The Gumont Multi-System Tune-Up came in a container similar to SeaFoam and looking at the indication of use I realized it was basically the same thing just with a different packaging (even the bottle is the same dimension and closure system). I've used SeaFoam system tune-up before and was not surprised that the same results was noticed when using Gumont Multi-System Tune-Up. In my 2012 Toyota Highlander I noticed an improvement of 0.2 MPG driving 60/40 Highway/City with an average 21.1 MPG combined overall (semi-lead foot driver). These findings were observed after 3 fill ups and it's been staying consistent. I maintain a regular oil change interval of 5k miles and currently with ~32k on the odometer and did not have an issues previously so I can not tell if this would help with anything other than the slight MPG improvement. Price wise it is about the same as SeaFoam. Overall this product does help minimally with MPG but nothing dramatic. I haven't noticed any decrease in performance or problems so I would have to say as a system tune-up it is reasonably price and if it does what is stated on the packaging not a bad deal.

It actually did seem to increase the MPG of both my parents cars (which get about 20 MPG on average) by about 1-2 MPG. Will not save a ton, but still worth a try.

I have a 2006 Roush Mustang Stage 3 with about 40,000 miles. Decided to try out the Gumout Octane Booster one day and loved it, then I discovered the Gumout Multi-System Tune-Up and couldn't be happier. Engine runs smoother and accelerates better. Will definitely use on my other vehicles!
Bottom Line Yes, I would recommend this to a friend

Comments about Gumout Multi-System Tune-Up:
I love how kind and thoughtful a tune-up can be with just one bottle of GumOut. I thought it wouldn't be enough but instantly after three miles I noticed no tings and smoother acceleration.... all without a smoke screen!

Comments about Gumout Multi-System Tune-Up:
I have a 1995 Chevy box truck that I keep around for our business, but that we don't drive on a daily basis. Anyway, it dies in October on a customer's premises, and I got it going just enough to get it back to the office, where it then sat. Winter came along and I did not feel like working on it. Anyway, after the ice melted, I got to it, and had to put in a new distributor. While taking the fan shroud off to be able to see the timing marks on the pulley, I broke the heater control valve. So, I went ahead and replaced that along with all the heater hose and while I was at it the upper and lower radiator hoses. SO - after all that - fire it up, set the timing, and it was still running rough, probably from the old ethanol gas. No problem - I put a bottle of Gumout Multi-System Engine Tune-up and let it run for a while. The rough running stopped, and just in time for our spring heavy truck use season! I am not sure what they put in there, but it sure worked for me!
Bottom Line Yes, I would recommend this to a friend

Comments about Gumout Multi-System Tune-Up:
Used this product in my 2004 Mazda 6 with 220,000 miles on it. First impression was that I believe the throttle response was a little better. Most of my driving is stop and go in the city to and from work. I measured 1 additional mpg on the tank of gas containing the additive. Not sure if subsequent tanks of gas will show the same gain but I'm going to be watching. Overall, I would purchase again and use every few fill ups.
Bottom Line Yes, I would recommend this to a friend

Q:
I bought my 2010 1.8 liter 4-cylinder engine at 20,000 miles and now have 30,000 miles. I have used STP gas treatment and Lucas fuel treatment. In the past I have been advised to use these products once a month. I am interested in this Gumout multi-system tune-up. Do you think it is a better product since ethanol is added to gasoline? How often should it be added to the gas tank?Asked on 5/29/2015 by Alicia from Florida1 answer
CUSTOMER CARE
A:
Happy to answer your question Alicia! Ultimately it will come down to personal preference, they will all function generally the same, and more customers go with the Gumout or Lucas. It seems like Gumout would be better formulated for more applications. It's generally recommended to do a fuel system service every oil change but it can vary depending on the manufacture's recommended service intervals.Answered on 5/31/2015 by Panda from AAP
Q:
After adding to the crankcase do i let it circulate for 10 minutes and then drain the oil, or do i drive it for 100 miles or so and monitor the color of the oil? Basically is it a 10 minute engine flush or a "leave in" engine cleaner? Thank youAsked on 2/24/2015 by J-Bo from Logan Ohio1 answer
