Ficm Voltage

So it was really cold out (21deg) and when I started the truck my ficm voltage was bumping between 45v to 46.5v, then after running for 5min it jumped up to 48v. Should I be worried about it? Thanks in advance!

I think you are ok the cut off point is 45v and under so keep your eye on it are you running a 5w40 Syn oil this will help on cold starts.

Ok good im trying to hold off on any mods till springtime. I haven't been running Synthetic because i couldn't find it in 15w-40. I use shell rotella but only find the 5w-40 T6? Have you had good luck switching to synthetic? I change my oil religiously every 3000k. I did flush my coolant and used Restore and Restore plus cleaned it out and switched to CAT ELC and installed a coolant filter. My Delta is 9*.

A 5w40 Syn oil is the only way to go your injectors will love it plus with the Syn 5w40 you can go to 5k on the oil change no problems.

The Rotella T6 5w40 synthetic is what you want.

What do you guys think about running 5W-40 in the summer? In the Owners manual it said its only good to like 60* ambient temps? I live in Mass so its not too hot for long but it can get warm...

Yeah, what 2 Stroker's link says. From -20F to over 100F. That's perfect for this Michigan boy.
