Oil consumption

[Gross707]

With only the occasional whiff of smoke on startup my ‘84 K-10 seems to be consuming about one quart of oil every 500 miles. There are no leaks and no suspicious engine noises, so I was wondering if this is “normal.” The engine has 130k mi. on it and has never been apart.
Thanks

Still have your cat ? If so, it may be hiding the consumption. Goldie does not, so I see it - when it is warming up mainly, and at slow speeds. Normal = No.

Given the vintage of the motor, and the improvement in oil tech over the years and the horrible factory recommendations for maintenance , such as changing the oil filter every other change , it's conceivable.


On the plus side, oil is cheap !!
