## Questions & Answers

**Q: Can you use Quickstore fuel treatment for normal use even when boat is being used regularly?**
A: It would be a waste of money to use this in a boat being run regularly. It is made to protect engine parts during long periods of storage. It would not hurt anything, but is just money wasted.
I would recommend using Mercury QuickCare, it keeps fuel fresh for up to 30 days, and prevents corrosion of engine parts, that can be caused by ethanol in the fuel, also you may want to additionally use  Mercury QuickClean , this product  cleans the carburetor , fuel injectors, valves , and plugs  as you are running the motor.

**Q: How much fuel does 12 oz. Treat?**
A: I put 2 ounces to 12 gallons but recommendations might be different

**Q: What's the difference between this and the Quickleen?**
A: Quickleen is used to prevent carbon deposits. Quickcare is used to prevent ethanol separation. I use both with every fill up!

**Q: Can I use quick clean and quick care at the same time in my tank simultaneously in my OptiMaxx 135 outboard motor**
A: I use all 3 at the same time.
