I have been using Opti-2 for over 20 years for commercial use and have never been let down. It will extend the life of your equipment. I only use the best products. Most of my 300+ units make it 20 years.
Just wanted to let you know what I think of your product, nothing better! I have a chainsaw bought in the mid 70's and have run Opti-2 in it from about '77 or '78. I had to put a carb kit in it today and was amazed, there was no carbon on of the piston at all. The piston look as though there had only been one or two tanks burned. The biggest problem is other parts are getting hard to find. All my other 2-cycle engines have performed extremely well with Opti-2. I cut about 20+ cords of wood a year and while this is not my only saw it has been used a lot over the years. Thanks, Barry.
I started using Opti-2 many years ago and I have never been let down. I have used it in my 25 to 1 outboards as well as 60 to 1 chain saws. Around 8 years ago I started using Opti-2 in all my 4 stroke small engines. The stabilizer and small amount of oil seems to agree with all of them. My personal record involves a Wisconsin-Robin powered plate compactor left on a job site, uncovered, for 18 months. It started on the first pull. My John Deere lawn mower always starts on the first or second pull in the spring and runs great all summer. The ease of mixing with your pre-measured packets takes all the guessing out of it. I currently work as a groundsman for a school district in Eastern Washington and have converted all of our grounds equipment to Opti-2. We have around 100 2-stroke units and our carb problems have nearly disappeared. We also use the product as a storage fuel for seasonal equipment. Thank you so much for a wonderful product.

Walker's Saw Shop Ltd would like to take this opportunity to recommend the use of Opti products in all your outdoor power equipment. We have recommended the Opti products to our customers for over 10 years and will continue to do so in the future. We sell over 300 chainsaws and over 200 handheld units per year to the professional and the consumer and every one of the units are PDI and are ran in with Opti-2 cycle mix at the recommended ratio.
Thanks, John Walker.
Thanks I have used this oil for about 17 years. I have a few friends that now use it. Best oil for 2 cycle. I had a back pack blower that my son filled with regular gas and ran the blower for about 1/2 tank of gas was gone. I added Opti-2 to the tank it never had a problem. Now that blower is about 18 years old and still running never changed anything but a plug.
Todd with MO Dept of Transportation: I use the 55 gallon drums of Opti-2. Buy a drum each year (past 5 years). I have no plugs fouling or exhaust screens plugging up. My crews like going to work and not having down time. Opti-2 just works. If you could, I am looking for names and numbers of distributors in my area.
At my request not too, while I was gone, my wife mowed part of my pasture. She did not check debris on cooling fan. As near as I can figure the engine was run for at least an hour or more with no cooling at 80 degree day. Engine finally quit on her, I started it after cool down. Found out it got so hot it melted all plastic parts contacting the oil, like dip-stick and bottom of filler tube, but the engine still ran pretty good. Am replacing the engine. I am AMAZED the engine STILL runs. You may be interested in teardown to see type of damage with such high operating temps. I figure maybe in the 400 to 500 degree range. Engine has ran since new with Opti-4 oil for 157 hours.
I would like to thank you for producing the best two-stroke oil I have ever used. I just sold my Titan aircraft that had a 503 52hp Rotax engine with a total of just over 600 hours running time and 10 years of trouble free flying. For the sale condition inspection of the engine it checked with a compression of 120# and 122#, that's like new. I would also get 80 to 100 hours without having to change the spark plugs due to oil fouling.

I just bought a boat with a 130hp Yamaha outboard that has an oil injection system on it, as of this time I am also adding Opti-2 in the fuel as a safety in case the oil system would fail.
Love this product...I just made the switch this winter in my ice auger for ice fishing on the recommendation of a guy doing some carb work for me. Will be using it in my summer yard stuff too. Can you send me a decal for display in my rod building shop? I have a few customers asking what I use in my auger...nothing other than Opti from now on!
Good Day...I'm a long time Opti-2 user in all of my two cycle products...a perfect product. I read somewhere that you can actually use the two cycle mix in a four cycle engine without causing any damage. Is this true? Also, just a note here to praise the stuff. I recently crashed a large model aircraft which completely demolished it including the 3.2 cu in gas motor which literally had 250 hours running at full throttle. When we recovered the pieces and were able to take what was left of the motor apart, we were very pleased to see that Opti-2 has kept the insides sparkling clean for many years! Thanks.
