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) ## Frequently Bought Together - Quicksilver Quickleen Engine and Fuel System Cleaner - Quicksilver Quickare Fuel Treatment - Quicksilver Quickstor Fuel Treatment and Stabilizer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/70729827-quicksilver-quickleen-engine-and-fuel-system-cleaner](https://www.desertcart.no/products/70729827-quicksilver-quickleen-engine-and-fuel-system-cleaner) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-12*
