I'm not a subscriber. My limited budget goes into the car and into the house and the website, not into magazine subscriptions, though I am an avid reader. I do read the articles that are available online.

I fill mine with Turbo Blue 110 leaded whenever I pass a pump. 50/50 with super unleaded.

Citgo also has a 110 leaded racing fuel.
