i think i will try the shell rotella after all what can it hurt. i have seen it before but never used it. i guess i can just get sae 30 wt. i wil let everyone know how i like it. i would say i'm about a month from start up. the bottom end is almost done. the head and extras to go. i also have to have the trans checked and install a new gas tank, mabey a little electrical stuff. at least the brakes and bearings are done- this truck has set for several years. i bet it's 2 months at least before its on the road, who knows that ice storm really set me back. thanks to everyone for the help.
