Winterization of an LT1 - Checklist
 
2 Attachment(s)
Well.. first time winterization of an LT1. I have read tons of posts and modified Eastie's (JimN?) checklist and supply list to be specific to the LT1. I have chosen to drain the block, fill with antifreeze and dry block again as it seems a bit more fool proof for noobies and meets all concerns. I have also re-orderd the checklist a bit so you can go right down the list in order. So... have a look and let me know what you think.

I would recommend VR1 Synthetic 20w50 or Royal Purple HPS 20w50. 1996 I believe still a flat tappet engine.

I had a hard time just finding 20W50. Only brand I could find was valvoline. I was hoping for a choice or two. Maybe Mobil1. This was just this past spring. Maybe this fall I will find a better selection.

i would run good 10w30 on an LT1 the bearing clearances do not warrant 50W oil

Everything that I can find say 20w50.

Oil was about the last thing I figured we would be talking about after posting the winterization list... I guess you guys think the tasks, order, etc are ok?

I don't use antifreeze on mine. Was told its bad for the alum heads. Assuming you are using rv stuff, not real antifreeze which would be un tree huggerish.
Also i think I've been using 15/40 for a while now.

X2 on the antifreeze. I've heard the plumbing antifreeze is hard on the aluminum heads. I leave my LT-1 dry.
