Yes, you missed the info. The answer to your question is well explained in post #2 of this thread.
At 6,000 miles on my car, I washed my car and decided to check on all fluids in my car and top them. When I checked my oil level on my dipstick, it was just above halfway. So, my guess is they may not have filled it up all the way from factory. So, I decided I want my oil to show full on the dipstick. I had a brand new 1 quart bottle of M1 AP 5W20 laying at home.
So, I poured half a quart of the M1 AP 5W20 in the car. I checked the dipstick. It was slightly above the maximum line. So, that is how I left it until 12,034 miles on odometer when I sent the oil sample to Blackstone.
I told Blackstone that I added half quart of M1 AP 5W20 at 6,000 miles.
I made sure to provide this detail here so people are not confused thinking this oil run was on M1 5W20 AP.
I hope this clarifies things to you now.
My car takes 0W20. But what I added was M1 AP 5W20.
I currently have M1 0W20 Extended Performance and Fram XG filter, both rated for 20,000 miles in the car. But I am planning to do another oil change at 12,000 miles again and I will send another sample to Blackstone to see what they say.
