Which oil filter for 450HP engine?

[agouge888]

Which oil filter are you using in the 450 engines? Also I have been using the Rotella 15w40 in the other boat...would u use the same in a 450 engine?

Thanks,

Motorcraft FL-1A is the least-expensive (and good quality) filter.

The proper PCM branded filter is here --> PCM Oil Filter

Below is the chart showing oil requirements.
Rotella 15W40 does not meet the GF-4 (or new GF-5) requirements.
Good luck finding an oil that does, and is SM rated as well. It is not easy.



In fact, based on this information from Wikipedia, I believe PCM may have made a mistake in their requirements, since according to this, GF-4 doesn't apply to the 15W-40 weight. Also, since GF-4 was eliminated in 2011, it would be impossible to find today. It has been replaced by GF-5.

I am going to visit PCM on Monday, and I will check on this with them at that time.

ILSAC


The International Lubricant Standardization and Approval Committee (ILSAC) also has standards for motor oil. Introduced in 2004, GF-4^[14] applies to SAE 0W-20, 5W-20, 0W-30, 5W-30, and 10W-30 viscosity grade oils. In general, ILSAC works with API in creating the newest gasoline oil specification, with ILSAC adding an extra requirement of fuel economy testing to their specification. For GF-4, a Sequence VIB Fuel Economy Test (ASTM D6837) is required that is not required in API service category SM.

A key new test for GF-4, which is also required for API SM, is the Sequence IIIG, which involves running a 3.8 L (232 c.i.d.), GM 3.8 L V-6 at 125 hp (93 kW), 3,600 rpm, and 150 °C (300 °F) oil temperature for 100 hours. These are much more severe conditions than any API-specified oil was designed for: cars which typically push their oil temperature consistently above 100 °C (212 °F) are most turbocharged engines, along with most engines of European or Japanese origin, particularly small capacity, high power output.

The IIIG test is about 50% more difficult^[15] than the previous IIIF test, used in GF-3 and API SL oils. Engine oils bearing the API starburst symbol since 2005 are ILSAC GF-4 compliant.^[16]

To help consumers recognize that an oil meets the ILSAC requirements, API developed a "starburst" certification mark.

A new set of specifications, GF-5,^[17] took effect in October 2010. The industry has one year to convert their oils to GF-5 and in September 2011, ILSAC will no longer offer licensing for GF-4.

Jeff,

I agree with you on the FL-1A. Good quality at a low price. I'm interested to hear what you find out about the oil from PCM. I've been using Rotella for years in my boats, but would like to find a non-PCM branded oil that I can buy locally that meets PCMs specifications.

[agouge888]

Thanks for the info Jeff,,,I was hoping it was an FL-1A...gonna change the oil tomorrow or the next day so that would be great if you could find out if Rotella 15w40 would be fine. If it isn't...maybe they could suggest something that meets the ratings.

thanks, Andy

Yep, I am interested to hear what PCM has to say about this myself. I will post as soon as I get the information from them tomorrow.

[agouge888]

Jeff, let us know what you found.

thanks again,
Andy

any updates? need to do oil change

There was a discussion of filters over on CCF. A chart was created evaluating a range of filters. You will note that the FL-1A was ranked low.

Royal Purple makes a 15W-40 that meets GF-5 specs.

[NautiqueJeff]

I saw that, but I believe their statement regarding GF-5 is in reference to all of their oils, not specifically the 15W-40. Since that spec does not apply to the 15W-40 weight (according to ILSAC itself), I don't see how this oil could possibly meet that standard.

[agouge888]

Thanks guys.....So what do you think most dealers are using for the oil changes(oil) so that they are up to standards? I need to figure out what's best to use. Jeff, did PCM have any recommendations? Let me know..

thanks,

[NautiqueJeff]

They did, but the person I wanted to ask had to leave before I got a chance to ask him. I have e-mailed him and I am waiting for his response.

[Whitetail15]

My dealer said they go with rotella T5 15w40 synthetic or royal purple 15w40 synthetic at the 20 hour service in the H6 motors. I have the royal purple and mobil one filter, think i am going with that.

Just to throw a wrench in this again, I just found this from 2016 .....PCM says that synthetics are not recommended ....I'm really corn fused now

PCM has never recommended synthetics. Not to say you can't use them, but apparently there is no advantage in boat engines which run cooler than car engines and rarely get used in extreme cold weather. They just cost more with no proven benefit.
