Gumout510014 Regane Complete Fuel System Cleaner, 6 oz. (Pack of 6) (510014W-6PK)

Awesome product. I use it all the time. I've been buying it here for about four years. Found the exact same item at a local big box. Auto parts store for a lot less. Highly recommend it.

I have a 2002 Chevrolet Silverado with a 5.3L engine. I have never had the injectors cleaned. My usual mileage was 13 city and maybe on a good day 17 highway. I put two bottles in the fuel tank and started noticing a difference in performance and fuel economy within the first 100 miles. The highway MPG increased to almost 19.

Best cleaner on the market especially for the price! And definitely does contain PEA 💪🏽💯

As a retired auto tech I use this to help keep fuel system clean in our vehicles. About every 2000 miles. Also add it to a tank of gas on fill up if vehicle is going to sit for awhile as we live in an area that gets cold and can generate condensation in fuel tank.

My prius was using a ton of oil (250,000 miles). My mechanic told me it was a goner. When i read up on it i found out prius' oil ring gets gummed up and the only thing that will reverse this is a gas additive with "regane". A couple bottles later and 25,000 miles ago my car uses 1/4 qt of oil

Purchases 2x cases of this for a Turo fleet. Additive is poly ether amine, (pea). Beware: the instructions say to pour this into a nearly empty tank and promptly fill up.I erroneous assumed this was a suggestion to help the detergent work by using fresh gas with minimal water contamination. However, there was a second reason of which I was unaware (it seems obvious now, but I do with the instructions explained WHY to do things, for better product education).I violated the instructions, pouring it into a Mercedes ML350, and did not top off with gas. Little did I know, Benz uses a bunch of complex plastic pieces in the gas tank neck, bonded together with plastic adhesive.The adhesive appears to have been dissolved by the ether, the residue sitting in the tank neck allowed to pool at the seam until it was compromised, throwing an evap leak. I bought a smoke machine and discovered that I probably caused this issue via lackadaisical adherence to the instructions.Lesson for me, contained in no literature: Concentrated poly ethers may dissolves plastic bonding agents used on Benz vehicles.

At my most recent oil change, the dealership suggested a fuel injector cleaning to the tune of $200. I didn’t have that, so I put it off- and a couple weeks later, I noticed my car was driving a bit rough and the check engine light came on. I figured even if this didn’t solve the issue it was worth spending $6 to see if it would make a difference. I poured it in my almost empty tank right before filling up, and 3 days later, I started my car and the light was off, and it ran like a dream.

Fast shipping. Good seller. Irritating that prices continue to creep up and containers get smaller.
