6.6 liter gas oil change gmc at4 2500 

My 2010 ford f150 5.4 liter has a flood mode, you just hold gas petal down and turn key, it will not start up until you let off the gas, I watch the starter redistribute the new oil through the engine and filter, when guage goes up I let of gas petal and fires up at an idle, 600 rpms

Looks like you learned from your dad also, fill the filter and lub gasket with oil

Amen, 3300 to 3800 miles is enough for me

its just a shame GM makes no effort to support self servicing, including self reporting maintenance to carfax

8 quarts, my old 5.7 350 was 5 quarts

Where that oil leak was almost looks like a rear main seal leak....might be where your loss of engine oil whent to

I log all of my service with carfax
