Ken Burton wrote on Mon, 09 February 2015 05:02Guys, You are making this an unnecessary complex issue. The numbers and procedure I gave you is from my unmodified 455. The dipstick tube and dipstick on mine are still painted OEM blue. If you drain the oil and replace the filter, 5 quarts will fill it up to the full line. I use 1 quart of oil in 6000 miles so the oil is not being beat to death and foaming at that level. I have NEVER put 6 quarts in it and do not care to try it.
Having oil in an oil cooler or coolers does not really affect how much you drain because that oil is stuck after the oil pump and before being forced on through the filter and the engine. There is no path for air to enter that part of the system to allow oil to drain. So forget about that.
Drain the oil, replace the filter, and add 5 quarts of oil. Run the engine to fill the filter and shut it down. Wait 5 minutes and read the dipstick.
THAT IS THE FULL MARK.
Ken,
Here in comes the rub..
When I drain,replace the filter and refill with 5 quarts, that gets the level to just over the "Add" mark. If I add another quart to get to the stick's full mark, that quart is gone in less than 500 miles. It will take at least another 1500 to get to a 2 quarts down mark.
