Three Things I guess.

First off. My 1991 RX7 non turbo, when at full temp rests around the 3 quarter mark on the temp gauge..Is that about right.??

Secondly. I bought it off a gentleman who stored it in winters. Didnt get to drive it much thus far due to parking restraints. When I started it up for probably the tenth time the day after I bought it, it blew some blue smoke for a couple seconds...Is this normal as well???

And I guess last but not least..At the prices these days for gas..Is it essential to use premium or is regular o.k....?

3rd day owning the car and IN LOVE...coming from 3 diffrrents civics for the past 5 years....what a diffrence...Absolute diffrent car.

The stock gauges have three "zones": Cold, warm and overheated. If the needle is not burried on one extreme or the other, it's probably "normal". If you are paranoid, the only option is to buy an aftermarket temperature gauge, which would operate linearly. Just note that if you place the sender anywhere other than the stock location, the gauge will read different.

It's not necessarily unusual, but you want to keep an eye on that. They tend to smoke a little bit when you cold-start them (just a puff; not something you could, say, see in your rear-view mirror). And, the smoke could be either fuel, oil or coolant. Coolant smoke would be white. Fuel and oil are harder to distinguish. Fuel smoke makes sense when starting the car, particularly a warm-start. That would indicate your fuel injectors are leaking a bit...a common problem on 2nd generation RX-7s. Two fixes: get the injectors cleaned or install a fuel pressure bleed-down kit. If it's oil, that would indicate your oil control o-rings are going bad, but that usually shows up at high-RPM when you let off the throttle and the chambers go into a strong vacuum, sucking the oil past the o-ring and into the chamber where it burns.

Actually, it's best to use "regular"! The only advantage of so-called "premium" fuel is the high octane rating. Octane is the resistance to knock, or detonation. A properly tuned non turbo rotary engine is not at risk of knock, so you want absolutely the lowest octane you can find.
