hey guys wanted to get some opinions on what oil i should use for breaking in my new motor. it’s a stock s5 6 port and i didn’t replace the bearings. i’ve heard many mixed opinions but the one thing ive heard pretty consistently is use conventional not synthetic. any suggestions?

 

Simple conventional 20w50, I start up an engine and run it up to temp for 5 minutes - drain and inspect oil and element. Refill with the same oil and replace after 500 miles.
