Trailblazer SS Oil Question

[LS2PWRD]

Hello guys, first post here. Recently bought an 07 Chevy Trailblazer SS AWD. I have been reading around on here for a few months and have been debating between Mobil 1 0w-40 and amsoil 5w-30 XL. I can get the amsoil for the same cost locally as the Mobil 1.

The TBSS’s LS2 is cammed, with upgraded oil pick up tube, lifters, melling pump, etc and getting a fresh rebuild. After the engine break in what oil would be better to use, if any? It will be paired with a AC Delco PF63 filter as well. I live in Northern Michigan and daily it so it does see very cold temps, around 0-10 usually, during the winter months.

For the winter, 0W30 Mobil-1.
Never been a fan of AC Delco filters - not since the shift to new suppliers a decade ago. I own GM products.
Run a basic EG, Tough Guard or Wix.

Amsoil or Royal Purple HPS over Mobil1 any day all day.

Mobil 1 0w40 year round! Case closed!

Sounds like a very kool ride! Congrats!

Mobil 1 5w30 year round.

For the same price i would have the amsoil. 5w30 is plenty thick if you wont be racing every day. 10w30 is a option but not in your weather it sounds like. I run pennzoil ultra platinum 10w30 in my lm7.

Welcome and congrats on the new to you purchase..

Nothing wrong with Ac Delco filters they are a good choice - I use them myself even on non GM vehicle never had an issue.

Stick with a quality full synthetic like Mobil 1 or Valvoline Advanced for example - Your safe to run 5w-30 year-round.

Mobil 1 5w30 is all you need

Northern Michigan as in north part of down state or the UP? For everyone else, they are literally two different worlds climate and culture wise.

If the UP, M1 0W-40 would be a good choice for the whole year. If lower MI then any decent synthetic 5W-30 would work year round, buy based on price.

Now if you're in Keewenaw County, that's a whole 'nother story!

Beef up the tranny if it hasn't been done so already. Blew my '07 with only 12K on the odometer.

Seems to be a common occurrence.

Thanks guys. Only reason why I really didn’t want to run the amsoil was due to not being able to buy it somewhere quickly if I’m in a pickle and need some quick, such as Walmart or something. I think I might switch it up as the Mobil 1 is now available for $32 for 7 quarts vs $49 for 7 quarts of amsoil.

Live in the UP. Right on the border of Canada actually. Can see Canada out of my front door. I’m thinking the Mobil 1 might be a good option. Unless I can get 0w-40 amsoil, would that be a good option?
