Reviews

HP Ultra 2-Cycle Engine Oil is rated 4.8 out of 5 by 31.
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.

Rated 5 out of 5 by from question about mixing my own fuel Since I don't use my chainsaw or blower that often I like to buy small quantities of oil. It comes in 2.6 oz which is 77 ml. I have a 2.5 l container for the mix. But at 50:1, 77 ml does not work out. What size oil should I get to measure the fuel easily?

Rated 5 out of 5 by from More power in all my Fuel Mix Engines I tried out the HP Ultra oil to get the extended warranty on my pole pruner, Hedge Trimmer and Blower. They run great with this oil, no super bad odor, no blue smoke, just smooth running engines, BUT what I didn't expect was when I fed it to a 13 year old Husqvarna String Trimmer that had run on Husk'ie oil its whole life. just the beginning of the tank through the machine and it magically picked up what I would estimate to be about 200 RPM and ran much better than before. WOW!! I always use fresh gas 91RON and factory oil in my machines, so this was a shock!! I expect that STIHL engines would run well on it, but I was shocked about the performance gains in the 13 year old trimmer!!!! I will never run anything else in any of my engines. HP Ultra is well worth the marginal increase in cost.

Rated 5 out of 5 by from Best Option for Your Tools Originally purchased this oil to extend the warranty on a new chainsaw and became hooked to the quality operation of all my stihl engines. This stuff is superb and will make all your 2-cycle engines reach peak performance. My three stihl tools chainsaw (MS 271), trimmer (FS 130), and blower (BR 600), all burn this oil and I have found it to be superb. I switch to the pre-mixed product for my last run each fall/winter. Use this oil - you will not be disappointed.
