2008 f350 6.4

[nocturnal30]

Hi guys i just got rid of my f150 and got an 08 f350. i must say its a beast. im here because i need info on engine oil. I live in south sask, canada and -40 in the winter is not uncommon. I was thinking rotella t 15w40 because i can get a 18.9 litre pail for $57. But it wont cut it prob in the harsh winter. I was also thinking rotella t6. heard good things. but friggin $40 per gallon here. any ideas guys????????

Congrats on the new truck! All I know using MN here I run 15-40 through the winter and so far so good. 4 years now. Book says 10-30 in the winter but I haven't and unless somebody talks me out of it I will continue to do so. The only towing I do is a few snowmobile trips in the winter

I use amsoil 5w40 and have done that since new. I have never had any issues with it. It is expensive though.

Thanks for the replies guys. im thinkin rotella t6 for all year round. But $40 a gallon and filter is $35. Pretty expensive. other route maybe rotella t or delo 400le until the winter hits and change to a lighter oil. ill have to figure it out today. going to city, live in the boondocks 115km from city so today is the day. Do you think 15w40 would be ok in -30 and colder? i called ford and he said everyone runs 15w40 and 10w30 in winter.

i decided for now to buy chevron delo 400le 15w40 , even that cost over $100 for the oil and near $40 for the filter.

I know Delo 400 is good oil, but for some reason I never cared for it in a Ford or a Cummins, only used it in GM Detroit's. Down here I run rotella 15 W 40 year round.
