Truck is a 2001 ranger 2wd v6. I'm going to do the rear diff fluid mostly because the guy i bought it off of did some towing and some camping...maybe some water crossings there might be milkshake inside i don't know so i'm just going to do it so i know its good.
Factory spec is 80w90, but i want to run a full synthetic as winters here on the canadian prairies can get down to -40 and stay there for two weeks straight.
I use my truck to get to work and back every day, which is a 15 minute drive down a country road. Truck doesn't see too much more action than that...maybe the odd highway trip every now and then.
Here's where i am hung up-there is no 80w90 FS available in my small town, but there is 75w90 OR 75w140. I don't want to overthink this too much, i just want something that is going to be close to factory spec while also having something that will be OK in the winter time.
