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.
Review: A hopefully good way to make amends for my non-top tier gasoline sins, and brought my riding lawn mower back to life! - 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!

## Questions & Answers

**Q: Does it have to be poured in the gas tank on a nearly empty tank?**
A: Yes,Add entire bottle to nearly empty gasoline tank at time of oil change. Refill tank with 18 to 35 gallons of gasoline. Do not refill tank until near empty. Repeat every 3,000 miles at time of oil change. For small engines, add to gasoline using 3/4 to 1 ounce per gallon of fuel. For small 2-cycles engines, add 2-cycle oil as recommended by the engine manufacturer.

**Q: Is this better than spraying carb cleaner directly into a lawnmower carb?**
A: Never thought of putting it in a lawn mower. This is an entirely different process than spraying. Adding this to the gas produces a continual cleaning process of removing gums and schlacs in the ports, channels, etc. Spraying is a topical treatment that provides limited cleaning only when you spray. If I was going to use it in the lawnmower I’d put a couple tablespoons in the tank each time I filled it until the can was empty. Interesting idea. Worth a try I suppose! 4 cycle only!!!!

**Q: Can this be used in a turbo engine, as far as in the oil?**
A: Not sure what people are saying not to use this or any treatment in the oil. It's a petroleum-based product, of course it can be used in the oil. Even states that on the bottle. I wouldn't use it all the time in the oil, but adding something like Seafoam etc to the oil at the end of the oil cycle, about every 25-30k miles (3rd or 4th oil change) has been shown countless times to clean out the gunk in the system that can cause bad flow and blockages and free up sticky valves and lifters that even a fresh oil change with the best oil cannot do. 

This product is mainly formulated for fuel systems though so that is its key advantages. If you want a good oil additive, use Seafoam. Stuff works wonders in the oil, esp on older, less maintained engines. With a turbocharged engine, you definitely want to add an oil additive every 25-30k miles more so than an NA engine. This is because the oil passages feeding the turbo are a lot smaller and more susceptible to blockages and flow restrictors than the rest of the common components inside the engine itself.

**Q: Will this work on a riding mower?**
A: Sure. Any four stroke gasoline engine. All engines develop a gummy, shelack build-up after long use. If you are having a problem with the mower fuel system I’m wondering if that’s the real problem. Takes A lot of gas to gum-up a carb but it could be though. It will take quite a few running hours to flush an entire can through the fuel system at the recommmeded rate. Would be worth a shot. Good luck. (Only add to the fuel!!! Never to the oil!!!)

### ⭐⭐⭐⭐⭐ Excellent value and great for high pressure fuel pumps
*by S***R on July 13, 2023*

I recently had the engine and transmission mounts replaced in my 2006 direct injected Audi 2.0 turbo car at 218K due to idle vibrations and decided to tackle the gas fumes I had been experiencing over the past 5 years in my car while backing up. I tried Liqui Moly Jectron for a week then I came across the DI Jectron version for direct injection engines on the Liqui Moly website I tried the next week. The gas fumes changed from a gas smell to like a sweeter smell with the DI Jectron but on the last 1/4 of tank I got a P0171 code while having to slow down to about 45 mph on a mountain in traffic and then accelerating back up to speed slowly. After clearing the code and adding the Gumout Tune-Up the next morning I tried to duplicate the issue in the same area for two days on the way back from work and the code did not come back. I also noticed less friction in the fuel system with the Gumout product while slowing down and accelerating so I may have has some gunk in the system after the car mostly sat for 2 years during COVID with the ethanol fuel we have in California. The Gumout Tune-Up also cleared up the gas fumes as I am not smelling it anymore and the car is running almost like new. I will continue to use the CRC intake valve and turbo cleaner spray or the Gumout Tune-Up to clean the valves before oil changes and the Gumout Tune-Up every 2 months for the fuel system as I believe these high pressure pump systems need some kind of lubricant in them with the ethanol in the fuel. I may also use 4 ounces of Marvel Mystery oil in the tank again on regular fill ups like I used before COVID to keep the system lubricated. Gumout makes a great product at a great price. ***Update the gas fume smell came back on the 3rd day of Gumout, I am going back to the Liqui Moly DIJectron.****
