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

Rated 3 out of 5 by Synthethic HP oil only average. I no longer use the Stihl HP Ultra 2 cycle oil. Doesn't match up to the higher quality 2-cycle oils I've used. Stihl HP Ultra is only JASO-FB certified. The best ones are JASO-FD or ISO-L-EGD. The price of the Stihl oil is as much as the highest quality certified oils on the market. When you pay premium prices you should get a premium product. A JASO-FB oil is not a premium oil. They make excellent pro saws but their oil is only average. They need to produce a higher quality oil to match their pro saws. January 17, 2014
Rated 5 out of 5 by HP Ultra oil High Power Ultra oil. Absolutely amazing oil when mixed with 89/91 grade gasoline. I only use this oil in my Stihl equipment and REALLY makes a difference. The engines run SO smooth and clean and the gasoline seems to last longer too! I can not recommend this oil enough. Try it and you will the difference in the first run! December 8, 2013
Rated 5 out of 5 by great oil The Stihl HP Ultra synthetic oil has become one of my favorite oils for my two-cycle engines. It burns clean and seems to actually clean old engines when I run it in them. October 30, 2013
Rated 5 out of 5 by The best there is. I've been using motor oils for years now on my RC plane gas engine and none got to the results this oil did.The engine is cleaner than ever, no carbon on the pistons, the spark plug is very clean but, wet, so the engine is NOT running lean, the exhaust ports are very clean like the day Ive got the engine, and I can tell you this after running more than 35 Gal with it .Before that I ran a different kind of oil, a premium style, that left a lot of carbon in the engine, the STIHL cleaned it all.
