You need 15w-40w.

Use Shell Rotella or Valvoline Blue.

T6 Rotella synthetic 5w40 in my newer diesels. Rotella T5 15w40 in the older ones.

15 W 40 is the one for a normal climate , when it gets colder you go for the wider range , however most of the new Yammers take 5 w 40

Just got the hook up from a new friend who owns a boat yard here set me up with $3.50 a gallon fuel cost at the fuel dock.

He has a 46' Ocean nice lines.

Going out tomorrow Mako tagging then teaching a friend with a 63' x 23' dive research boat dive operation how to hunt Threshers.

Also have some Reconisis recovery mission that should be interesting.

Good luck.
