Lucas Oil 10020 Upper Cylinder Lube/Fuel Treatment - 5.25 fl oz.

I’ve been using Lucas Fuel Treatment for a while now, and it has become part of my regular maintenance routine. It helps keep the fuel system clean, the engine runs smoother, and I’ve noticed improved throttle response. The large 1-quart bottle is a great value since it lasts through multiple fill-ups. Easy to use—just add the recommended amount to your fuel tank. Definitely a product I’ll continue buying.

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.

This will save your cars engine, I’ve used it religiously in my cars and no issues even on a 8841 mile trip and a 5500 mile trip across the desert and in harsh conditions

A win, win product good for saving your car & wallet.

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 pergallon (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.

Excellent fuel treatment that actually makes a noticeable difference. I followed the recommended mix ratio, and the improvement in engine performance was noticeable within the very first tank of fuel. The engine felt smoother, throttle response improved, and it seemed to run cleaner overall.Great product for helping maintain the fuel system and improve performance. Definitely something I’ll continue using regularly.

Definitely got better milage. After 2 tankfulls I went from 325 to 345 with 3 gallons left.I've used this product for decades in diesel engines and seen a few mpg improvement, so a 20 mile per tank improvement makes it worth the cost.

We have a 2017 Acura RDX with 135,000 miles on it, and the past 50k miles, or so, it had an engine surge around 1700-2200 RPM under moderate throttle conditions. I’ve tried a few cans of Seafoam in the past, but no luck. Had it to the shop to do full tuneup and check everything out at 100k miles, then another checkup at 130k. Could not find a problem.Out of the blue, I decided to give this Lucas Oil Fuel Treatment a try. I dumped in 8 ounces into the 16 gallon fuel tank, and topped off with Premium Fuel as always. Took it out to the highway for an hour drive, and accelerated FULL THROTTLE onto the highway from a few on-ramps. Needless to say, the surging problem is GONE!Is it magical Snake Oil? Don’t know, but, “It Works”!!!

buen producto, lo utilizo varias veces al año y se nota en el rendimiento del motor, vendedor de 10, envio rapido

Good

Been using this regularly for 30 years and it’s never let me down. For cars with lots of miles it cuts down on the knocks and noises and for newer cars it keeps it running smoothly while increasing gas mileage and performance.
