Been to Chicago lately? My friend the MB Tech just got back a week or two ago and told me the same thing. He was telling me in a little different context. He told me that now I don't have to bring my own Mobil One at FSS time.
Is it pressure that is driving this change or is it that the dino oil is gunking up a little when stretching it to the FSS time? It seems like it was you that said that there were some engines seen gunking up a little when changing only at the FSS time.
We all thank you very much for keeping us informed.
Thanks and have a great day,
