I agree that the two glue beads should not cause that much are restriction flow. The mopar filter I took out was really very dirty. But with the Wix, started having problems. Now they are seemingly fixed as soon as I put on a mopar again. I can’t explain it and it’s also my own anecdotal experience. So who really knows.
Mine is regenerating every 10-14 hours with combined city and highway (interstate)driving with 6200 miles (half of those towing a 7K travel trailer)and the original 5031ab filter. Sometimes the DPF gauge will go half way up to the 12.5% mark for a bit then go up to the 25% mark. Then a little highway running and it will drop back to halfway to the 12.5% from the bottom. It does this a couple of times and then when it hits 25% and goes into regen. IDK and I’m afraid the dealer isn’t going to know either. But it hasn’t thrown a CEL for the p2459 excessive regen frequency yet.
That’s as good of a theory as any others I’ve heard.
You have to be on the DPF gauge on the EVIC screen.
The WIX I had on the shelf has no glue strips. The glue strips were obviously a cost saving measure compared to forming the filter material to keep the pleats separated. Also the foam frame on my WIX is orange. Bought it a couple of years ago. I was stuck with a couple of AAs so put in the WIX.
Thanks Jay. It would probably just get me into trouble.
Higher RPM=Lower EGT typically, while lugging the engine isn’t good it will heat up the after treatment system better than what your SA told you.
Yeah, I have found this too. Towing at 65mph in 6th gear and rpm's are at about 1,500. Lock out 6th and it runs at 1,900 or so but with EGT temps much lower all the way around. Like 200+ degrees lower. So torn as to what is best. The truck runs all day with no complaints in 5th and with no noticible difference in MPGs. But having the EGTs a couple hundred degrees higher in 6th over all of a 4 or 5 hour drive seems good too????
Sorry, what is EGT. I thought a higher RPM would raise temps. What are you referring to after treatment system? While regen is in process I understand you must be traveling over 55 mph. At that speed it's only pushing 1500 RPMs. Thanks for your input.
EGT=exhaust gas temperature
Higher RPM moves exhaust through the entire system (intake through exhaust tailpipe) faster, creating a cooling effect. Low rpm operation under load causes heat to be retained in the system. Back in my modified 12 valve cummins days I’d drop a gear on hills to cool things down, pulling a load up inclines for a extended period would come close to burying the egt gage. Drop a gear, instant cool down of a couple hundred degrees.
