I've been running Delo 400 Synthetic 5-40 in my Bobcat loader and am going to put it in my truck also next change. I have had good luck with the Delo 400 dino oils in my 6.0 and want the synthetic for the cold starts. Rotella T Synthetic 5-40 looks like a good price, but never have used it.

Is 2DLAKE your license plate? I thought I saw it on a Chevy or GMC truck, did you buy a Ford?
