Hope someone can answer a question for me. I have a new F250 truck with a V10 on order and I was looking at the service manual and it calls for 5W-20 oil and no others. My question is that I use Schaeffers 5w-30 snythetic blend in the truck I currently own and was wondering if this would work in my new truck. I really would like to use Schaeffers brand oil but they do not list a 5W-20 on their web site.Is anyone on here currently using anything differnt than the 5w-20 in their fords. Thanks in advance for any info !!
