Review: Worth the Upgrade - I’ve been running the Lucas Oil octane additive for years and thought I’d treat myself to this after what seemed like declining returns from the Lucas in my pickup. After two fill-ups with Royal Purple additive I’m kicking myself for not investing in the right product long ago. At ~4000 ft above sea level, my manual transmission supercharged Tacoma feels like a different vehicle: better throttle response, less engine noise, and better economy AND no more residue on my tailpipe to boot. Driving in town isn’t such a chore anymore and turning it loose is that much more enjoyable - if you’re looking at this and are using Lucas’ additive try it and I bet you’ll be impressed too. Review: Better maintenance record when using the Max Boost Octane - I use this in the gas tank of my 2017 Toyota Land Cruiser with every fill. The car runs better & I have had no major mechanical issues. The gas mileage, while not good, is better when I use the Royal Purple 11757 Max Boost Octane Boost. ## Features - For best performance, follow the manufacturer's recommendations in your vehicle owner’s manual. - Reduces engine knocking and pinging - Raises octane rating up to 30 points or 3 numbers - Restores power and fuel economy ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B072K4S96B | | Best Sellers Rank | #30,907 in Automotive ( See Top 100 in Automotive ) #356 in Motor Oils | | Brand | Royal Purple | | Customer Reviews | 4.8 4.8 out of 5 stars (243) | | Date First Available | June 9, 2017 | | Item Weight | 5.05 pounds | | Item model number | 11757 | | Manufacturer | Royal Purple | | Manufacturer Part Number | 11757 | | Product Dimensions | 9.2 x 7.1 x 6.5 inches | ## Images ![Royal Purple 11757 Max Boost Octane Boost Case, 16 fl. oz (6 Pack) - Image 1](https://m.media-amazon.com/images/I/61IwKzbO1rL.jpg) ## Questions & Answers **Q: is this a case of 6, 16 oz. bottles?** A: yes, 6 - 16 oz bottles **Q: I have 90 in my area will I need a full bottle to make 93 or half with 18gallon tank?** A: one bottle treat will 18 gallons or if you want to be precise one ounce per gallon of unleaded fuel. 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth the Upgrade *by J***Y on August 28, 2024* I’ve been running the Lucas Oil octane additive for years and thought I’d treat myself to this after what seemed like declining returns from the Lucas in my pickup.

The car runs better & I have had no major mechanical issues. The gas mileage, while not good, is better when I use the Royal Purple 11757 Max Boost Octane Boost. ### ⭐⭐⭐⭐⭐ Good product *by E***E on June 1, 2025* I haven't used it yet but I'm sure it will be fine. Royal Purple is a well respected brand. I need it for my scooter (moped) as I have REC 90 gas available but the scooter store recommends 93 octane which has ethanol and I don't want gas with ethanol. This will solve my problem. I'll put some in my car from time to time to keep the engine clean and performing well. 1 can would last for several years with the scooter, they get 100 MPG and I only ride it locally. ## 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.
