Rated 5 out of 5 by from EXPERIRECED THE RESULTS At the City of Newport News we use no other oil except Stihl's Ultra oil. We mix upwards of 2700 gallons of fuel for our fleet yearly. Maintenance costs went down and production went up and its environmentally friendly too.

Rated 5 out of 5 by from Good as it gets I have run this in my backpack blowers for years with zero problems. I do like the fact that is doesn't smoke as bad as other oil mixtures. Just bought me a FS 56RC weed-eater and you can bet this oil will be used in it.

Rated 5 out of 5 by from No Carbon I Have Been Using HP Ultra in my BG 55 since Purchasing it in New 2011 it is now 2018 and had a Little Bogging with the Throttle. Thinking it might be the Spark Arrestor I Remover it and Much to my surprise it was a Clean as the Day it was put in at the Factory no Carbon deposits at all to resolve the Throttle problem I adjusted the Low end screw a Bit and it runs like a Champ

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.
