Review: Perfect tune up in a bottle for most vehicles! - I’ve been really impressed with the Gumout Multi-System Tune-Up. After using just one bottle, my engine felt noticeably smoother, with better throttle response and quieter idling. It does a great job cleaning the entire fuel system, helping remove carbon buildup from injectors, valves, and combustion chambers, which makes a real difference in performance. I also appreciate that it helps improve fuel efficiency and protects against corrosion from today’s ethanol-blended fuels. It’s incredibly easy to use — just pour it into the tank and drive — and it works on cars, trucks, and even small engines. For the price, this product delivers excellent results and is a simple way to keep your engine running strong and clean.

## Questions & Answers

**Q: Did the formula change? does this no longer contain pea?**
A: Per ITW Global Brands response 7-17-23, "Multi-System Tune Up fuel additives contain CarbonClear which is the most advanced P.E.A.  All our Gumout fuel additives contain equal parts PEA."

**Q: Is the shipping time of one to two months accurate?**
A: I don't know. It would depend on the seller. Seems like a long time. Walmart delivery is like two days.

**Q: How often do I have to add this product to my vehicle’s gas tank?**
A: Add it in every 2 to 3 fill-ups. It will probably take six months or more before you start noticing a difference. But, your gas mileage will improve, and your engine will run smoother. Just give it time. I went from 12 to 13 miles a gallon all the way to 18 to 22 miles a gallon today. It works!

**Q: How often can you use this product?**
A: I've been using is for many years. First time, put an entire can in your fuel tank when you fill up. After that, I put about 1/3 to 1/2 with every fill up. I use it in my tractors, mowers, gas leaf blowers and edgers and boat. Since the boat sits up all winter without running, I usually put 3 cans in the tank the last time I run it. In addition to cleaning the entire fuel system, it also stabilizes the fuel so it doesn't break down and turn into lacquer. Also, if you buy fuel with ethanol in it (most gas has 10-15% ethanol in it), Gumout helps keep it from turning into a gel like substance in your fuel line. Ethanol comes from corn and soybeans, so if you leave it in fuels line without a product like Gumout, it can set up fuel related issues. Hope that helps!  Eddy

### ⭐⭐⭐⭐⭐ A hopefully good way to make amends for my non-top tier gasoline sins, and brought my riding lawn mower back to life!
*by T***N on February 27, 2018*

I had heard about this stuff from the Scotty Kilmer channel and Engineering Explained on YouTube. I have recently been on a spirit quest to do excellent preventative maintenance on my 2007 Nissan Altima 2.5 S now that I am using it for Uber and Lyft; driving about 1000 miles more a month than I used to. I read recently about the Top Tier rating system for fuel products and I realized with a sink in my stomach that for the past 37000 miles, I have been filling up at the Pilot gas station that is five minutes away from my house and it is a non-Top Tier station. My car had had no problems with the engine or fuel system and still hasn't (knock on wood), but regardless I wanted to do something to try to correct 37000 miles of the gasoline sin of using non-Top Tier gas that lacks the amount and quality of detergents that your Top Tier stations like Shell and Chevron have. I drove my car to nearly empty and pulled into the Shell gas station nearest me. Given that I have a twenty gallon capacity tank, I dumped the entire bottle of the Gumout into my fuel tank and added a fill of gasoline–17.86 gallons–on top of it to mix it in as the instructions said to do. I then drove my car to nearly empty with the Gumout/Gas mixture and just did my second fill up with only a Top Tier gasoline. Because my car had no problems like rough idle, slow acceleration, or what have you to begin with, I cannot say I have "noticed" any difference; but that doesn't mean there wasn't. For seven bucks and being approved by many reputable mechanics, I don't think my money was wasted and now that I am using Top Tier gasoline only I feel better about the longevity and reduced need for repairs my car is hopefully going to have. In summary: My car didn't have anything noticeably wrong that would allow me to observe a noteworthy improvement, but it didn't hurt my car either as far as I can tell; and it has the right cleaners and such for modern fuel injected vehicles. With that uninspiring part of my review over, I can now get on to the really cool NOTICEABLE benefit this stuff had: it was the Dr. Frankenstein to my mower that had been sitting unused too long! I went out to the ranch I manage to do some mowing and to my disappointment, the mower was dead and would not even start. I replaced the battery and was able to get it to start, but the idle was extremely rough and within a minute it spluttered and died. Noticing that the tank was maybe only 10% full, I went and got five gallons of fuel and added about 5 ounces of Gumout as per the instructions for four stroke small motor gasoline. I filled the mower up, shook the mower and let it sit for a minute, went to start it up, and COUGH PUTT COUGH PUTT COOUGHH VROOOOOOOOOOOOMMMMM!!!!! That baby coughed whatever gunky fuel and deposits had clogged up the fuel line or something and fired up! It ran smoothly from startup to intentional shutdown and I knew that I had the Gumout to thank for that. A further benefit of the Gumout too is that it is apparently a fuel stabilizer, so the other 2.5 gallons that is going to sit untouched in the can for up to four months is going to be good to go! All in all, I am pleased with the stuff. Be an educated purchaser: do your research and make sure it is going to be correct and useful for your application, but sometimes it is just fun to use "snake oil" type items like this and just see what happens (when they have been approved for safety by the appropriate agencies when used according to instructions, of course). Thanks for reading my review, I hope it helps you to make your purchasing decision!
