I purchased my truck new and have done 2 oil changes myself. In both cases I drained on a level surface (my garage floor - very slight slant towards rear of truck) and let it drain to a slow drip. 12 quarts of oil were then added. Each time resulted in the dipstick reading high as shown in the photo. Couple additional thoughts:
- I believe the dipstick showed the same level for the factory fill. I'm about 90% certain on this.
- One of the other forums mentioned that these trucks are very sensitive to levelness as far as the dipstick is concerned. My truck has the air suspension and sits about 2 inches lower in the rear than a truck with standard rear suspension. I jacked the rear of the truck up a couple of inches but there was no appreciable change in the dipstick reading.
- My understanding is that the safe range on the dipstick represents 2 quarts. If so, I'm about 3/4 quart high. Is this even a concern?
- Could the dipstick itself be off in its length?
