I normally get about 53mpg on both highway and city. After I am now getting 60mpg on my 40 mile trip to work. That's even using cruise control as well. I was skeptical at first but now I'm a believer. Can't wait to see what I average going to Las Vegas in 2 weeks. This is definitely worth every penny. The pick is when I got to work, I never hit above 53 going to work and I drive the same route 5 days a week. ### ⭐⭐⭐⭐⭐ It Worked for me........ *by J***. on September 11, 2016* I bought this after I became the owner of a 2001 Dodge Durango 4WD with a 4.7L engine with 155,000 miles on it. The 4.7L engine is infamous for its knock and valve slap noise. In my case loud enough to compete with the radio. After tons of research I came across some reviews of the BestLine brand of products. I figured for less then $20 I might as well try it.I changed the oil and added 2 quarts of BestLine with 4 quarts of a good high mileage oil and the valve slap was reduced by more then 50%. I now have to intentionally listen for the valve slap to hear it. Look at some of the online video reviews and then spend the money to give you some piece of mind. For me, the vehicle was a gift from my son so I wasn't out anything, but I couldn't stand the noise. I now use this as my primary get around vehicle and with 168,000 miles it is still going strong.It's a minor investment for the piece of mind it brings. I am a hard skeptic on most things but I am a believer in this. I am trying the gas treatment now and will see if it improves mileage or makes the engine run any better. --- ## 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.gr/products/11062177-853796001955-engine-and-gas-additive-kit](https://www.desertcart.gr/products/11062177-853796001955-engine-and-gas-additive-kit) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-04*
