For our Schaefer rep only please---For my new 06 Chevy 3500 pickup with the LBZ version of the Duramax--Just did my first oil change at 1K with the 200X dino oil with the moly--good choice? Ideas on mileage changeouts,sampling,etc. Thanks,Wayne
yes, great choice. This is the 100% petro base. The 15-40 semi-syn or the 5-40 straight syn would be a step up for future changes.
