Four quarts PP 5w20, 2 quarts PP 5w30. No make-up oil added.
"you've run this oil more than 10,000 miles, and wear is as low as it has ever been....The oil could actually have been run longer. Impressive!"
10,171 on oil, 49,533 on engine. Motorcraft FL820S filter.

SUS viscosity at 210F 53.4 (expected 46-59)
cSt viscosity at 100C 8.31 (expected 6.0-10.2)
Flashpoint 400 (expected >355)
fuel Insoluables 0.2%
PP does well at double the suggested mileage for this engine in my Gramp Marquis. 95% highway cruising at 72-78 mph. A couple of 100mph short runs...you have to let these cars "stretch their legs" every once in a while B-)
