Mercruiser Oil Filter Comparison

[Grease is the word]

Schmoe,

The PF35 isn't made anymore and the PF1218 takes its place.

The PF1218 is longer than the PF35 and has ADBV. AC doesn't make the same length as the 35 anymore. You have to go longer (PF1218) or shorter (PF454 which also has ADBV).

Grease: Hey, glad we can motivate ya! I usually depend on beer for that.

Dan: The most striking (and frightening) thing about your two filter photos is that those monsters must be 5 ft tall! I assume you use them to barricade the doors to keep out the beer-seeking, toothless, trailer trash women.

You had mentioned the microglass/StrataPore media a while back, and I recently came across this website which has some interesting details on that media. For example, I thought it was a glass product (fiberglass), but it's "melt blown molten polymers," which I believe is the same stuff Captain Crunch is made of.

How important is this when using in GM engines that have the ADBV in the engine?

Once again, THANKS. I am going to pick up a Baldwin this weekend and compare it to my Hastings to see the differences in my application.

I kind of feel like the guy who has used Fram for 20 years only to find out their worthless. I have been using nothing but Hastings since the late 70's, on the advice of many car nuts. Know I've got the feeling "what have I done"!!! j/k...

Actually hastings used to make a great oil filter. They had a cotton depth filter that I used for years when mobil 1 first came out. Oil was filtered thru about an inch of compressed fiber.

I wish filter manufacturers still made this type filter. It filtered incredibly well and worked great with synthetic oil.

I used them till they were taken off the market.

Ross, I believe it's the by-pass that is in the engine.

Ross, I know, I have brain flatulance all the time. Let us know if you find your Baldwin.

Merc implies or says (I can not remember) that their filters have heavier shells and mo paint to fight corrosion (I have friends whose filters have rusted on their boats with predictable results.

Purolaters have very thin shells i would not use it on my merc 4 cyl -

Any evidence of that?

 

[Grease is the word]

I will attempt to put calipers on the shells of all the filters and add them to the report. For sure, the K&N had a thicker shell than all of them. I don't remember the Merc being any heavier than the others.

People use Fram PH6606 and Pennzoil Z3's (Frams) all the time in boats and I don't hear that they rust anymore than Mercs.

I will scrape the paint on the Merc and compare it to the others.

IMO if your filter is rusting, you have more serious bilge or storage problems. I have only heard of filters rusting when people leave filters on for multiple years. All I/O's expect at least yearly oil changes. My boat engine (and filter) stays pretty dry -- especially compared to a car going through rain and snow.

In a boat you are always opening the engine compartment to keep an eye on things. I never go out w/o opening it for some reason or another.

Great.

are the filter sq area sizes swapped for the wix??
That is longer filter has smaller area??

 

[Grease is the word]

Also, a BITOG member has stepped forward and volunteered to do analysis on the filter media. I will post when we are done with that information. I am very excited get this info.

This site is awesome.

Stay tuned.

Edward,

I went back and tried to see what you are refering to. I see the mistake. In the spreadsheet I have the can height swapped for the two WIX's. I will correct it.

Thanks!

The Purolators in the mini-mopar study several years back had shells 0.011" thick, while a new post (by GSV, I believe..?) shows 0.019", just a tad less than the Mobil 1's and K&N's. It would appear that Purolator has strengthened their shells in recent years.
