## Questions & Answers

**Q: I put it in with a half tank still in the gas tank then filled up will that effect how well it works?**
A: This Rislone stuff works REALLY well, especially if you've never used a fuel system cleaner to clean your fuel lines & intake. To get the maximum cleaning effect, you should run your tank down to 1/5 of a tank, and THEN put in the whole bottle and drive your car around until you get down to only 25 miles left and THEN, fill up to ONLY a 1/2 tank. This is my only "system" and it's not what they say to do on the bottle. In essence, when you put the bottle in, with 1/2 a tank and THEN, filled up.....you just diluted the strength of that 1 x bottle, by adding all the extra fuel. Try doing what I suggested and it will clean your fuel lines out very very well plus any carbon buildup within your intake or combustion chamber. Good Luck.

**Q: How does this work in a 2 stroke outboard boat engine?**
A: Thank you for your question, and for considering using Rislone Gasoline Fuel System Treatment (part number 4700) in your 2 stroke outboard motor.

**Q: Do you pour in the whole bottle? I have a 1998 vw jetta 2.0**
A: Yes the entire bottle

**Q: how come i was charged tax on a fuel treatment additive being sold by amazon...but not on  other items being sold by other sellers**
A: From my understanding it’s because the seller is in your state. When you buy product from seller or of state there are no taxes. That’s why the government is trying to pass new laws to be able to tax the products.

### ⭐⭐⭐⭐⭐ Better than expected
*by L***. on January 19, 2025*

I purchased this product a couple of times now and I'm really pleased with its quality that it brings to my gas mileage and the smoother my engine sounds. I've used other treatments that were lower in cost which are considered good however this product is a bit pricey to be purchasing too often regardless of its performance which is great. I would prefer this product overall when it comes to performance, functionality, as well as speed just can't really see purchasing too much. I do still have leaks but products can only do so much depending the problem
