Recommended Oil

[mparker2997]

Ok. I am confused. Please chime in. Based on reading the forum..I am using rotella t diesel 15w40 as it seems to be highly recommended. My friend was told it would void warranty by our dealership. The dealership recommended 20w50 valvoline premium. This seems to totally ignore the manual.

Question 1
Does using RotellaT diesel 15w40 void my warranty?

Question 2
The valvoline is not 15w40 and it does not have a rating per the manual. Seems like this one would void the warranty!

I would get the pennzoil if it was available but nobody has it. Not even the dealership. Seems like such a simple thing would not be so complicated.

I think you're OK with the Rotella.

[mparker2997]

Thanks but thinking I will be ok is not good. This is a simple thing that the manual and dealerships should be "crystal" clear on.

Yeah, what would I know about the warranty anyway?

Why don't you call SC customer service tomorrow?

Your Indmar Owner's Manual has specifications that an oil should meet at a minimum. Get ANY oil that meets that minimum spec and you are fine. There are laws that protect you as long as you meet the minimums that the manufacturer sets.

You can download the manual if you don't have it.

I think I will. Thanks. I thought maybe a moomba or indmar rep would also chime in.

No way, man! I wouldn't risk it. You'd hate to have an engine failure and then have them send the oil out of your motor off to their lab for testing and they find out you were using Shell, Castrol or, God forbid, Quaker State oil.

Thanks. That's the way I see it but that's not what the dealership is telling me.

Yup, I did the research 2 years ago and that's all I've ever used. That is also about the only 15w-40 you can readily find around here.

[JeffCook3]

I am that friend Mike was talking about. Bottom line is this... I know a lot of guys are using the Rotella, but the service manager and sales guy is saying not to use it. However what they are saying to use doesn't meet the specs in the manual. Calling SC tomorrow to see what they say.

I couldn't find the Pennzoil anywhere locally so just ordered it.

I can't figure out what that says. How about a link to the page on the turbodiesel site with the info you are trying to quote?

Sorry, those are very old screen shots that look fine on my phone.

And obviously the best way to see how well your oil is working is to have it analyzed.

[kaneboats]

I'm not sure the analysis for diesel engines in the articles would be the same for a gasoline marine engine.

[zabooda]

You need to check the certifications. Everyone using the high performance dirt bikes have gone to Rotella T and it is labeled for motorcycle use.

I had this same issue a couple weeks ago at the Lake of the Ozarks. It was the first time I needed to add oil and I figured I'd just beebop on over to the marina and pick up some Penzoil 15w40. No dice. No one carries it. So then I went to just any 15w40 but back pedaled when I realized most 15w40's are diesel oil. I run Mobil Delvac in my Duramax. I started reading as much as I could find before I dumped it in the LSV. There are equal parts information on NOT running diesel oil as there are FOR running it. What I found was for that much disinformation, I wasn't going to chance screwing up my motor. I called 4 separate marinas and spoke with their techs. All of them, told me not to run any type of diesel oil as it had detergents that could harm my motor (5.7 GM block/Indmar). They all independently told me to switch to any marine or racing oil with a 25w40 rating, stating that all Merc stuff had switched to it.


That's my .02¢ but there are a ton of forum members here, and on other sites that have been running Rotella for a long time with no issues.

That's why I look at the lab analysis if the oil out of the bottle and pick what's best for me. In the end I doubt it will matter. I apologize that my screen shots are blurry when posted via taptalk. I hope the links at least provide pictures without being blurry. Again contributing to an oil thread is always a double edged sword. I don't expect to sway anyone to any particular brand.

[mparker2997]

Jeffcook3 called SC and Indmar. Indmar said both oils ( valvoline 20w50 premium and rotella t diesel 15w40 ) will void warranty.

Ordered pennzoil from amazon today.

I think dealerships should be required to stock recommended oil.

From the owners manual.

Indmar recommends 15W-40 Pennzoil Marine in their engines. If not available, use a 15W40 motor oil with an A.P.I. classification rating of SL/SJ/CI4/CH4/CG4 or equivalent. Synthetic oils are not recommended until after the engine has been run for 100 hours.

No matter which brand oil you use, as long as it meets the class ratings you are fine.

[uniwarking]

I was surprised to find out my dealer wasn't using the recommended fluids either. 20hr service and 1 year service was part of my purchase so I didn't think much of it.

My dealer ended up using Merc full synthetic 20w40. I was a bit concerned about the incorrect weight but this oil is far superior to the Pen dyno oil IMO.

Doesn't matter at this point, what's done is done and I'm sure the oil won't be the cause of any issues I have.

You got that right. Maxpower made this point last time the oil issue came up on here. When was the last time anybody heard of engine failure on one of these from an incorrect oil? About never. The modern oils are pretty darn good and changing it on schedule is probably the most important thing you can do for longevity.

[slipperyrockTKE300]

Dealer I bought my boat from was located next to a NAPA Auto Parts, and always used NAPA brand oil in every boat he serviced.

I still use it.

[jmb]

Amazon.com has the Pennzoil 15w40 marine oil. Dont even have to go to the store

[zabooda]

The API certification on the bottle is all you need. The oils that meet the requirements including SC would be covered under warrenty with no exceptions. It would be a long day in court if the warrenty was voided for using an API certified oil that wasn't a "recommended" oil by SC. I think you would get support by the oil manufactorer if they found out someone was accusing them of manufactoring inferior oil that meets certification. It will never happen.
