I’ve been using this Lucas Fuel Treatment in my vehicle and the results are great. My engine runs much smoother, and I’ve actually noticed a slight increase in my MPG as advertised. It’s a very easy way to keep the fuel injectors clean and neutralize poor quality gas. This 1-gallon size is a fantastic value since it treats up to 400 gallons. Highly recommended for any car owner!

This fuel treatment works well and is easy to use. After adding it to the tank, the engine ran smoother and seemed more responsive. It helps with performance and gives peace of mind about keeping the fuel system clean. No issues or side effects, and it does exactly what it claims. Overall, a solid product and a good value.

This a great product that I have been using for years in my 2011 Ram 3500 Cummins diesel. I have no affiliation with this company and this has been a test of time. My truck now has 201,000 miles on it and I have had zero issues with my engine and or any part of my fuel system, this mixture will treat your fuel system, for moisture, raise your cetene levels for more horse power (noticeable), add fuel milage, keep your injectors and injector pumps clean and lubricated, keep your compression brake clean and working properly. NOTE!!! I mix this 50/50 with Marvels Mystery oil about 16oz per 34Gal of diesel on every fill up, well worth the price.

I have been using Lucan Oil/Fuel Treatment in my 2004 F250 for about four years now. It seems to run better (I really don't drive it all that much, unless I need lumber or feed) or for hunting. The truck seems to give me several more miles per gallon (when one is only getting 10-12 mpg) it's a nice thing. For the price, it's a simple treatment, putting it in the gas tank doesn't take more than a couple of minutes, and the results are well worth it. I had started using it in my 2017 Subaru, when for some reason, it had developed a slight miss, and Lucan appeared to have cleared that up. Some folks swear by this product, some don't. You be the judge. I like it for my truck.

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.

I recently tried out the Lucas Oil 10003 Fuel Treatment in my car, and I'm happy with the results. I noticed a smoother engine performance and improved fuel efficiency. I use it during long drives, and it has been quite handy. Plus, it's wallet-friendly. Oh, and the freezing temperature in my apartment didn't bother me while pouring it into my tank. Overall, a good buy for maintaining my vehicle's health.

Hold on to your hat! This stuff is incredible. First use: About 4 ounces in a full tank. No effect. Second Use: About 6 ounces; no noticeable difference. Third use: About 8 ounces in a full tank of gas. About half way through the third tank, the car turned into a veritable tiger. It absolutely screams off the line, without the earlier engine jump rise at the start. Smooth and fast. Very quick off stop lights and while passing. Much quieter, too. Like new. I have a 2007 Hyundai Azera 3.3L V6. This has been great engine, with only the valve cover gaskets and alternator replaced, beyond regular oil/tires/brakes. And the valve cover problems are a known issue with this engine and year. In fact, Hyundai replaced the gaskets on the Santa Fe using this 3.3L engine. (But not the Azera.)
