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.

Rated 5 out of 5 by from Great oil! This oil is not only good for stihl, but other equipment. It runs great in my BR200 and I expect it to run great on my stihl tools I plan to get. If you need oil for 50:1 tools, use this. Don't worry, youl love it!

Rated 5 out of 5 by from This oil is great for all day and everyday use. This Ultra oil is great for rugged commercial use. I use it in all trimmers Fs70r, Fs 240r, and other 2 cycle equipments like blower and chainsaw. It also great for 4 mix/ 4 stroke hybrid too. This oil is best to use for rugged commercial use and if you care for reliable, and longivity or if you have 4 mix then that oil is for you.
