Yellow cap Mobil 1

[YOOPYJ]

Wal-Mart has Mobil 1 with a yellow cap, 5w-40.
It's suppose to be a suv/diesel oil.
Wouldn't this be better for motorcycles...like a 1985 Goldwing?

I have not used the new 5W40 M1. But it should do very well as long as it is not heavily friction modified. Shell Rotella T 5W40 seems to work very well and it's $12.88 a gallon at Auto Zone and Wal-Mart.

It was the same as Mobil Delvac 1. Latest VOA says some tweaking may be going on. It doesnt have any Moly and has lots of ZDDP. Lots of guys already running Delvac 1 in bikes.

The 5W-40 yellow cap SUV oil is Delvac 1.

Among other things it has a slug of magnesium in it, which other Mobil 1 oils do not, to control soot (it's a detergent). Comparing it to Mobil 1 MX4T 10W-40 Motorcycle oil:

SUV Flash Point (ASTM D 92) °C 226
MX4T Flash Point (ASTM D 92) °C 253

SUV Pour Point ASTM D 97 ºC -45
MX4T Pour Point ASTM D 97 °C -54

There's a slight chance the magnesium could lead to spark plug fouling (which is no problem in a diesel) and the dedicated motorcycle oil possibly exhibits better low and high temperature performance.
