AGE Mechanic,
Don't mean to be smart... and not sure if your speaking to me since I was the last thread poster, but the guy who started the thread asked about oil.... then the same guy switched questions as asked about transmission and Tow/Haul?
Obviously, the topic changed and those of us with experience or an opinion freely gave it....
Yes, your right... Tow/Haul has nothing to do with oil!!!
But Tow/Haul has everything to do with the current topic or the original poster's follow reply & question.
Have a good day (or night).
Thanks,
