Schaeffer's 5w-40 year round and no problems at all and we will see in about 3000 miles for a sample to see what's going on. When I decided to go this route I tried rotella 5-40 and mobil truck and suv 5-40 and the schaeffers is the same price as the rotella as long as you don't pay for shipping which is about $13 a gallon and well worth it to me.
