Redline everywhere at 1002 miles new truck

[Super Chevy]

Well...I took the plunge! Put Redline oil everywhere in my 2003 2500HD. I just clicked 1002 miles on the odometer. I will be sending the engine and trans fluid for regular checks and keep everyone posted on results. 5w-30 engine D4-ATF Allison 75w-90 Diff's I'm using wix filters and will be using redline grease for suspention components. I use my truck only on weekends for the most part(pull race cars to the track) so miles will come rather slow. 2003 Silverado 2500HD Ext.

aboard! You will learn a ton on here! By the way does your 8.1 vortec have any piston slap/engine knock at all? My 2002 LS1 just got rebuilt because of it and my 2003 5.3 has a little for about 15 seconds at start up.

Chris, No piston slap here ...8.1 is silent. Hope it is not a problem for this engine. Seems to be more of a new generation small block problem. My cousin bought a 2003 1500HD with the 6.0L I will have to listen for the problem on his truck and report back my observations on another post. Patman and Chris...Thanks for the WELCOME makes ya feel more comfortable using the forum!
