I had a 85 GSLE with the 13B and the mileage was terrible and the car wasn't
nearly as fast as my 240. I got 18 mpg on the highway and even less in the
city. I brought the car to a rotary expert and he said it was normal. Plus
the engines are usually wasted at about 80,000 miles as the apex seals die.
510s don't have frames under them so it's easier to play with.
