Fuel mileage

Shoot, 150 miles on a half tank is doing good! You really need to compute your fuel economy - fill up the tank and zero out your tripmeter, drive it unti the gas light comes on, fill up, and divide your mileage by the number of gallons you put in.
Stock, a non-turbo gets around 17-18 city and 26 highway. My '86 base gets right at 19 city and I've seen as high as 29 highway. My '88 Turbo (with heavy mods) can get 16 in the city, but usually gets around 12 since I can't keep my foot out of it . I've seen around 21-23 on the highway in the car.
Yes, old spark plugs can affect fuel economy, but it doesn't sound like you have an economy problem. The RX-7 isn't the most fuel-efficient car on earth, BTW, but it does pretty well.

What size is our tank, 15 gallons(I forgot)? Think its somewhere close, so that means hes barely getting 10mpg. Very shitty IMO. Do a full tuneup and then drive around, shifting at 3500rpms or before(VERY difficult). Then you'll see the potential of your gas mileage.

Eh? Where are you getting the math - 150 miles on a half tank means 300 on a full tank. 15 gallons in a tank = 20 MPG, which is great.
The tank size is around 15 - it's 15 and some change, really. I think it's rated at 16, but 15 is the most I've ever put in.

My best distance on a full tank (usually fill up 13-14 gallons, 2-3 gallons left) is 250.
18mpg avg.

That is wrong, so very wrong. S4 is 16.6. That is what the Haynes morons had to work on. The S5 has a bigger tank. I guess I'll add this to my "Why the Haynes manual sucks" section.
