I had mixed feelings about this product. It cleaned my fuel system alright, but pouring it out of the bottle was tricky—it spilled a bit. I wish the bottle design made it easier to control. The 6-pack is handy, but the pour could be better.

Great for older vehicles!
I've been using Gumout's Regane High Mileage Fuel System Cleaner on my 2005 Honda and the improvement is noticeable. My engine runs smoother and I've even seen a slight increase in gas mileage. The 6 oz size is perfect for my needs.

Decent product, but a bit pricey
This fuel system cleaner does seem to clean my system well, but I feel like I can find similar products for less. I bought the 6-pack, and while it's convenient, I wish it was more cost-effective. Good cleaning results, though!

Didn’t work for me, unfortunately
I was really hoping this would help my car, but I didn’t notice any difference after using Gumout. Maybe my car is too far gone? Didn't have any issues with delivery, but the results were disappointing.
