Rated 5 out of 5 by from Take Care of your INVESTMENT! Look, Stihl power equipment deserves to be taken care of. This is especially important during break-in periods when friction & heat will be at their highest. Stihl will increase your product warranty when you purchase HP Ultra Oil in combination with your equipment purchase! Ask your dealer for details. I often wonder if I had been using this oil in my FS-550 a few years back...it wouldn't have seized up! Trust me, I do use it now in my MS-362, MS-661, BR-600, FS-460, & FS-560. That is way too much of an investment in equipment not to take care of. Friction performance is way better than standard 2-cycle mix.

Rated 5 out of 5 by from Expensive but Impressive So Far I stated using Stihl Ultra Synthetic 2 stroke oil last year. I use it not only in my Stihl equipment but also in equipment from other manufacturers. Previously, I was using the Stihl Premium 2 cycle oil and 91 octane gas. I stated having quite a few carb issues with this mix in the last 2 years so my dealer suggested given the Ultra version a try. Since I started using it, I have noticed: easier starts, better fuel efficiency, increased power and performance, and it appears to be cleaning out carbon deposits as it works as well. All in all, the oil is expensive but from my experiences, it seems to be worth it.

Rated 5 out of 5 by from HP Ultra Oil - The Best!!! I run this in all my 2-cycle and 4-Mix STIHL machines and I do not seem to have any of the carb or starting issues I have seen in reading many of the reviews on this site. I use the pre measured bottles for 1 gal of the HP Ultra synthetic oil and 1 gallon of fresh 100LL Aviation Fuel. The machines seem to love this combination and appear to give a bit more power and run a little more eager on it. I've actually given a few bottles away to friends with mixed brands of machines for them to try it "risk free" and they all seem to love it too. I think this product is a winner!!

Rated 5 out of 5 by from Best engine protection This oil additive prevents gas going bad within 30 days...Shaking the gas can before each refueling​ also helps. Engines run cooler with synethic oils...Making them last longer..this the best value of all.

Rated 4 out of 5 by from Great for 4 mix engines I purchased this oil to extend the warranty of my FC 110 Edger. This edger idles and runs better when I use this mix. I have tried it on other two strokes and it works well. However, I notice a slight odor when I use it on non-Stihl 2 strokes. I have not noticed any smoke but I run it at exactly 50:1.
