Gumout 510014 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.

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

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

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.

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.

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.

Our 2004 Durango had issues. The check engine light had been on for many months, and the code indicated an O2 sensor was the issue. But it still ran fine, and since we didn't use it that much, we never replaced the O2 sensor. But then the Durango started running rough. When it first started, it idled rough. When going slow and steady it usually ran ok, but any demand for more fuel, like accelerating or going uphill, and it would miss like crazy. The Durango would also shake and you weren't sure if it would keep running or not. The check engine light would also flash during this time. So we started thinking about where we were going to take it to get it repaired. One day I decided to try a bottle of this Gumout fuel system cleaner. The first couple of trips still had the same missing issues, but then it gradually started to get better. (These were all short trips to the store and back so it took a little longer to work). But then one day the car started up and idled just fine. It accelerated just fine, and the check engine light was out for the first time in months! From then on, the Durango never missed again, and the check engine light never came back on. The old Durango now runs as well as it did when it was new! I don't know how this stuff could even help an O2 sensor, but apparently it did. I have since put a second bottle in the car, and will order another one just to have on hand. This is a great product that really works! In our case, it was a miracle in a bottle!

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