    • ost-effective way to maintain engine performance and longevity
Size: 1 Quart Number of Items: 1
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! ... show more

    • A must for engines!!!!
Size: 1 Gallon Number of Items: 4
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 ... show more

    • worked great
Size: 5.25 Ounce Number of Items: 1
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.

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.

Size: 1 Quart Number of Items: 1
I give this 5 Stars. Having just loaded into my Mercedes and Chevy Trailblazer. Because all the reviews I've read. This is a very highly tested and rated product. As with any other Lucus product. I have no doubt this will live up to the high standard of all Lucus products. Not to mention the Great Price For A Product Of This Quality.. Vehicles are under 35 Thousand Miles.. So I didn't need a Super Harsh Fuel Treatment. ... show more
