2016 Merc 250 pro xs motor oil.

[BassinBrian]

I’ve always run Merc DFI synthetic oil in my motor. Is there any price friendly oils that are comparable? Don’t want low quality low price. It’s getting expensive at 30 bucks a gallon though. I’ll burn a tank of oil to a tank of gas 52 gal. Any help appreciated.

DFI I meant...

I think it is a synthetic/mineral blend.

2 gallons of oil to 52 gallons of fuel sounds a little excessive, I could be wrong though. Look around and see if any dealers near you sell DFI in bulk, that will save you a couple bucks. FWIW, I've never run anything but Mercury DFI oil but if it was an emergency I'd run Mercury Premium Plus in a pinch.

If you would, please take a moment to review the Announcements at the top of the Forum, and be sure to provide the Required Info (serial number) when posting. Thanks!

Most of these engines have a 3 gallon oil tank... It would be very unusual to be burning that much oil (though not impossible, especially if you're doing a lot of holeshots and/or hard acceleration increases, which instantly add a 50 shot oil pump count).

I can tell you I run 2 pro xs 250's one on a 521 other on a 522 and I have never ran DFI oil and never will. I tear down a good number of these engines and all that are run with DFI are the worst. Much better oils out there.

What do you use?

Eastenfish... I would strongly recommend running the correct/recommended oil. You were on the right track to start with... if you really want something for oil that's "creme 'de crop" then use the Mercury RACING oil.

Oh I do. I use DFI and cocktail. Just curious what he thought was better. I used klotz for years in my 2008 150 optimax without any issues. But switched over when I got my new to me boat.
