Lucas Oil10013 Fuel Treatment - 1 Gallon

I’ve been using Lucas Oil 10003 Fuel Treatment in my vehicles for several months now, and I’m really impressed. After adding it to my fuel tank, I noticed smoother engine idling, better acceleration, and even a slight boost in fuel efficiency. It works great to clean and lubricate the entire fuel system, including injectors and carburetors.What I like most is that it’s compatible with both gasoline and diesel engines, and it helps neutralize issues caused by low sulfur fuel. It feels like a tune-up in a bottle, and it’s definitely helped keep my engine running smoothly. Plus, it’s a cost-effective way to maintain engine performance and longevity.I’d recommend it to anyone looking to keep their engine in top shape!

So I've been using this in 2 cars for the last 6 weeks. A 2019 Honda Civic 1.5L and a 2016 BMW 528i 2L. Both cars very well maintained. Starting with the Honda the first tank of gas I put in 6 oz. Overall the car was running pretty good before the treatment but would shake at stop lights at times to a point of putting the car in neutral just so I wouldn't feel it. Didn't notice much of an improvement after the first tank. Second tank cut back to 4oz. Started to feel some results. No more shakes and hold the rpm to a steady 600. Third tank and the car is running the best it has in3 years. The BMW I just bought 3 months ago 84k miles in very good condition but was a bit rough and noisy running. First tank 8oz in and I could feel some things happening. Slightly better running. Second tank, 6oz in. Like the Honda the improvements began. I started to get a odd burning smell at times. No leaks so no worries. 3rd tank and still running better with the smell sometimes. I'm pretty sure carbon is burning off and that's what the smell is. I'm seeing what looks like soot on my chrome tips at times. No doubt the car starts faster and runs smoother now. I'm very interested to see how it runs after another couple tanks. Overall this stuff is a great value but don't expect instant results and I wouldn't recommend using it as a one and done. Buy a gallon and add it to the gas for at least 6 tanks of gas. Your motor didn't go bad in 400 miles and bringing it back will take some time too.

Been using this fuel additive for the last 12 years can really see and hear the difference when not used I do get a mileage increase with the increased fuel mileage, I believe this product pays for itself. But also, the engine runs smoother, I use it in both gas and diesel engines and in diesel engines, it makes it so much quieter I also added to fuel that I leave in fuel cans the only downfall to this product is if you use more than what is recommended as I used to do It would foul out spark plugs sooner than needed. But that was my fault, not the product I would highly recommend this product works great in older engines with high miles also very effective in both carburated and fuel injected engines

I’ve been using this in my vehicles for over 20 years. My 2004 Chevrolet Avalanche Z71, with a 5.3L engine runs as smooth as a sewing machine.This vehicle uses zero oil in between oil changes. It idles so smooth at traffic lights that you can barely tell that the engine is running.During Covid this vehicle sat parked for nearly two years. When we started driving it again it ran perfectly; even with two year old fuel in it. A true testament of the fuel conditioning aspect.

I use this in all my diesel engines. It keeps system clean and helps lubricate top end. I have been told that my top end is one of the cleanest my mechanic has seem. I use this every fill up. Works for me and I trust lucas brand.

I recently tried out the Lucas Oil 10003 Fuel Treatment in my car, and let me tell you, it's a game-changer! 🚗💥 My engine runs smoother, I've noticed an increase in fuel efficiency, and the overall performance has improved significantly. It's like giving your car a nice, refreshing energy drink!I can't recommend this product enough. It's like a magic potion for your vehicle that works wonders. I've been using it regularly now, and I've seen a noticeable difference every time. If you want to give your car some extra love and care, this fuel treatment is definitely the way to go. Trust me, you won't be disappointed! 👌✨

After adding this fuel treatment to my tank, I noticed a significant difference in how smoothly my car ran. The engine felt more responsive, and I could feel the increased power during acceleration. Not to mention, my fuel consumption decreased noticeably, saving me money in the long run. 🌟💰

Hi - I don't write reviews on car products. However, I've been using this Lucas injector cleaner on 3 2011 BMW X5s with 150,000 miles, and 2006 Saab with 145,000 miles for over 5 years, every fill-up using the recommended volume. All 3 X5s and the Saab run smoothly.When I changed the Valve cover gasket on my Saab, the cylinder heads looked spotless. I thought it might be because I don't usually drive the Saab since the X5s are the daily drivers.When the X5s went through a preventative maintenance, we installed new glow plugs. The engine in all X5s were in great condition and clean. Since the X5s are diesel, we've used Lucas DPF Cleaner + this Lucas Injector cleaner together for each fill-up using their recommended volumes, for more than 5 years. I've seen few regen events and the DPF has little to no back pressure. All vehicles pass California Smog tests with flying colors.I frankly didn't expect that. Given my experience, I feel compelled to share. I get 600 miles per tank with the all 3 diesel X5s. My 2006 convertible Saab still runs strong.There you go! Hope this helps someone, too.Safe drive!
