How much are you 2.7 owners putting back in on refill after a change? Manual says 5.7 quarts. Are you always putting that much back in or are just putting in around 5.5 or just overfilling a little with 6?
Mine takes a little more than 5 quarts. That is right to the full line, not under or over. I use the wix filter.

My Dads always takes 6 quarts includeing what the filter holds. If you put 5.7 afer you run it and shut it off it is a bit low. We let it sit for about 10 minutes to drain back. His takes an even 6 quarts.
No! The more oil you have the more stable your oil temps. You also get a larger buffer for contaminates. I find it odd that most modern engines have such small oil capacitys. My Camry holds 3.9 quarts of oil for a 2.4 I4.
Part of that is also a buffer. Trucks often find themselfs in oddball attitudes not often experinced by cars. This epecialy true if it is a 4X4. Trucks are often required to hual heavy loads.
Unfortunately packageing on cars take priority over common sense. The oil pans and filters keep getting smaller on most cars with the exception of luxury vechiles and those recomended extended drains.
