Hey there I'm new here.
Has any one here used this oil Ridgeline 15-40w. We have it at work and was just curious about it. I'm using it in my Duramax right now it seems to like it.
Thanks
I think the only thing that I don't like is it really brings out the tick, but mind you I only have 700k on the oil. Oil pressure once warmed up is about 200kpa/25psi driving at 100kph.
