I just checked my oil today and found it needed two quarts. I just put 2 quarts in it a couple of months ago. I dont drive it much. There is no oil on the garage floor where it sits all the time. It doesnt smoke and there isnt any on the bottom of the truck, that I can see. I use Mobil 1 0W40 like the manual says. I also haven't used any additives. Is this normal? Should I be using additives?
