The Truth About Fuel Additives.

Posted in Alt Fuels, auto industry, Television, Videos by MrAngry | August 3rd, 2010 | 3 Responses |

Ever go to the store and see a can of octane booster on the shelf. I know I have and I’ve even been known to purchase a can from time to time. In the back of my mind though I always wondered if it actually did anything, either good or bad. Some people say that if your running low-octane fuel in a higher compression engine that this stuff will in fact raise your octane level, while others say they’ve felt massive gains in performance. For the most part though I think we want to feel justified in our minds because we just spent $8 on a can of the stuff. I recently found this video done by the UK’s Fifth Gear TV show where they put four of the major brands of octane/power boosters to the test and I must say that the results surprised even me.

    I wasn’t suprised, but my dad has been telling me those don’t work for years, and he’s been a mechanic for 30.

    There’s probably a very narrow range of circumstances where these will help, but none of them involve production motors and unleaded gasoline. Also, you’re not going to get a 10% horsepower boost out of a bottle, unless it’s a nitrous bottle.

    There are only two additives I would ever put in my gas tank, and neither claims to add horsepower. I always throw Stabil (fuel stabilizer) in the gas can for the lawn mower, and I used to use it off season in the bike. To keep my fuel injectors clean, I’ll run a bottle of Techron through the gas every 10,000 miles or so. Techron is the ONLY fuel system cleaner that’s readily available and actually effective. The rest aren’t worth the plastic they use to mold the bottle.

    The Lucas brand in the US should have been included. It’s the only one that says it gives real octane points to gas. I used it at the track just to reduce knocking at full power in my LS1 Firebird. It did that, but I also don’t think it really gave me much more power. Then again it’s hard to tell a 10 hp gain in a 375 hp engine just by feel.
