Change it before, during, or after the trip?

[Tucson Five-O]

Follow the OLM!

This isn't rocket science. I plan on leaving Chevron Supreme in my 2008 Impala until the OLM reaches 0% which will be 9-10K, admittedly in milder conditions.

Trust the OLM. If you want more TBN retention near the end of the OCI interval then switch to a good synthetic like Mobil 1, PP or Valvoline Synpower. And give us more information to help you, i.e., I'm at XX% on my OLM and it drops X%/1000 miles, etc. And try reducing the amount of cold idle time. Start the car, let things stabilize for a few seconds, then drive. I've lived in the cold country too and se Ct. isn't Iowa or Minnesota or NH for that matter!

Take care,
Gary

The '06 Chevy hangs on the high when starting at temps below 32°F and the OLM clicks off %'s pretty fast while on high idle. Given these conditions: do I change the oil before, during, or after the trip?



Many years ago I would have changed the oil before the trip. Now I'd enjoy the trip and change the oil when I got back. Just check it before you leave, top it up if need be, and have a safe trip.

After.
