Itasca seems to be MA approved, good stuff and cheap.
Now here we have some interesting pictures about amsoil vs that sweet sweet precious Lucas oil............apparently according to amsoil the lucas stuff is garbage
Here is a link to the study they conducted: https://www.amsoil.com/lit/g3466.pdf
Here is a summary of the study:
The test used four ECHO string trimmers, with SABER Professional used in two and LUCAS SemiSynthetic 2-Cycle Oil used in the other two. Computer-controlled actuators simultaneously operated the trimmer throttle triggers according to an identical protocol for each unit.
Test administrators monitored engine rpm, spark-plug temperature, exhaust emissions and other parameters to ensure consistent, repeatable operation and gauge overall performance of each trimmer. After 300 hours of operation, the trimmers were disassembled and inspected.
And here are some of the highlights. .
So you see, we KNOW for a fact that it is easy to spend big bucks on oil, but does that mean your expensive oil is saving the engine?? "potentially" "maybe"
But we have reports of guys running cheap marine stuff for decades... so maybe it's best to do that and save some money for parts... It's like if you run the cheap stuff you WILL have enough money saved to rebuild the engine with new parts....while the big buck spending means...maybe those parts will hold up to justify the cost??
The walmart marine stuff does work fine for a long time....But to be fair the price you pay for getting the walmart stuff means doing business with walmart...it's terrible in there. . I think my next bottle of oil will actually be some Pennzoil semi marine oil... Lots of good reports from reputable members here and I can get it delivered from Amazon with no visit to horrible Walmart with the screaming children and crowded store and people cutting you off and weird smells....Yuck!!
I have some Lucas actually in my garage...now I am scared to run it due to the Amsoil tests......jk.. you can't win this game... run what you can.. and don't look down on the cheap shit because even the expensive stuff has it's flaws...there is no universally accepted "Best oil"....but there is cheap and "good enough"
