Hi all, i just purchased a 2008 crown vic police interceptor with the 4.6L v8. The car was an unmarked unit and has about 155,000km/96,000m & 1800h on the idle meter. The owners manual calls for 5w20. I live in toronto ontario, Canada. The car will see mainly highway and will be driven hard. I know i will be using a motorcraft fl820s but im not sure about conventional 5w20.....I was thinking about a high mileage 5w20 or conventional 5W30. I appriciate all and every opinion.
Thanks in advance
