post #10 specifically?..yes… you are right.
the rest is realevent to ALL engines.
go with factory for the first spec’d change
then go with better than regular service intervals…dont forget manufacturers considder anything similar to what we considder normal driving, as Extreme.
for has denied warrantee to some people for not being able to prove 3000k oil changes on high mileage/year vehicles.
why because some service mgr’s are A** holes and think they’ll get a gold star for this.

I have personally seen this while working for ford in 2000 and 1999.
