Really wasn't sure where to post this, searched and didn't find anything...
Avis used to give a standard 500 miles per rental, and as a gold it was 1,000 miles per rental. That was a pretty good value. I rarely check my account, but it looks like this is no longer the case. The last few rentals have given 4 miles per base dollar (and equal loyalty points). Anyway, figured I'd post this for anyone working off the past earning rates.
(I did find this page which promises 750 miles for using the Barclay Aviator card:
