White in winter. Gray when gelling is not an issue.

 

I use a 2:1 mix of power service (white or grey) and MMO. Coming up on 30,000 and no problems to date.

 

1 quart of 2 stroke oil per fill up. Or roughly 1oz per 1gal!!

 

2 cycle oil is the best additive for diesel engines... I've been running it now for about 20K miles without a problem...

 

nothing in mine

 

I've started to use 10oz PS and replaced MMO with 16oz of 2 cycle oil so far it makes the engine much quiter in the nice warm -08 to -18 below zero temps we've had this last week. I still have just over 6 jugs of PS winter formula to get used up

 

Me too, with a little 5w30 oil mixed in. My truck has them rotary pumps. I feel I need the extra lube in the system. Original VP44 and on my second lift pump. 167,8xx on the truck.
