Home Forums Gear Hunting Trucks and Four-Wheel Drives 2003 Chevy 2500 Duramax w/ auto: Any good???

I ran Delvac 1 to 10k in my Cummins diesel powered dodge, but only 7500 in my LBZ Duramax, which had a egr valve.

Cool. I run Delvac 1 in mine but I settled on 9,000 mile intervals based on my UOA results attained over the last 200,000 miles. I use either ACD or Baldwin oil filters in conjunction with an Oilguard bypass oil filter.

I own a 2003 chev Duramax, have replaced injectors (warranty), power window motors both doors, 3 front wheel hub assemblies, brakes, pitman and the black box? On the side of the tranny!

The worst thing about my truck is what they call 'frame beaming' between 60-80kph it bounces like your driving on washboard! GM swears its normal...they will never sell me another truck. When I bought it new it rode like a caddy at all speeds about a year in it started bouncing....if the one you looking at has any wobble don't assume it's a tire out of balance!!

BTW-just hit 255k
