## Questions & Answers

**Q: what is the shelve life after opening the bottle ?**
A: Check the date of expiration on the bottle label, first.  Usually, sealed 2cycle oil has a shelf life of about 5 years. Once opened, you should use it before second season, about 24 months.  I suppose that has something to do with the petroleum distillates and evaporation?    That’s as far as my knowledge goes.

**Q: So, how many bottles are included at this price and how many fluid ounces are in each bottle?**
A: Lol, really? This only shows one bottle, so it's for buying one bottle. Glen is kidding...

**Q: Is this good for mercruiser 3.0?**
A: Yes , it is the best on the market.

**Q: We just received this….. did they change the  packaging? It came in a tall round bottle.**
A: Did you order from our store? Or from Amazon?
If you ordered from our store, please contact us with an order number.
The packaging did not change, Mercury/Quicksilver has both options available: a 12 oz bottle and also a 32 oz (like the one in the picture)

### ⭐⭐⭐⭐⭐ Read the reviews - This Stuff Works!
*by Z***N on October 9, 2024*

Our 75hp Mercury outboard hadn't been run for a over a year. Prior to that it just didn't seem to have the power it should & also sounded like it had bit of an intermittent miss. I read through some boating forums and saw the high praises for this product as being better than the Marine Seafoam. It is made by Mercury so figured I didn't have much to lose and everything to gain. On the recommendation to "shock" the system and clean the fuel system and de-carbon the power head properly, I used a 3oz. to one gallon ratio. I had a small portable 3 gal. fuel tank and once on the lake I switched over from the onboard boat fuel tank to the portable. Almost instantaneously I could tell/feel the difference with the motor....seriously, scouts honor! I continued to run out the small tank varying throttle positions at times. When done with the "shock treatment" the motor was back to running smooth & powerful as it should. Made our fishing trip in MN a pure joy. I'm a firm believer now and will always use this additive as directed for sustained maintenance whenever fueling up. PS....don't forget to add a quality fuel stabilizer as this product does not contain those pertinent ingredients. Fish on.
