If your looking for one of the best products in this category of fuel injector/system cleaners, then this is a product you should consider. I belong to a club of Mazda RX-8 owners, tuners, and technicians and many of us use this product with very good results - especially since it will stand up to the high operating temperatures a rotary engine runs at (especially under load) as well as its added lubricating properties.
