    • Great for Cleaning and Lubricating the Fuel System
Size: 1 Quart Number of Items: 1
Used this fuel treatment in my daily driver and noticed better throttle response after a full tank. It helps clean injectors and adds some upper cylinder lubrication. Easy to use and worth the small investment to keep things running right. Highly recommended for routine maintenance.

    • Better than I expected. Good stuff!
Size: 1 Quart Number of Items: 1
I'm impressed! I didn't expect this to work, but I actually noticed a few things: - Car starts up much faster (less "cranking" required to start the engine) - Feels a bit smoother and more power Not sure if its placebo but it definitely seems like it works! Considering this is so cheap, I will definitely buy it again. ... show more

    • Highly recommend
Size: 1 Gallon Number of Items: 1
This stuff is incredible. My range went from around 390 to 413 and it keeps climbing. That’s about 5% increase of range. My long term average MPG went up 0.2 mpg after only 2 tanks. Those numbers don’t lie. My car also feels way more responsive. I’ll keep adding this stuff to every fill up.

I've been using this product for many years and have had numerous vehicles go well over 200,000 miles with no fuel issues. Keeps the injectors and carb clean.

    • Best product on the market
Size: 1 Quart Number of Items: 1
Have been using Lucas products for a very long time, no complaints, only quality products that actually work. Bought a newer vechile this last January, 2015 Pathfinder, and it was not getting quite the gas mileage I was expecting, starting using this Lucas upper injector cleaner before I did a extensive and expensive coil and plug change, as I have with every vechile I've owned the last 20 years, and after only a few fill ups, had improved gas mileage by nearly 2 miles per gallon. Tried about every other brand on the market, nothing comes close! ... show more

    • Best Fuel Treatment on the Market.
Size: 1 Gallon Number of Items: 1
Lucas hit it out of the park with this product. It keeps the fuel system, including injectors, fuel lines, and upper cylinder of your engine clean. This is my third gallon of this product I bought. I keep a single use bottle filled with this in my truck, and I try to use it with every fill-up. I've missed a few, but for the most part every time I fill up, I put in a small bottle of this and just refill it when I get home. I have a friend who had a lifter/cam failure on his 5.7L Hemi. While scoping the engine to look for metal shavings, the mechanic commented on how clean his top end was, and definitely didn't look like an engine that had 100K+ miles on it. Admittedly, he didn't change his oil as often as I do and learned a hard lesson. I was sold on this product then, and have been using it ever since, and will continue. It's just good insurance. These new trucks aren't cheap, and this product, along with a quality synthetic oil & filter changed regularly help keep our expensive trucks running smooth for a LONG time. ... show more
