PPIRAX vs DELVAC

[timenright]

I have a new truck coming in and need to decide what fluids to run in the transmission and rear-end. The following are from the manufacturer’s approved oils list.

I am leaning towards the Shell products. Can anyone tell me why I should consider the Mobil products instead?

Transmission

1. Shell SPIRAX GSX SAE 50
2. Mobil Delvac Synthetic Transmission Fluid 50

Rear End

1. Shell SPIRAX ASX R 75W-90
2. Mobil Delvac Synthetic Gear Oil 75W-90

Thank you …

If you look up in the left hand corner of this page it says Use Mobil 1

Basically it means you should use Mobil Products.

Seriously, I would just read the MSDS Sheets for the trans and Diff fluids you have mentioned above, and then make a choice.
