I put this in my SUV every other fill-up

Kimberly M., Atlanta, GA

I was amazed at the change in my SUV, I have a 2002 GMC Envoy with over 230,000 miles. I love my car because of the options it has. I put this in my SUV every other fill-up and you can tell the difference in the way it idles smoothly plus it doesn't hesitate when I accelerate. Thanks for the Lucas High Mileage Fuel Treatment, great job.

Lucas Oil Gas Treatments rock.

Christopher M., Benton, AR

Lucas Oil Gas Treatments rock. My wife and I got a 2009 Ford Focus SE that was a hand me down from my wive's sister that got the car from a used car dealer that abused the poor thing. Engine ran rough as hell. I repaired the engine mounts and that took out 50% of the rough idle. Then I used your High Milage Fuel Treatment with the Safeguard Ethanol Conditioner and that took another 40% out of the rough idle. Now I just have to chase down the other 10% of the idle issue. Since the fuel treatments did such good job on the Ford, I started using the Synthetic Oil Stabilizer with regular fuel treatment with once a year. I use Deep Clean Fuel System Cleaner in my 2011 GMC Sierra. My mechanic is floored every time and happy to see my valves and piston tops are nearly 100% clean. He tells me that is the reason why my truck seems it wants to run like Corvette even though its a V6 full size Truck. But one thing I get from my truck is it gives me a thank you for using your products. I also use your Synthetic ATF Conditioner on top of my factory ATF fill. The ATF is still light red.

The difference is very noticeable

Mike G., Santa Maria, CA

Ethanol fuel regardless of the type has several drawbacks. Two key ones are the loss of horsepower in high outside ambient temp weather and normal cool weather. I have used Lucas's [Safeguard] Ethanol Conditioner about 5,000 after my purchase of my 2005 Ford Escape 4wd/3.0L with 20.000 +K Mi. The difference is very noticeable. There are several steep hills in our area that require you to accelerate up to 4,000 RPM to maintain 65mph. With Lucas I can maintain the 65mph with only 3,000 - 3,500RPM. This now saves a little on the pocketbook on gas purchase. When you use this product plus Lucas's Deep Fuel System Cleaner every 6 months you have a winner for engine performance.

The difference is like night and day! What a difference!

Chris K., Sacramento, CA

I have a 2018 GMC Sierra with a 6.2L EcoTec 3 L86 motor. I tried many types of less expensive octane boosters until I found Lucas Oil Octane Booster. The difference is like night and day! What a difference! I'm hooked for life!

I feel the difference.

Richard A., Miami, FL

I am using Octane Booster with the Shell V-Power NiTRO+ Premium Gasoline in my 2010 Audi A5 and when I drive I feel the difference. Every time I refuel the tank I add 15OZ of Octane booster.

WOW!!!! It Really Ran Great And Helped Me Win Some Events.

BJ T., Park City, UT

Just wanted to say how much I love your Octane Boost! We had some races over the weekend and I used the Octane Boost in my bikes, generators, golf cart and truck (and even weedeater as I cleaned our campsite!) WOW!!!! It really ran great and helped me win some events. My 2 cycle bikes LOVE it and now I am switching ALL my motor oil to Lucas Oil Motor Cycle oil!!! Great products for sure.

After Pouring The Treatment Into My Gas Tank I Started To Feel The Difference

Aidan B., Elma, NY

This product works. After using the fuel treatment for my 2008 Ford, I can feel the effects. My car has 100,000 miles on it and after pouring the treatment into my gas tank, I started to feel the difference. I would highly recommend this product.

Great stuff!

John M., Delta, MS

Great stuff! Use it in my 1990 dodge W-250 pickup Cummings equipt. I’ve got 850,000 km on her and never had to have the injectors cleaned since I started using this product. First used it ten years ago under advice of a friend, never will not use it again, more affordable than “other” products on the market and you know for sure, if it’s got the Lucas name on it, it’s a good product. Thanks for the engineering on this product Lucas!

I have used Fuel Treatment at every fill-up

Michael H., Topeka, KS

Have a F-150 purchased with 35,000 today I have 250,000 and have used Fuel Treatment at every fill-up have only needed to change plugs two times no problems with fuel injectors, actually I have had no problems with any part from the fuel pump to the exhaust system. I still pull my 16 ft. fishing boat to reservoirs far and near. I also still drive to my daughter's house 2,000 miles every year. It's my daily driver.

I will recommend your products to my motorcycle riding friend

Gary G., Baltimore, MD

Recently used your fuel injector cleaner on my 20 year old Motoguzzi motorcycle. I was having problems starting after engine was hot. After pouring a 5 ounce bottle of Lucas injector cleaner in my fuel, the problem disappeared. I will recommend your products to my motorcycle riding friend and continue to use Lucas products in the future, thanks!
