That’s a good filter. Just curious, any reason for the switch from 5w30 to 5w40?

I think I’ll take a lubrication engineer’s advice who worked for NASCAR who repeatedly shows the data behind his claims over advice from a faceless dude on the internet, but thanks.

The test from that machine literally is the proof. Not sure how that was missed. 🤷🏻‍♂️ Wear went up 3x using a diesel oil.

What oil did your company use for their GM trucks if you don’t mind me asking?

I wouldn’t use a diesel oil in a gas engine. There’s plenty of good 40wt gas engine oils to go with. Mobile has the dexos R stuff that GM recommends now for the 6.2 but it’s about $16 a quart. There’s plenty of euro oils that cost less and should work just fine.

Nothing, except for that extra $$$ payment to GM for their dexos money making scheme.

In my opinion nobody should be putting mileage claims on oil. There’s too many variables to determine how many miles you can go on any oil.

What’s your oil pressure like? I run 5w30 in mine and it’s just a smidge higher than 0w20. Curious what it shows with 0w40.

Yes. The truck is 6 years old. Warranty expired sometime in August 2024.

I would too, except the warranty has expired.

Who is this “We” chick you keep referring to?

Yeah I’ve seen plenty of videos of guys doing just that on Fords and GMs. Looks to be the most fool proof way to make sure it’s on right.

If it was loose, wouldn’t that cause a driveline vibration of some sort?

I was leaning towards just doing this. What strength of loctite or thread sealer did you use?

The pinion nut is not reusable. Not sure about the flange bolts. According to GM the pinion nut has to be replaced. Otherwise I was going to do just that. Maybe I can count the threads.
