2014 silverado 5.3

[aimatdeer]

Hello everyone i have a 2014 chevy silverado with the new 5.3 ecotech engine.i am thinking about once my free oil changes are done switching to mobil1. Does anyone have a 14 or 15 and are currently using mobil1?
If so how do you like or dislike it.

Just use anything Dexos approved. We run a fleet of 5.3's and 6.0 powered trucks and they all run great on whatever approved synth/semi-syn is on sale...

Your 5.3 is the latest GEN 5 version with Direct Injection. This engine calls for 0w20 and I would recommend a good synthetic in that grade such as Mobil 1, Pennzoil Platinum, etc.

Would the correct filter for the 2014 be the longer PF63?

I don't own the truck describe above, but from what I know. Like what other say, use what other say, use a dexos1 approved oil. Since your truck calls for 0w20, then your only choose so far, other than AC Delco oil is a full synthetic oil. As far as Mobil 1 goes, regular Mobil 1 does not have a 0w20. You would either need to use Mobil 1 Advance Fuel Economy or Mobil 1 Extended Performance.

I will stay with 0w20. The gm fill is synthetic blend. I want to go with the advanced fuel economy and it is dexos aproved.

Yes it is a PF63.

Any Dexos rated 0w-20 is great. Personally I grab two 5 quart jugs of M1 or PP and a PF63 filter at Walmart for about $65 out the door. Most of the Ecotec 5.3 UOAs show no issues with fuel dilution so I go for the full length of the OLM which works out to about 7200~7500.

Based on the PQIA analysis, you might want to take a serious look at the Quaker State Ultimate Durability 0w20 for your 5.3. It is on the dexos approved list if that matters to you.

How many quarts does that 5.3 Ecotech hold?

 

[splinter]

Mine hasn't blown up yet. Good luck.

Thank you! Glad to know now. You'd think GM would mail that out to owners or something. I never visit the dealership.

Don't feel bad, they updated the service manual on capacity and didn't tell us techs that work on them either.
