I just returned today from our Florida trip today with 11K now on the oil. Zero oil consumption this entire OCI as always. I plan to change it if I can find M1 5-20EP. I only checked at one WM this afternoon and they are nearly out of M1 oils. Clerk in the auto department says there was a fire at XM someplace causing the shortage. She claims as soon as they get a shipment in it's gone.
