I just bought a 2006 silverado crew cab LT and I am wondering the average engine life for the 5.3l?

Consider 250K a very easy number to hit if you take proper care of it. It isnt anything to see these trucks on the road with 200K plus miles.

X2 what murdog94 said. Taken care of they seem to last forever.

my dad told me once.what ever you have treat it like its ready to break.if you do that from day one before you know it twenty years have gone by and people will be admireing you truck more than when it was new.

X2, maintenance is the key & what you subject this truck to will determine the life it has & the miles you'll get out of it. There are many members here who have seen 250K to 350K on their trucks with normal maintenance.
