I know we're getting a little off the original, but to answer the first post, I used to have an oil consumption problem (1-1.5 qts/3000 miles) until I switched to the Castrol extended life dino juice. Now I'm down to about .5 to .75 per 3000 miles. I'm convinced it made a difference in my trucklet; anyone else have the same/different results? In addition, what's the concensus on 10-40 in an engine with 140,000 miles on the original engine? Average use is 85 miles per day commuting, mostly at highway speeds (55-65 MPH) and a warmer climate (SC).
Thanks, Bubbazuki
