When the order arrived I was sent 3, I immediately called and they said it was an error and I received the other six gallons 1 week later. I hope this helps. Tim **Q: Description indicates 2.5 gallons. Is this correct?** A: Based on historical price this sale is a 1gal jug. In my experience Quicksilver DFI Oil is sold in 1 gal and 2.5 gal jugs. I have purchased the 2.5 gal once or twice but I seldom see any discounts on the 2.5 and usually find the1 gal jug available at a discount and buy 3 at a time. The 1 gal jugs are cheaper per ounce then the 2.5. **Q: Can i use this product for seadoo jet ski di 2002 (direct injection jet ski)? seadoo recommends fully synthetic api-tc compliant oil** A: If you use gasoline as your fuel, then yes it’s a fuel treatment for those that use ethanol based fuels and stabilizes fuel for storage purposes. **Q: Can i premix 50.1 ?or is just for engines with dfi** A: Dfi only. Do not mix! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best price and fast shipping. *by J***N on October 10, 2024* I shop around for this DFI oil because it has gotten pretty pricey over the years.

I'm very satisfied and purchasing now for a second one.
