Rotella 5w40 in Ford Ranger?

[dsmith41]

I am thinking of switching oils and Rotella is what I would like to run. The thing is, my owners manual calls for a 5w30 weight oil. It is a Ranger with the 4.0L SOHC.

Where I live in Nebraska, we get temperature extremes. It can be 100 degrees in the summer and it can be below 0 in the winter. Is that 40 weight oil at operating temp going to be too heavy? Is anyone else running Rotella T 5w40 in there Ranger? Thanks!

Mobil 1 5w30 Extended Performance. My sons 91 Ranger has 330,000 miles all on M1 at 10- 15,000 OCIs.

Either EP like tig said or RTS would work great in that truck

I'm running RTS in my '90 Bronco 2 2.9v6.

I used to run it in the winter and Mobil 1 High Mileage 10w40 in summer.
But the RTS seems to do very well year round.
(even in the NewMexico desert heat.)

Use the RTS and sleep well at night!

You can use RTS without any problems.
