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.

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!

Lucas Fuel Treatment is an awesome product.

Randall B., Comanche, TX

I have used this in all my vehicles. So, I knew that it was a quality product. Recently, my son had trouble with his lawn mower. He had let it set over the winter with gasoline in it; unfortunately, the gasoline contained ethanol. When he got ready to use it again this year, it would not start. We emptied the gas out of the tank. We replaced the fuel filter and all the fuel line hoses. The carburetor is complex, so we did not mess with that. We finally got it started, but it ran rough and it only ran at an idle speed, even though it was full throttle. We contacted our local small engine repair shop. We were told that this often happens if you let an engine sit for an extended period of time with ethanol fuel in it. We were told that the carburetor would have to be rebuilt and that would cost about $1,000. Instead, we decided to try the Lucas Fuel treatment. I checked the website, and it said that overtreatment would not harm your engine, so I put the whole 5.25 Oz bottle into 5 gallons of fuel. We put new fuel in the lawn mower and started it. After five minutes, it started running smoothly, but still at a reduced speed and it was smoking badly. After 10 minutes, it was running at normal speed and all of the smoke was gone. It would appear that this fixed the carburetor problem and saved me $1,000. I learned 2 lessons from this. First, never use gasoline that contains ethanol in a lawn mower. And, second, Lucas Fuel Treatment is an awesome product.

Really has made a difference in the performance of the engine

Gordon W., South Burlington, VT

I have been using your upper cylinder lubricant in my 2014 Camaro since it was new. Really has made a difference in the performance of the engine. Not to mention that it helps keep the intake, injectors and the valves clean. One of the best things you can do for your engine. Lucas products are the best out there and a great value too.

After 30 Miles The Rough Idling Subsided

Henry G., Lawrenceville, GA

At 65 years old not much surprises me. I have NEVER used additive in an auto. I have a 2012 Hyundia Genesis with 209,000 miles. It was idling rough. I'm thinking I need a $300.00 cleaning at the dealership. I decided for once in my life I would try an additive. I went to Walmart and of course they had 50 different kinds. I pick LUCAS because they are very reputable company. OK let get to the meat of this story. I put 6 oz of LUCAS UPPER CYLINDER lubricant in my tank. My hand on a bible after 30 miles the rough idling subsided. I would not believe this if it had not happened to me. Jaw dropping moment.
