Hopefully someone can enlighten me, I feel a bit confused about this matter... I have some people telling me using aftermarket oil filters provided at PM service places (TA, Loves, etc) is completely fine. I have some other people telling me that I should buy OEM oil filters on my own and have them use that instead of their own...
Just wanted to see what actual semi truck mechanics/professionals thought on this issue. This would be for a 2023 Freightliner Cascadia with a DD15 and about 90k miles on it. Also, would your answer also apply to the other filters? (fuel, air, fuel/water separator). The truck is mainly used for long haul OTR, mostly highway travel
Forgive my ignorance, and thanks in advance for any guidance.
Question regarding OEM vs Aftermarket Oil Filter
Page 1 of 2
Aftermarket filters won't void any warranty. There are numerous stories from shop owners who will tell you, and I have seen it firsthand, how aftermarket parts caused problems, including filters. They won't cause problems 100% of the time but the honest ones who care about quality (and not comebacks due to parts) will tell you to use OEM. Too many times I tried to go cheap and/or aftermarket I got burned. Some learn the hard way. There are limited exceptions where one can determine who the OEM manufacturer is and buy the part from them. It just won't say Freightliner or DD or Toyota on the box but the part is identical.
I would highly advise using OEM filters at least until your engine warranty is up. I have seen aftermarket and incorrectly installed filters cause serious engine wear/ damage not covered by warranty.
Air filters and oil filters are the biggest offenders. Occasionally fuel filters if the incorrect part is used for the application.
It's all a write off, so there's that. IMO, there isn't a difference in good quality filters. I'm talking Baldwin, Fleetguard, Donaldson, or OEM. Those listed above make OEM filters. Any others, IDK.
I think he is talking "fleetguard" vs "baldwin" or something like that.
I got an isx and I'd prefer fleetgaurd. During the crunch of the parts shortage, I could care less and had no anxiety of running balwin
My view is oems design an engine to X spec. Thus the parts they use need to meet thst spec within tight tolerances as many other parts could perform diffrently then designed otherwise. As such many OEMs will axe a company that screws with quality for the simple fact they pay well and dont want the backlash or warranty claims.
Aftermarket filters have few/no oem oversights and there can be HUGE variances in design, quality, flow rates, pressure number of holes and so on. Not to mention the companys they use may decide to cheap out on any number of parts. I think it was K&N for example (feel free to correct me) had a spat where the guys they used were selling K&N branded empty cans and destroying engines.
Dont get me wrong, a crap filter is better then no filter if for example we have another parts shortage where its crap or nothing at all. But barring that edge case. Is gambleing with a 20k+ rebuild or worse an entire engine really worth the $50 you saved? Especially if you lose?
Oh p.s also if you have your own filters then if something happens you have spares. I know there have been a few times i was sure glad to have then when my fuel gelled or in one memorable case a rock punched a hole clean through the one on my ram. Plus if they are out you have them with you already. Also heard horror storys where a shop reused filters when they ran out just to sell an oil change.blairandgretchen Thanks this.
I keep oil filters too. I've only been out here 10 years and both have been necessary.
Keep an extra belt too, or at least the old one.
Don't get me started on coolant hoses.
All this stuff is super important. When you need it.
