forgive me if this has been covered before ...
i saw a duramax owner top up with a PCMO 10w30, and i cringed just a little.
now ... i', of the opinion that it is better to top off with something, rather than run it low, but we were only about 5 miles away from a truck stop that carries HDEO's.
just looking for opinions, i guess. what's worse? using a PCMO in a pinch, or running it low until you can get the right stuff?
