I've been using Lucas Oil Fuel Treatment for the last few years, specifically after every oil change on my cars. Initially, I used the 5.25-ounce version, but I realized that purchasing the 1-quart version is more cost-effective. Performance: The results have been impressive. My average miles per gallon (MPG) typically hovers around 30-31. However, after using the Lucas Oil Fuel Treatment, I consistently see my average MPG jump to 36. This improvement is based on my daily drives, which involve 50-70 mph speeds over 3-6 hours. Cost Efficiency: Switching from the 5.25-ounce bottle to the 1-quart version has been a smart move financially. Not only does it save money, but it also reduces waste, as I'm not tossing out small bottles every time. Effectiveness: Lucas Oil Fuel Treatment has proven to be highly effective in enhancing fuel efficiency. The noticeable increase in MPG has made it a staple in my car maintenance routine. Given the amount of driving I do, this product not only saves on fuel costs but also seems to improve the overall performance of my vehicle. Pros: Significant increase in MPG (from 31 to 36 on average). Cost-effective when purchasing the 1-quart version. Easy to use, just add it after an oil change. Potentially improves overall engine performance. Cons: None observed so far; the product delivers on its promises. Lucas Oil Fuel Treatment is a reliable and cost-effective solution for anyone looking to improve their vehicle's fuel efficiency. The substantial increase in MPG is a testament to its effectiveness. Whether you drive long distances daily like I do or simply want to get more out of each gallon, this product is worth considering. ... show more

    • Another no brainer from Lucas
Size: 1 Gallon Style: 1 Pack
Let me start off by saying I can't speak to the MPG increase that others claim - I'm not saying that it isn't there, but all of my machines are gas guzzlers at heart to the point I simply don't pay attention. That said, I add Lucas Fuel Treatment to everything I own from my C8 Corvette, my boat with the 496 MAG HO, truck, jet skis, mowers, pressure washer, 4 wheelers, side by side, etc. Along with some other 5 star products that I'll mention below. My primary reason for use is it's an upper cylinder lubricant. I do also run SeaFoam Marine in all of my equipment as well mainly for cleaning and fuel stabilization - I prefer Marine over the original SeaFoam because it does not contain alcohol. I'm not saying that Lucas doesn't do the above because it does, but Lucas is much thicker making it a better lubricant (in my opinion) where SeaFoam Marine is somewhat thinner and to me the cleaning properties are a lot better as that's what it was designed to do years ago. You can mix and match these as you please, and you can't overdose your engine. Here's my strategy: Lucas Fuel Treatment: great upper cylinder lubricant for heavy use situations (high RPM use like 4 wheeler engines, tracking your car, heavy towing etc) Add pretty much every time I fill up, and I add a heavy dose to my truck before I do any towing. Also keep topped up on Lucas heavy duty oil stabilizer. SeaFoam Marine: one of the best injector/carburetor cleaners you can use and an equally good fuel stabilizer. I've added this to 2 stroke fuel mix for my weed eater almost 4 years ago on the same fuel and still runs flawlessly. I add to my road vehicles every so often for cleaning and before any long term storage, however I add to my smaller engines almost every fill up (ATVs, UTVs, mower, jet skis, etc) If you don't want to spend the extra money on SF Marine, the original is still fantastic. But if you are running non-ethanol fuel in your small engines, it makes sense to use the Marine so you don't add any alcohol to your fuel. Had a hesitating fuel injected 4 wheeler that had been sitting for months, stalling at idle. Added a HEAVY dose of SF Marine through it (to the point I could smell it burning out of the exhaust), did a few 3/4 throttle runs up and down the road and it cleared it out quickly. Ran as normal it for the rest of the trip and completely eliminated the stalling/hesitation. STAR BRITE Star Tron: when heavy cleaning is needed. Have injectors or carbs that are heavily clogged and gummed up? This stuff should loosen it up. Minimal lubricant properties, only use when needed. All in all, you can't go wrong with anything from Lucas or the above brands. I've tried to turn people on to these before and have been met with "it's snake oil, not needed" however I haven't had a SINGLE fuel issue in anything I own since following this strategy. Today's fuel sucks and a little preventative maintenance goes a long way. ... show more

    • Quieted rough idle
Size: 1 Quart Style: Cleaner
I've run a full tank with about 6 ounces and am now on my second full tank with another 6 ounces. So far I have actually noticed it quieted down my engine. There was a considerable ticking from what I had believed was the injectors. After the first full tank it's noticeably quieter with a smoother idle when stopped in gear. I track my mileage pretty closeley and get around 380-400 miles per tank. The last fill up I was at 450 after using and am currently half way through my second and averaging to get about 440 out of this one. For the price point it's worth it. I'll run the whole quart through and see how I feel about continuing but for now I'd say I'm happy with the product and from what I can tell it's doing some good 👍🏻. ... show more

    • Great for your vehicle
Size: 1 Quart Style: Cleaner
Great to add to your fuel to give it a little extra treatment for your vehicle, I use the measure amount about every 3rd fill up for my truck. It runs better when doing so in my opinion, been using for years. Recommend for high mileage vehicles. Great product!
