3BarBoost--This is our 3rd oil change. Still
will get oil change at dealer. But, I would really
like to switch to Synthetic. Our daily driver uses
Royal Purple 10/30. It seems to run smoother-certainly runs cooler because it idles a lot. Seems
to me it would work even better in the more hostile situation of the turbo. Stop and Go traffic. Can you please comment? H.
