Sounds reasonable to me and reflects what the owner's manual says.
I'm in the trucking business but have been out of the maintenance end for a
few years. In the old days we were extending the oil changes on Cummins
diesels...9 liters I believe, 350 HP....from 8000 miles to 12000 miles. I
was talking with the owner of some 500 trucks last week, and they are now
extending the oil change from 30,000 miles to 60,000 miles! They have added
some in-line oil filters to each truck, but see it as a major cost saver.
They are also regularly getting over a million miles per engine with only rod
and main insert changes around 750K.
I know a lady here in El Paso that took her Ford in for an oil change at
80,000. It was the first change since new! She said, "hey, I kept adding
more when it needed it". Last time I saw her the engine had some 140,000
miles on it and was going strong.
