Just changed the oil on my 460 truck today. I have the opposite problem. Dipstick reads full at 5.5 quarts.

Vivek, did you happen to read this? It was not uncommon for the dipsticks to not be accurate for a specific engine.

Yes I saw that the other day. I have a mental note now on where the dipstick needs to be when filled with 6 quarts. I do need to actually mark the dipstick though as you had recommended.

I have given the benefit of doubt in the past to things like parking level, oil level when hot vs cold but I think its good to baseline it once and hold things to it.
