Great Performance, but Separates with 100LL Fuel
Maxima Castor 927 is a solid 2-stroke oil that delivers excellent performance in terms of lubrication and engine protection. It provides smooth operation and keeps my engine running well under a variety of conditions. The oil burns clean and leaves minimal residue, which is a definite plus. That being said, I’ve encountered an issue when mixing it with 100LL aviation fuel—it tends to separate. While this doesn’t affect its use with regular pump gas, it’s something to be aware of if you're using aviation fuel in your mix. Overall, it's a great choice for most 2-stroke engines, but be cautious when pairing it with 100LL fuel. Still, the performance and reliability make it a top pick in my book.

Best Oil!!
Love it!! Smells good!! Run in my Honda Trx250r,yz250 and all my blowers and chainsaws. Used to run cheap synthetic in my blowers and eventually have issues. Switched and can tell difference. Using for years. Highly recommend!!

Great 2 stroke oil and also smells good.
The best 2 stroke oil in my opinion. Made from the caster bean. Used for years and never had a engine failure. I use this in my paramotor(ppg) which is a 2 stroke. Also use in all my outdoor 2 stroke tools. Won't use anything else.

Great
I put this stuff in everything air-cooled from ride on lawn mowers to my air cooled 4-stroke motorcycles just a capful in about 2 to 3 gallons and you can tell a difference in performance for sure and heat , it's an old trick I learned from old school desert racers in Nevada as I am a third generation Nevada desert rider they were using it in air-cooled Volkswagen engines and motorcycles as well, All air cooled engines really like this stuff when it's very hot outside I also run it in all my two stroke stuff as well in everything from chainsaws to weed wackers and motorcycles And I've never had any problems when using it. I do not recommend using it in anything with an oxygen sensor or catalytic converter but that's just my opinion.

Works good
Good mix oil. Never had any issues with it in over 3 decades of hard off road riding. Doesn’t smell bad for the people following you either. Seems to work as good as full synthetic.

Best premix oil I've found to use in my old school 1997 Honda cr250r. Burns clean and didn't foul plugs.
