what oil Brand do you use on your Rig?

[mattluttrell]

I use the cheapest oil. I believe staying on top of the oil changes (especially in axles, transmissions and transfer cases) is more important than brand. I'll even run cheap Valvoline or AutoZone brand in the BMW which "requires" expensive synthetic.

I've never had anything fail or have any damage. I've seen others have failures due to neglect; not the label on their oil.

may not have failed yet but oils that don't meet the classifications that the engine requires will suffer over time as well as cheap oils don't always have goods additives added like detergents. using oil that does not comply is neglect.

I have a 2011 Yukon Denali with the 6.2 in it. I purchased 5/30 amsoil to put in it but realized that amsoil is not Dexos approved. I have done research and read that amsoil exceeds Dexos 1 and amsoil claims it is jus a licensing thing and they do not chose to put the Dexos approved logo on there jugs. Jus wondering if something ever did happen with the motor and was a oil issue would Gm warranty it if amsoil does not have the approved label. Does anyone run Amsoil, I see a lot of people are running Mobil.

Mobil 1 synthetic 10w/30 changed every 12000 miles

I tested it

^same engine oil changed every 5-6k not sure on gear oil.

Why do you change it so often, it can run for 15K without breaking down that's the plus about Mobil 1 5W-30. I test oil for a Cargill Facility and I decided to check the viscosity and the break down wear of my Oil at 10K miles using the CSI 1500 oil analyzer and there was no change in the oil which means you could put the 10K oil back in the bottle and sell for new. For the price of it you could save a lot of money running that extra 6K miles

 

[SunlitComet]

No change at all. Sorry I need documentation before I would believe that. As for the early changers some people are just misinformed about improvements in chemical advancements, engine system improvements or have a mindset that they will not break.

Absolutely no way I'd run 15k miles between oil changes lol

I used Valvoline Max Life Synthetic blend 10w-30 on my 98 and my 07

Anyone know how accurate the "Oil Life percentage" in the gmt900's is, I run RP and change it every 10k (6200 miles). Just curious if anyone goes by that.

Allot of people running valvokine now it seems.
