I understand another plus is the oils ability to protect flat tappet camshafts.
Having said that how often are you changing your oil? |
A J- I checked the screen after every event and change the
oil every other. That could amount to ~200 miles for the Cobra and ~40 miles for my dirt engines. I ran the 1st Cobra engine 3500 miles, turning it 7200, replacing only valvesprings every 1000miles, and it looked new inside upon teardown.
Brad Penn 20W-50 ("the green oil") is the same oil that Kendall GT1 20w-50 (the original "green oil") used to be.
