Mobil 1 far exceeds the dex spec. That’s why it’s dex certified.

Good grief. Have you not read any of this thread?

Very carefully do the math —- 30% longer intervals. 45% greater cost.

GM requires a full synthetic spec oil in most HO LS and all dry sump. Thats what I meant.

Holy shit you’re going through a lot of effort to contest a point I’m not even trying to make. I’ve been in a franchisee dealership service department since the mid 80’s and I’m taking a few liberties with my descriptions here

Ok.

It’s a bit of a higher standard. It weeds out all the garbage oil out there.

Mobil 1 meets Dexos requirements. As just about any full synthetic does.

Holy christ.

I understand what Dexos is.

I understand that.

Oh I’m sure most full synthetics meet Dexos requirements.

I agree with what you are saying.

What oil change jockey opens the manual before he squirts oil into your motor?

Dude. Have you read any of this thread?

Correct.

Not according to GM bulletins. Any dry sump requires Mobil 1.

I’m sure this is all true.
