hey all, I was wondering what the size of the gas tank on my Z24 is? also what's the best kind of fuel to use? would premium over regular really make much of a difference? thanks.

I'm guessin your tanks is 14 Gallons.Not sure on that one. A friend of mine Ran 93 in his car for 2 years straight and lost the injectors. The dealership said they burnt-up from the constant high octane level. I run 89 3 weeks a month and 93 the last week. I notice better gas milage with the 89 as compared to 86-87 Octane. The 93 once a month along with a 1/4 of a bottle of 70% rubbing Alcohol every 3 months keeps the internals pretty clean.

Some where around 14 gallons. I have pumped in about 13.8 gallons after I have run on E for a while. Not really a good idea to do that though.

I always use 87, or 89-90 with ethanol, whatever is available. Seems to run the same on either.
