Rated 5 out of 5 by Primum Oil , Great product. I started running this oil last summer in all my 2 cycle engines . And they started preforming like new . Recently purchased a MS 250 and the dealer and he insisted I buy a six pack to extend warranty . And per 2.8 oz bottle by buying it in the pack it is actually cheaper than what is sold in the box stores . For avabilty the local general store here even sells it. November 22, 2015
Rated 5 out of 5 by Great oil I own several stihl products, BG 56, BG 86, KM 90R, KM 130R, BR 600 Magnum, and HS 45, I use to run the orange bottle in all my equipment but was told by the dealer I needed to switch to the silver bottle because I kept having to replace my priming bubble due to it cracking and the silver bottle will not eat the rubber fuel lines. After switching to the silver bottles I have never had to replace another priming bubble, great stuff November 13, 2015

Rated 5 out of 5 by Best 2 cycle engine oil on the market use this in all my 2 cycle equipment and it preforms better then any other type of oil. I use it in my still products that run at peak performance and with my non still power equipment and they run even better. March 2, 2015
Rated 5 out of 5 by Ecxellent for RC gasoline engines. Cleanest oil I've found. I am a Radio Control Airplane Hobbyist who flies gasoline powered planes, using engines very similar to those found in a chain saw. This oil has proven to be the best we have tried at our club so far. Some of my fellow club members and myself were using very expensive high end oils from different manufactures but found that the Stihl Ultra outperformed them all. It is not that the other high end oils are bad; they are just not design for such small engines like the Stihl Ultra is. The biggest difference we found was in how clean the engines look from the inside when using Stihl Ultra. The difference between two engines, one using Ultra and another one using anything else, is evident right away. July 10, 2014
Rated 5 out of 5 by Cleans Engines This stuff cleans engines especially after you have broken them in with mineral oil. I really love the way this oil makes the engine performs. I was using Lucas Semi-Synthetic and switching over didn't make much of a difference but I would rather have a full synthetic rather than a semi-synthetic. My only concern is the smell that it produces when burnt. The High Performance orange bottled 2 cycle oil smells way better. After this was used up I used Royal Purple Synthetic and it smelled a little better. The engine performance was the same from switching, but it leaves residue on the exhaust port on the cylinder. Will be switching back to the HP Ultra. May 19, 2014
