Mopar oil filter

[Topzide]

I'm running a bypass setup on my 2014. I had the setup prior to the truck landing in my lap! Was going to play with the 2001 gasser. I know it doesn't make that big a difference on mine, but had and put on. Made oil changes a bit easier since I relocated full flow/ bypass under passenger floorboard. It's an Amzoil setup were they're side by side. This fall will be the 2 yr mark for the bypass. Will open up to see what's been caught! May just end up running 2 LF16035's, 1 full flow and the other as bypass. Just like to have the extra filtration! Main thing is good oil and filter change as needed per driving conditions.

Bypass oil filters are extremely good at what they do - but even running the cheapest over-the-counter full flow filter, this Cummins diesel will outlive me - and bypass filters to vast majority of owners of these trucks is usually a waste of time and effort. They have provided me with all the efficiency and benefits promised by the maker - and provide a "warm and fuzzy" feeling related to over-the-top care of a vehicle I've owned for 20 years - but not many here are likely to do that. For them, my personal advice is, buy the best lube and filters you can afford - pay attention to service intervals - and enjoy that high-priced piece of hardware, and you'll quite likely be rewarded with long and reliable service.

$70K-$90K for a truck? No Way, No How - and for sure, I'd want to take VERY good care of a vehicle that cost more than the first 4 houses, combined, that we've bought thru the years - and yeah, "inflated $$$", but still WAY more than *I* EVER intend to pay...

Kind of a waste of a LF16035. The point of a bypass system is one filter has a very small micron rating, like 2, and over time all the oil "bypasses" the full flow and goes through the bypass filter. If I had known 18 years ago that I would have these many miles I would have installed one.

AMEN!
IF, I was a big rig owner/driver, for sure, I'd want to get as many miles as possible out of my long haul bread and butter machine.
My dad drove his own cattle truck, and used a bypass filter on his '55 chevy cabover truck for over 1 million miles, on 2 chevy 327 small block engines. a few years after he retired that truck, I took one of those engines, overhauled it, and with a Duntov cam and 4 barrel carb, swapped it into a '51 chevy pickup - and used that SAME bypass filter off his old truck - I've used that same bypass filter on my '91 Dodge/Cummins - and now it is on my '02.

Yeah - I'm sold...

Sorry, but you’re really not following the fact that there are different types of media and they are not created equal, nor that you can’t fully judge a filter by looking at it.

You bet I’d run a single wrap if the media warranted it, but that’s because I know there are different medias and understand that they work differently.

you can judge whether or not the filter media is spaced evenly meaning it has an equal amount of filtering media the entire surface of the filter

The most miles I ever ran on an oil change is 15000 with an oil sample done by cat every time never ever once one had a high containment count dirt or fuel or antifreeze or wear metals . I ran either fleetgard or wix filters and only the factory oil filter . I could have easily ran 30,000 miles probably 60,000 miles with the factory filter setup and full synthetic oil . I use my trucks for commercial type hauling and I make sure they are maintained right .

JUST for the benefit of those not familiar with oil analysis - here's a sample of oil from my '02 at 20K on the oil, and the use of a bypass filter - I was having my oil analysis done by Blackstone Labs:

It's funny how a lot of people across many forums still deny the feasibility of extending oil changes even with oil analysis proving it to be safe when using a proper bypass filter/setup. I use the lf9028 fleetguard filter. Lots of information out on it but there is a huge difference in oil color alone.

The Donaldson DBL7349 has better overall specs and is actually rated for the application, not to mention the major price advantage to the Donaldson.

A bypass isn’t the main factor in extended oil change intervals, but oil quality and duty cycle are major factors. Filtration is key, but a bypass won’t effect TBN which is often the determining factor in oil life.

None of the high horsepower ISB’s get the LF9028, which should be a good indicator it’s not for us. Older stock 5.9’s are probably ok on it, but not once modified.

Bypass filters have minimal impact on oil color with modern oils. The additives that keep the oil from soot thickening also keep soot from being able to be filtered out. Short of a centrifuge the color just won’t change much. The best bypass filters run 2um and soot is sub micron.

On gas engines there is a noticeable color change with a bypass, just not so much with modern diesels anymore… even ones without emissions stuff. It’s the oils fault, not the filters. The oil is still much cleaner with a bypass than without.

AMZ/OIL - Donaldson filter used here with AMZ/OIL 15-40 Signature series. 22k and they said to try 24k next time!

Kinda proves as AH64ID mentions quality filtration and oil is the key.

I’ve ran 15000 milt oil change intervals and never had an even remotely high number on anything on regular oil samples never ran anything more exotic then the fleetgard microglass filter
