Speaking specifically to break in period here. Just picked up a new vehicle with a 4cy that's easy on oil. Im considering running the factory fill for 5k and replacing with M1 AP and a Fram Ultra and running 15k then moving to a 20k oci with the M1AP and fram ultra. Does this seem like enough time to let the initial contaminants work out of the new engine?
Will this oil adequately protect a DOHC timing chain system in extended drains?
FWIW i will average about 20k per year...lots of highway. Currently run Synpower to 10k and it holds up beautifully.
Please don't start in about warranty...i could care less.
