mobil one oil

[Stephen Nordquist]

Finally have 100 hours on my 2003 maristar mcx engine. Would like to use mobil one on my next oil change. Anybody out there using it and do you think its worth the price?

There are several discussions under "Technical", "Engine/Drivetrain", concerning viscosity and types of oil, Synthetic vs dino oils. Enjoy!

My opinion is that you should use what Indmar recommends. There's no advantage to Mobil 1 or any other synthetic oil in this application. AFAIK, there is no Mobil 1 oil that meets the API specs recommended by Indmar for your engine. If you want to use a Mobil synthetic, use Mobil Delvac Super 1300. It is available in 15w40 and does meet the CH-4/SJ specs that Indmar recommends.

That said, only you can determine whether the sense of ... whatever ... you get from using Mobil 1 or whatever is worth the cost. It would probably only cost you, what? ... $5 extra per year?

The brand of oil filter you buy is far more important to your engine's health than the brand of oil you buy.

After reading what BigMac said, "I" think its worth the $5.00 extra a year.....





Now if we were going to discuss the use of Amsoil, it may be worth an added $5.00 a year more than that.... And Amsoil dealers can usually sell the appropriate "good" "better" or "best" filters too....FWIW

What's the Amsoil filter number we need to use?

When I got my boat, it had that crappy Pennzoil PZ-3 filter on it. My oil pressure would run about 20 at idle and hit 40-50 at WOT. When my dealer changed the oil at 20 hours, he put a Mercruiser filter on it and the boat then idled at about 30 psi and ran up to about 60 psi at WOT. When I winterized, I put a Wix filter on and now it idles at 40 psi and runs up to 70-80 psi on the gauge. I'm not saying that this is necessarily an indicator of the Wix being a better filter (although "everyone" says it is), but obviously there's a difference in the way these three filters interact with the lubrication system. I have concluded, rightly or wrongly, that it means the Wix is better.

I'll see if I can find a dealer and have them crossreference it for you.....

Lubricant – Indmar uses and recommends
Pennzoil 15W40 Marine Oil for use in all of its
engines. If Pennzoil 15W40 Marine Oil is not available,
any 15W40 motor oil meeting the API ratings
of SL/SJ, CI-4, CH-4, CG-4 are acceptable. See
Chapter 6, Maintenance, for information regarding
the use of synthetic oil.

From Indmar's site on the MCX.....

Yeh, they also recommend the Pennzoil PZ-3 filter, so I'm guessing that they've got some kind of marketing hook with Pennzoil/Quaker State.

Synthetic Oil
Synthetic oil that meets our requirements of 15W40 and
API SL/SJ/CI-4, CH-4, CG-4 is acceptable to use after
100 hours of operation with the recommended oil. The
use of synthetic oil does not change the requirement of
50 hour oil change intervals.

Here we go again. My thought is Synthetic can handle higher temps period. Anyone ever pick up a weed in the strainer? How about a chewed up impellor. As your temp rises and you are worrying about boats, skiers or what have you what would you want in the crankcase? I respect BigMac and his opinion as he definately knows his crap, period! If you feel more comfortable from a history of using synthetics I would go for it. If you have had favorable results with the dino juice follow BM and Indmar's recommendations and change often as it is cheap maintenance. I use synthetic as my ride was delivered with synthetic. I use synthetic in everything including my lawnmower. I still change as often as recommended.

Funny thing is, so do I and don't use it.....
