Use in Audi 2018 Q5. Really helps. FYI, use with PI every now and again. Note: I live in Boulder Co. at this altitude this product seem to really help performance.
I use this octane booster in my 02 wrx and it works wonders. I always buy a case and keep them on hand. This is a life saver if you have pumps that have only 89-90 octane ratings.
Bottom Line
Yes, I would recommend this to a friend.

I use Dominater Octane Boost every 2-3 tanks of regular 87 octane gas. My 65 SS Impala runs noticeably better with it.
I have used Amsoil products for over 20 years and have always been happy with the results. My recent purchase of Octane Boost has proved to be no exception. I used it in my 2003 Harley Lowrider this weekend and honestly, the result was something that made me not want to bring the bike home. Smooth application of power especially at low RPM and just taking off. Engine ran noticeably cooler and it may sound crazy but the exhaust note was slightly different. There was more........growl to it than before. That I noticed but did not expect. On the highway and climbing hills the increased performance was quite evident. Now, it was not an engine overhaul, and nothing magic, but for a noticeable improvement in overall performance give Dominator Octane Boost a try. I am certain you will like the feel.
