Rotella T5 10W30 ok for towing :dunno:

[Articcatzl440]

i was wondering i have t5 in both my EX and F350 and both of them are going to be hauling campers. the ex will be hauling a bumper pull at 7800 pounds will t5 be ok for that??? and the 05 is going to be hauling truck camper and boat like 5000 pounds. again will t5 be sufficient or should i go back to 15w40

I'd go for 5w40, recently switched mine. Easier cold starts, same viscosity at operating temp.

Ill second that. My truck LOVES the T6 (Synthetic) over the T5 (Blend).

i'm currently running the 10w-30 only because it started easier in the cold than the 5w40. But i'll be switching back to 5w-40 amsoil synthetic in another month. You'd be fine with the 10w-30 tho.

5W-40 would be better for the summer.

Really? 10w-30 starts better than 5w-40?

To actually answer your question, yes you will be fine hauling with the T5 if anything it will be better than running the regular 15W40.

yeah, it's thinner than the 5w-40. There has been lots of testing done on most 5w-40 synthetics. Just after about 1000 miles the 5w40 sheers down to a 30 weight oil. Where as the 10w-30 up to at least 4000 miles is still 30 weight. I know a bunch of guys in canada actually run 0w-30 in the winter.

i run Amsoil 5w-40 all year long !!!

I was running T5 for the winter and recently switched over to T6. I thought the 10-30 was only good for the colder weather, 60 degrees F. Anything warmer than that it was recommended to go with a 15 or 5w-40. I thought this would only be amplified while towing. This is my first oil change with the T6 though. I had previously been running only Motorcraft 15w-40.

i have heard some guys running amsoils 5w-30 synthetic year round.
