Lucas Oil 10003 Fuel Treatment - 1 Quart

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!

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! 👌✨

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 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.

Followed directions for use and product works as advertised. I use it regularly on a high mileage car and miles per gallon has improved enough for me. Just buy a 7oz bottle and refill from the can to use when filling tank.

I had a stumble/stall when starting off, very bad on 2016 cruze with 60k miles. Added Lucas to tank and drove ~100 highway miles. When I hit the destination town the stumble was gone and my car runs great. Seems an excellent product.

Ordered and got next day. Saved a trip to the store and saved a little money. Use at every fill up of ⛽ to keep injectors clean. Buy this product all the time, first time buying online. Will buy again. Lucas products are awesome 👍

Top Tier quality fuel cleaner and will keep your fuel system from clogging up and your injectors from spraying weirdly making your engine perform better as a result. This big bottle is great for using it every 6 months or so or every time your change your oil. Far better as a preventative method than having to replace your fuel pump fuel lines or fuel tank!
