The engine has only had BP 10-30 since it was built, which was 146 runs before the 9 test runs. The VR1 went in at 155 total runs so it will start the year at 167 runs. Blackstone said "up to 20%" I doubt that I have anywhere near that cause I let it drip until it pretty much stops and that's with the front end up. I'm sure there's a fair amount trapped in various places, but 20% seems high.

That 20% might be a little low for Brad Penn. That oil is gooey and is stuck to everything. I usually run BP in all my motors, so at the tear down it is very messy. For better testing results you should have used an engine flush. Your results would have additional weight in making a very good determination.

I told Blackstone that I was going to stay with VR1 for at least 2 more changes to have a better chance of having all Valvoline by the 3rd or 4th oil change. I told them my plan was to do AAA-BBB-AAA testing instead of A-B-A.
