That way you get the improved performance, but only have to buy one bottle. That's what I do as I have a 26 gallon tank. **Q: How to use this ? Can I just put this to the fuel tank ?** A: Dump it in the fuel tank and fill it up with gas. This large can will treat up to 20 Gallons. I use it in my motorcycle, so I just put a small amount in. It also has a fuel stabilizer in it which is good cause I don't ride the bike that often. **Q: Does this work in small gas engines?** A: What do u mean by small gas engines? Im running a 1500cc engine and works well with it. Is this small enough? **Q: Does MaxClean come with the application funnel for capless fuel tanks like some of their other products?** A: It does come with a plastic funnel that attaches to the bottle. Depends what fuel your vehicle takes if it will work or not if it's a caplesss filler neck vehicle tho. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Clean *by D***X on 16 June 2021* Everything was as aspected.
