Fruitmeister,
I'm doing the same except with 90/10. This weekend I will be installing a heat exchanger. So far over 10k miles on 3 cars. Now that everyone is going back to school, I expect 5000 miles a month between 2 cars.

One car had problems with injector coking. I suggest you pull one after 2-3000 miles and check.

As it gets cooler, I'l increase my RUG.

Keep us posted.
