and the last one to show how a hockey puck (yes they are sold in East Texas of all places!) can be carved to fit the top of the jack stands available at Autozone.
On both my oil changes the amount came out the same to fill to the max line: Oil amount 4.73L + 946 ml + 280 ml.
In closing, I began to run out of patience toward the end trying to get the panel back on under the car as it is a little easier coming off in my opinion. Keep track of where the different kind of fasteners go, do not overtighten the plastic ones (why they are not all metal I do not know!), and the panel can be flexed to come out of the front and rear slots - however removing two fasteners on a panel just forward of the one you are removing makes the flexing less strenuous.
Overall time for me - about 5 hours. Glad I did it and will I repeat - yes.
