## Questions & Answers

**Q: my tank holds 33 gallons, would i have to fill it up only will 20 gallons after i pour in Max Clean or could i fill right up?**
A: Put in a bottle & fill your tank 3/4 of the way up.  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.
