Does it matter what grade of gas I put in? I usally put Plus or Premium but sometimes when I'm on a budget I have to put in regular.... My fuel pump went out when my car only had 30,000 miles on it, it was horrible and I had to get it fixed for a pretty price... I wonder if what kind of gas had something to do with it....

Premium ONLY, dude. 91 octane or greater. Using the wrong gas doesn't effect the fuel pump, but it's bad for your motor.

Yes. Due to the Z's high combustion you can't use anything below 91. You are at risk of pre-combustion in your cylinder if you use 87. You need more octane in your fuel to avoid this. Defiantly never ever put 87 or 89 in it.
