I use this in my Shelby SC Cobra 427. If you are just trying to bump up the rating I would find 93 fuel as it can get expensive to use at each fill up. I run only 93 NON ethanol gas and use it at each tank refill but then my car is primarily a show car. Hope this helps. **Q: Is there a mixing chart for this stuff? Does more product mean higher octane numbers?** A: I don't know of a mixing chart and the octane level would have to increase more product. If I were you I'd contact Royal Purple. I'm sure they could answer your questions. **Q: Can I mix this with 93 octane pump gas?** A: My 92 Volvo requires 93 octane. I got water in high test so decided to use regular gas and add booster. Very happy with the result as plenty of power. ## Frequently Bought Together - Royal Purple 11757 Max Boost Octane Boost Case, 16 fl. oz (6 Pack) - Royal Purple 18000 Max Atomizer Fuel Injector Cleaner - 6 oz.
