I thought you were happy with the Rotella 15w40. Me too so far.I guess the main thing is to keep the oil/oil filter changed every 5000 miles. With my truck I do the 6 month or 5000 which ever comes first, usually the 6 month period comes before the 5000 mile mark. I would say on average I have around 4000 miles in a 6 month period. Am I doing this right with the 6 month thing or just wait to get the 5000 mile mark each time?
Thanks

I do *LIKE* the 15/40 rotella...get it at costco (they just downsized
the case from 6gallons to 4gallons though) ! Last time i bought it
it was about 55 bucks for a 6gal case (so i bought 2 cases)
personally if my truck was sitting that much, I'd be doing some
oil sampling...before i changed it @ the 6mo mark...you might be
able to go more than 6mo (if you dont have the 5k miles on it)

fwiw i ran the dino 15/40 rotella in the winters when we lived in virginia...never had
any problems.
