I'm at 133K on the odo, and after nearly 60K miles free of oil consumption (since GM replaced the pistons & rings), the engine's starting to sip some again. It's only about 1/4 qt. in 2K miles, but I'm wondering if there's any worth in trying the oils that are ostensibly formulated for geriatric motors.

Have any of you run some through your crankcases? Did you notice any difference? If so, was it positive?

Thanks,

FC
