Great 2-stroke oil for my outdoor equipment
I use this oil in all my chainsaws and outdoor equipment such as weed trimmers and blowers. For a little added protection, I mix a 40:1 ratio. I always use non-ethanol fuel treated with Lucas Fuel Stabilizer and Lucas Octane Booster. I was so impressed with the performance of all my outdoor equipment using the formula described. If I had one complaint, it would be that there is NO color to this oil which could be catastrophic if someone thinks that the fuel was properly mixed, but wasn’t. I always make sure the oil and other additives go in the empty tank before adding the gasoline. I then put a piece of masking tape on top of tank beneath the handle with the date and info about additives written down with a black Sharpie. Be sure to shake gas tank before adding to equipment as well as shaking the equipment itself before cranking. I have read reviews that say the treated fuel needs to be shaken before use. This fuel mixture will make your outdoor equipment run so well and smell so good! I love it!

The best!
Excellent product! I'll be honest I bought it to run in my weed whacker because I miss the smell the Castor makes! That exhaust smell instantly brought me back to hanging out with my buddies riding dirt bikes and not a worry in the world! Man I miss those days!
