Purolator PL14610 vs Purolator ML16817

[etalors]

It seems that Purolator is recommending the ML16817 filter for the ST1300 and motorcycles in general. I switched from oem to PL14612. From Google I found the comparison below. Anyone use the ML16817 or thinks that the PL14612 is not suited for a motorcycle.

The Purolator PL14612 (PurolatorONE) and ML16817 (Purolator Motorcycle) are different filter types. The PL14612 is a passenger car/light truck filter for high-mileage engine protection, while the ML16817 is specifically designed for powersports applications (motorcycles/ATVs). They are generally not interchangeable due to different thread sizes and specifications.

Key Differences:
Purolator PL14612 (PurolatorONE): Designed for automotive applications, offering advanced engine protection and high-efficiency filtration for cars.
Purolator ML16817 (Motorcycle): Engineered for the high-pressure, high-RPM requirements of motorcycles, often featuring a heavy-duty casing and specific bypass valves.

Recommendations:
Always use the filter listed for your specific vehicle. Even if they appear similar, Purolator filters are built for specific vehicle specifications.
The PL14612 is for passenger cars (e.g., Nissan, Mazda), whereas the ML16817 fits select motorcycle/ATV applications.

I used the Purolator 14612 or 14610 for a few years, no problems. I have 3 vehicles that use the same oil filter,(PLUS I do the maintenance on my sister's bike, which uses the same filter) so would get them in quantity. I switched to Wix filters when the Purolator filters became pretty pricey, and harder to find in my town. I order them from Rock Auto.

Is the ML16817 way more expensive than the 14612?
Just curious.
I've used Purolator 14610 (longer than the 14612) for hundreds of thousands of miles with no issues on all of my ST1100s.

A quick search found Walmart's pricing for both - ML = $37.13/3 and PL = $25.22/3. Both prices were for 3 filters
Menards has been my go to for filters. the PL is $7.11 each but you have to do their $^%#&-ing rebate program. They are always holding some of your money. The out the door price is $7.99....with 88¢ rebate available on the next purchase.

Thanks - I just can't imagine why the ML would be almost $4 more.
What would really be interesting is to cut each one apart and see what the real differences are besides price.

Perhaps because it is labelled specifically for motorcycles? Not unlike most other commodities labeled similaryly like "motorcycle" oil. Change the colour and packaging and voila.....same filter for more money.
Never pass up a chance to capture more margin!
Literally millions of miles on ST's using the Pl14612/14610 so I doubt there is enough of a difference to justify the "motorcycle" specific filter.

What nobody has talked about, are just because the filter housing, media, and threaded fitting may be the same, or similar, did anyone stop to think that maybe the back pressure relief spring may be different between a motorcycle and a truck?
You should always check the pressure of the bypass etc.
A care or truck could be significantly heavier than what is required for a motorcycle engine.
Check the specs.

But won't your hair catch on fire and your motorcycle engine explode if you don't use a 'proper' motorcycle filter?

AFAIK, CalSci did that so that is why I have used the Purlators all these years.
They seem to be a very reputable outfit.

As long as you use mobil1 4 T 10/40 oil it's all good....lol .....

Is it better to have the valve open too soon or too late if the filter becomes clogged? If you change filters with every oil change (and why wouldn't your?), use the correct weight of oil, and the filter gets clogged, you have more issues than the wrong bypass valve pressure.

Years ago there was a long running discussion and hunt for the specs for the relief valve on Moto Guzzi oil filters. In the mid to late 70's, some models hid the filter inside the oil pan. By and by, the Outsider was made, a frame that fit between the crankcase and the oil pan that had piping and channels and a nipple outside the pan upon which screwed the oil filter. A fly in the ointment was nobody could find published specs for name brand filters or the MG filter. You replaced the OEM item at your risk. AFAIK, nobody blew up a bike by using an unapproved filter.

Thanks Andrew, as I suspected, the BPV is much lighter for the motorcycle.
Most folks will never know if the have a failure until the filter fails, and the BPV does not open etc.

 

[Larry Fine]

The bypass "valve" may open some during high-RPM operation, too.

Honda has several part numbers for the ST oil filter (15410-MFJ-D02, 15410-MFJ-D01, 15410-MCJ-003).
Honda does not appear to publish the bypass relief pressure valve settings but from what I can find, they are in the 12-17 lb range.
You have to wonder, in this day and age of lawyers, if any company would spec a filter that would put it at risk of a lawsuit.

I keep waiting to hear of the first oil filter related failure of a ST engine. Maybe my 5 year old grandson will be the first.

On the ST1100s, it's usually the water pump or tensioner/pulleys that take them out ...

 

[Al st1100]

let's have a poll, how many ST's have oil related engine problems.

remember, anything marked boat, rv, atv or motorcycle always cost much more. Oh almost forgot...snap-on too.
