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.

Smel ver nice 👍 plenty protection for my Athena 70 scoot at 50:1, I'm probably killing brain cells by sniffing my exhaust. Worth it 💪

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
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.

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.

Ohhh that smell! Can't you smell that smell?!
Mmmm the castor 927 is the best premix I've ever used. Been using it for almost 20 years now and swear by it.The stuff smells amazing and I've never had any issues fouling plugs or gumming up power valves. I've done countless top ends after using this premix for over 100+ hours at times and the wear has been very minimal.This has been in every 2 stroke motor I've ever owned. From my kx 80 almost 20 years ago to my recent YZ and RM 250's. Not to mention my weed whackers and small generators. It's a bit pricey compared to the cheaper premix, but this ester based 927 is the real deal.Buy it, mix it and enjoy the smell!
