Hey folks, been a while
Search has turned up nothing related to my question so I'll post it.
Last June I moved from one town to another, and started driving way more highway mileage than I had previously.
Last fall sometime I was getting a code that I traced very quickly to my CPAS having eating its screen. I was able to pull out most of the screen bits that had gotten jammed in the actuator body and ran it a couple days with no code. Then I replaced it with a brand new part (obtained at local dealer for a surprisingly competitive price).
The above may or may not be related to the issue but seems like the only thing that has a remote chance of offering some explanation, but since that point in time I've noticed that my OLM permits what I'm starting to think are excessively long oil change intervals....that last 2 have been in the vicinity of 18,000+ km (~11,000+ miles).
Anybody care to share their example of long OCI's for comparison? Anybody else ever hear of the OLM permitting excessively long OCIs?
I'm kind of wondering if it's possible that some small part of the disintegrated CPAS screen worked it's way in and jammed in some narrow channel and is perhaps restricting oil flow to/from some area and thereby altering some data point on which the OLM / OCI is based. Or is it just the sudden jump to vastly more highway miles driven that's allowing longer intervals than I've experienced in the past?
Anybody know the exact algorithm / process for the OLM to arrive at it's indicated value?
Ok, I'll leave it there for now. Thanks all in advance.
EDIT 1: I've been running full synthetic always since I first bought the truck some 180k+km /6 yrs ago
EDIT 2 : @Sparky seems to suggest in this post that 10-12k mile OCI's are common...so for the moment I'm taking that as a good sign and assuming I was only getting 10-12k KM due to the higher demands of primarily city start/stop driving
