I use this every time I do an oil change. My mileage is at 32k atm, but some gasolines I use aren't always the best. When I don't use Lucas my rpm when going on freeway speeds they sit at around 1,800 but when I use Lucas they drop down to about 1,000 rpm and it saves a lot of gas. Then again I keep up to date with the maintenance and I've been using Lucas since I got the car and this is my daily. **Q: Would keeping this in the car in hot Texas heat be an issue?** A: OF COARCE ITS A DANGEROUS ISSUE !! Storing any flamable liquid in a car is very dangerouse , especially a hot car !! you put yourself at risk of combustion from the heat & also combustion if you get in a accident !! buy a tiny bottle of lucas fuel additive , its about 5.5 oz.s !! fill that up and insulate it in trunk to keep it cool . then when you fill up ? you will have a bottle ready to put in your tank !! instead of hauling around a gallon of the stuff . **Q: Whats difference between this and the fuel treatment 5 oz** A: Their is no difference other than the packaging **Q: Will it help remove P0420 code?** A: 2 bottles of Lucas oil, one gas refill apart, helped with my P0420 Code on Infiniti QX60 engine light. With the 2nd bottle, the light was gone. It worked like a charm. I will continue to keep the fuel tank clean moving forward. Tip : don't wait for the fuel tank to be completely empty before you refill. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Noticeable improvement in engine performance! *by T***D on January 24, 2026* I’ve been using this Lucas Fuel Treatment in my vehicle and the results are great.

I take my review serious *by T***N on January 22, 2026* This a great product that I have been using for years in my 2011 Ram 3500 Cummins diesel. I have no affiliation with this company and this has been a test of time. My truck now has 201,000 miles on it and I have had zero issues with my engine and or any part of my fuel system, this mixture will treat your fuel system, for moisture, raise your cetene levels for more horse power (noticeable), add fuel milage, keep your injectors and injector pumps clean and lubricated, keep your compression brake clean and working properly. NOTE!!! I mix this 50/50 with Marvels Mystery oil about 16oz per 34Gal of diesel on every fill up, well worth the price. ## Frequently Bought Together - Lucas Oil LUC10020 Fuel Treatment - 5.25 Oz, multi-colored - Lucas Oil 10009 Transmission Fix - 24 Ounce, White - Lucas Oil 10118 High Mileage Oil Stabilizer - 1 Quart --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/5573910-luc10020-fuel-treatment-5-25-oz-multi-colored](https://www.desertcart.com.ar/products/5573910-luc10020-fuel-treatment-5-25-oz-multi-colored) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-16*
