I’m about to store my truck for a year or so. It is almost at the end of its OCI. Should I change it now or after I take it out of storage? It is a fairly severe oil burner, if it matters.
It’s a known problem with this truck and I do a lot of short trips (cloud of smoke on startup) but you may be right. The previous owner used a mediocre synthetic blend oil that probably dirtied it up over time.
