Bearings are cheap and easy to change. Why risk ruining your crank to save 300 bucks? I'd change them at 750k no matter what my samples read.

 

That's where the samples come in. They'll detect higher levels of wear and heavy metal contamination, signaling to get it home and in the shop and get the pan down.

I don't know...I'm fond of my Gulf Coast Bypass Filter, and 2 gallons of topoff oil for $26 bucks for Rotella 15/40 doesn't bother me in the least. Better than $300+ every 10k miles.

 

Said some people , not all. Any bypass filter that will filter down to two micron will work fine . CAT had one (may still have) a 2 micron spin on filter . Base was like 80$ . Like 20$ for the filter. Put one on Dad's truck.

 

All depends on the individuals preference and attention to detail. GCF filters down to 1 micron, and eliminates fuel and coolant contamination (so THEY claim.) I don't go on other people's hearsay, my proof was in the 1 year period that I actually had one in service on a first generation ISX 600 that was unhealthy to begin with and watched all of the higher contaminant levels actually decrease over that one year. No way would I believe that from a salesman unless I did it in real time, so that's what I go by anyways.

 

OK. You have indicated that the bypass filter technology will save you money in the long run.... I change oil at Speedco every 15 k and with all PM things (greasing truck and trailer, adding fluids, changing filters and so on) it is about 350 a visit on average, so if your annual mileage is 120k a year that's 8 visits and $2800 of total annual cost.
With that mileage and bypass filter what's your PM cost? You still must have some... need to grease truck and trailer, change fuel and air filters.
But I am more curious about the engine durability. Does it live any longer with the bypass? Assuming the constant driving habits.
I don't feel like looking this up...So let me ask... what's the cost of installing the bypass system? Has it given anybody any technical problems? After all, if it had been such a great technology, why don't the engine designers include it with their design and you have the bypass filters at the factory level? Ha Ha.

 

i run the good,5 micron wix full flow filters on mine. the XE's. i think the factory detroit diesel bypass filter from wix is 5 microns too. detroits turn the oil black fast,like immediately,so i like to use the good filters.

we also ran spinners on them all back in the 90's.

 

Engine designers do include it, or at least they did. I had a 91 series 60 with a detroit oem bypass filter. When i was speccing this 03 freightliner it was still available.

Edit to clarify: like many things they were an additional option you could spec when ordering new. So if you only buy dealer stock, you won't get one. And like many things, there are better products available than what the oem offers.

 

Answer = they only need it to last past the warranty .
