Lucas Oil 10020 Fuel Treatment - 5.25 Ounce (Pack of 6)

Been using this fuel additive for the last 12 years can really see and hear the difference when not used I do get a mileage increase with the increased fuel mileage, I believe this product pays for itself. But also, the engine runs smoother, I use it in both gas and diesel engines and in diesel engines, it makes it so much quieter I also added to fuel that I leave in fuel cans the only downfall to this product is if you use more than what is recommended as I used to do It would foul out spark plugs sooner than needed. But that was my fault, not the product I would highly recommend this product works great in older engines with high miles also very effective in both carburated and fuel injected engines

I can’t say enough about this stuff. 3 bottles and it fixed a long cold start crank issue in my 2004 Acura TL. Currently I am running it in a 2005 Camry with 160k on the dash and let me tell you….. you can hear and feel difference immediately after putting this in. Car is instantly quieter, smoother, has more power, and gets better mpg.You must run three bottles in three full tanks back to back on your initial run to achieve total cleaning. After that, you’ll really notice it when you don’t put it in.Use one every tank!

I give this 5 Stars. Having just loaded into my Mercedes and Chevy Trailblazer. Because all the reviews I've read. This is a very highly tested and rated product. As with any other Lucus product. I have no doubt this will live up to the high standard of all Lucus products. Not to mention the Great Price For A Product Of This Quality.. Vehicles are under 35 Thousand Miles.. So I didn't need a Super Harsh Fuel Treatment.

I toss a little in every time I'm doing my 5k or six month maintenance. I've never noticed much of a difference with lower mileage vehicles, but I've seen good enough results with high mileage vehicles that I figure it definitely can't hurt. Things like better mpg, engine running more smoothly, etc. Super easy to just put a little bit in the tank and one bottle lasts a really long time. Fuel injector cleaner is also listed as an optional maintenance item for my car, so....

Ordered and got next day. Saved a trip to the store and saved a little money. Use at every fill up of ⛽ to keep injectors clean. Buy this product all the time, first time buying online. Will buy again. Lucas products are awesome 👍

Purchased this product for my 1987 corvette. My mechanic said it good for vehicles that are not used much on a daily basis to help keep engine parts clean ..

Awesome product. Have a 200k mile 2005 Grand Marquis that I use for grinding miles that was starting to run rough at idle, then at 25 mph, then 35, finally 45. Put 1.5x recommended dosage and now idles smoothly within the first 10 miles of using the product. Highly recommend.

Seem to get almost 1 extra mpg when I use this. All the good they say it does is a bonus.
