/fuel ratio regardless of oil mix ratio, but Stihl has made it clear to me that their warranty does not extend to oil rations greater than 50:1.
Yeah a FB / FC compliant Jaso type oil . However think it is a semi synthetic TCW marine grade oil , not a good saw oil choice !
I never worry about colour , I mix with a measuring cup & my containers are application specific labelled . When mixed at 50 : 1 it provides a distinct colour difference then straight gas , so I am know lol.
I don’t really know for certain, other than it was designed for them.
Yeah well that will give you minimum quality protection with maximum fouling issue potential , like what Ultra users sometimes experience . Schaeffers also produces quality semi & full synthetics , which have been proven to be a premium world class snowmobile race oil . I have to check out my. Race oil guide that goes back to my Klotz Benol & R-50 caster oil race days lol.
The castor based oils tested more in the middle of the pack due to the ring lands clogging up causing lack of compression.
Dominator, Red Armor, and Honda HP2 we’re in the top 5. Saber was about #10. Interceptor wasn’t tested
I am sure they do but i don't recommend there oils for a lawn boy even though lawn boy engines spec a ashless oil of tcw3 quality.
Yeah run it in my 4-mix for 5 yrs . at 50:1 . Still required decarboning at valve lash adjustment intervals . I switched to Amsoil Sabre same ratio awesome results . I might try some Dominator & Interceptor , since its a power broom application , which is in winter hibernation lol
Figures , we always decarbonize every teardown between racing weekends on the aircooled bikes & more on the liquid cooled snowmobiles due to their inherent cooler internal temps . Usually ran a one temp higher spark plug range , however never had a engine oil related failure .Dirty oil but bullet proof for anti galling racing protection . Thanks bud !
