## Questions & Answers

**Q: lawnmowers is this good to keep the system clean while using it and not just when storing it?**
A: I've been using it in all the fuels for my mower, 2-stroke mixes, and my motorcycle and all three have been surprisingly clean, especially the two stroke motors.

**Q: Is this to be used prior to an oil change?**
A: If it's like 500 miles before an oil change, that's OK. You can also use after an oil change, but TECHRON recommends NOT to use more than twice during a new oil change. I use during the last 500 miles (whole bottle) on near empty tank & run the car until the reserve light comes on. Been using this for at least 20 years. 

If the car runs rough, you can pour in a bottle twice, like every 2,500 miles, or repeat the process, whichever you want to do. For best results, try & do as much highway driving after pouring in & make sure to drive at least 5-10 miles to get it up in the lines & all before turning the engine off. Since you're going to be at the gas station & pouring in before refilling the tank, this is a good time. Good Luck!

**Q: What is the ratio of additive to fuel? Can it be used in nonethanol fuel?**
A: 1 oz per 10 gallons.  It can be used in nonethanol fuel.

**Q: Can you reseal the 20 oz bottle and use the rest later?**
A: You can't physically reseal the paper tab, but yes you can screw the cap back on & it will keep it sealed for later use. However, this will not guarantee the same 5 year shelf life.
