Designed to treat up to 10 gallons of fuel, it also cleans gum and varnish build-up, ensuring optimal engine performance and longevity. ## Description Octanium Unleaded is a VP octane booster that gives your octane a boost of up to 7 numbers (70 points). Compare that to the boost provided by other brands. In fact, many brands don't even specify their actual octane boost number while others only provide a boost of up to 3 to 5 numbers. Octanium Unleaded is safe for limited use in cars and trucks that have oxygen sensors and catalytic converters. Furthermore, VP's unleaded octane booster is a true engine performance enhancer that improves throttle response and acceleration when used as directed. One 32-ounce bottle treats up to 10 gallons of gas (38 liters). Review: Great Octane Booster - All I can say is this stuff really works. I have Nissan Skyline R33 and I put 93 octane gas in my car. With this stuff I can raise my octane up to 7 points which gets me at 100 octane or very close. As soon as I step on the accelerator I can feel the difference getting an instant increased in horse power because of the higher octane. I love this stuff it really works. Review: Great for engines that adjust timing automatically - Butt dyno feels like it provides my 5.0 Mustang with 40 or so more HP. Definitely more eager to accelerate faster as RPMs climb faster, I use 1.5 cans per fill to reach 108 octane when added to the 93 octane in my full tank. ## Features - One bottle treats up to 10 gallons of fuel (38 Liters) - Gives high octane boost of up to 7 numbers (70 points) - Improves throttle response and acceleration - Eliminates gum and varnish build-up - Size - Quart/32 Ounce ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07P13524K | | Best Sellers Rank | #58,510 in Automotive ( See Top 100 in Automotive ) #16 in Octane Boosters | | Brand Name | VP Racing | | Contains Liquid Contents? | No | | Customer Reviews | 4.6 4.6 out of 5 stars (263) | | Global Trade Identification Number | 00846781006141 | | Included Components | VPRF29505 | | Item Form | Liquid | | Item Type Name | AUTO_ACCESSORY | | Item Weight | 1.9 Pounds | | Manufacturer | VP Racing Fuels | | Material Features | Unscented | | Number of Items | 1 | | Scent | Unscented | | Specific Uses For Product | Octane Booster | | UPC | 846781006141 | | Unit Count | 32.0 Fluid Ounces | | Warranty Description | Manufacturer Warranty | ## Product Details - **Brand:** VP Racing - **Item Form:** Liquid - **Material Feature:** Unscented - **Scent:** Unscented - **Specific Uses For Product:** Octane Booster ## Images ![VP Racing Fuels 29505, Madditive Octanium Unleaded Octane Booster - Quart (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/51figkd8g0L.jpg) ## Available Options This product comes in different **Item Package Quantity** options. ## Questions & Answers **Q: This is safe to put my 2017 Subaru sti?** A: Absolutely. Increasing the octane will only prevent engine damage that preignition causes. Octane is a measurement of the fuels ability to resist detonation. It is tested and given a AKI # Anti knock index. Using a higher octane then necessary will only burn up your cash faster. But using a lower octane when the engine needs higher can/will harm the engine. **Q: Will this work in my 2015 focus st?** A: It woke up my corvette. The stuff really works **Q: It left sediment in my clear gas can after one week. Has anyone else had this issue. Can I just shake it up and use it?** A: People usually put it in the tank and add proper amount of Fuel so can't really say, maybe next time I'll put it in a Clear glass jar and get back with you **Q: Is it safe for an every day car? i’m just looking for something that will clean my fuel system and improves gas mileage. taurus sel 2011** A: If you follow the instructions you'll be fine. 2.6 ounces per 10 gallons, I believe, if you have emissions control devices on board, which you probably do since you don't have a race car. These guys dump the whole 32oz in their tanks and keep rollin'. I can understand your confusion. The video and bottle say two different things. If you are nervous, just go with Liqui Moly Fuel System Cleaner or Amsoil Performance Improver (Amsoil PI) every 4,000 miles or at your oil change interval. And use Amsoil Upper Cylinder Lubricant and CleanBoostMAXX on every fill-up. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Octane Booster *by M***Z on May 4, 2025* All I can say is this stuff really works. I have Nissan Skyline R33 and I put 93 octane gas in my car. With this stuff I can raise my octane up to 7 points which gets me at 100 octane or very close. As soon as I step on the accelerator I can feel the difference getting an instant increased in horse power because of the higher octane. I love this stuff it really works. ### ⭐⭐⭐⭐⭐ Great for engines that adjust timing automatically *by E***D on January 8, 2026* Butt dyno feels like it provides my 5.0 Mustang with 40 or so more HP. Definitely more eager to accelerate faster as RPMs climb faster, I use 1.5 cans per fill to reach 108 octane when added to the 93 octane in my full tank. ### ⭐⭐⭐⭐⭐ Great product for your engine *by G***S on March 18, 2022* With all the 💩gasoline available to the public my car was what we used to call spark knock, not a engine miss but poor performance and ponging under slight acceleration. I took a chance on the VP Adative I poored it in before refueling w/ the usual 93octane which is what my 06 G-35 Sport Coupe MT-6 the minute I drove 2-3 miles the spark knock / engine ping completely went away and the car performance feels great and seems to have resolved my issue. So yes great product and if you're suffering from the same issues I was experiencing then I would very highly recommend this specialty product.
