I also practice all (but the OBDII) mitigation steps you documented. I have a Torque OBDII and app so will use it to monitor temp's as well. Good idea. Thanks.Dunno about all the pre oil lube stuff.. My rig only sits for a couple of days at the most without running, (daily driver). When I change the oil, I fill the new, dry oil filter with oil. After a few minutes, it does not drip any oil while installing it on the engine. I do notice that the OP gauge does not move for a second or two on it's first start after that oil change. On cold starts, even after sitting a couple of days, the OP gauge moves as soon as it fires.. Don't know what that few seconds does, but so far so good just firing it up.. At least the filter was not dry when first fired! That's my only comfort at this point I guess..
On those long grade pulls and then stopping... I have those situations going east over the pass on I-90 on a couple of rest stops. What I do is coast into the parking area and then when I stop, let the engine idle for a couple of minutes... I have a phone app that monitors the ODBII sensors and I monitor the CAT temps and once they get into the 900* range, that's when I'll shut it down.
Dunno if that makes any difference at all either, but I also wait for the fans to shut off and see the engine and trans temp lower during that time, so can't hurt, right?
My primary purpose of the Pre Luber is to address the dry starts after sitting up to 8 months at a time. The post lube benefit is a secondar benefit. I plan on using a simple twist to turn 3 minute timer to continue the post lubrication/cooling for turbo cool down. Would allow me to stop at the rest stop, run the engine until the fans turn off, and then twist on up to 3 minutes of turbo cool down while I step inside for business. Good post. Thank you!
