Lucas Oil 10013 Upper Cylinder Lubricant Fuel Treatment - (1) Gallon 4-PACK

Fast shipping, a bit better cost wise than buying off the shelf and a LOT better price than a truck stop!

I use this at every fill up. I actually need to purchase more.

This product has saved me $ every time I go to the pump. My car requires high test due to having a turbo charged engine. Even when running high test I kept having to take it in to GM due to issues with the turbo kicking out. Two years ago a friend told me about Lucas and I started using every tank full and now only use regular fuel. Not only does it save me $ but I have had zero issues since started using. I had it in the shop at least 12 times prior too.

I drive a 2023 Ram 1500 Laramie with a six inch lift with size 38" tires 13 1/2 wide. This truck is bad ass and drinks gas, put Lucas fuel into your tank and you take control with more power and yaa I get an extra 2.5 miles per gallon and keeping my engine lean and mean. That's huge, truck lovers will agree! I put it in all my vehicles now!!!

Great for keeping the upper engine clean. No noticeable improvement in gas mileage, but my engine does run nicer. Safe to use every tank or to just go with an oil change as part of your maintenance program.

I will buy this again soon so long as pricing remains competitive

I like the product

I have used the stuff for years and I’ve never had an injector or a fuel problem on any of my diesel tractors or trucks
