Man.. gas prices are killing me.. I'm getting ready to go back to school and school is 22 miles away from my house... would i be able to put half 93 octane and half 89?? what can happen if i do this?? otherwise i'm going to be driving with my girl on her Toyota Corolla every day.

Thanks

 

your car would probably perform like crap but I think it would still run. Honestly though, if gas prices affect your bottom line that bad cuz you're a student you DEFINITELY don't need a $30k car $3000+ worth of mods.

 

That would give you 91 octane... the same octane premium gas available in CA and meeting the Nissan spec.

 

Well... i won't really care about how the car would perform for right now.. but i'm concern if the car is going to be affected in any other way... like breaking down or get something. ohhh by the way.. the $3,000+ wheels were a gift for being a good student.

 

Nothing bad would happen, car would read that lesser quality gas in and adjust, just loose performance. Even though 93 and 89 would = 91... which is what i put in everytime because on the west coast, best you can get, unless want to pay for 101 haha.

 

Big 2nd. We sound like asses saying so, but if you're having trouble putting gas in your car, how are you going to afford maintenance? Tires? Are they going to be gifts too, so long as you're a good student?

Mixing 93 and 89 is a baaaaaaad idea. If it was me in your situation, I'd borrow another car if possible...I'd do anything to keep from putting less than the best gas available in my car. Despite what some people will say, the Z was designed to run on 93 octane. It can run on 91, but your car will not be happy, and neither will you. Kinda like drinking your own urine to survive when you run out of water.

 

93 is needed if you dont want your engine to knock at high RPMS. So keep your RPMS low and you should be alright. Most newer engines have knock sensors, so if thats the case with Z, you should be fine.

There was a comment by Porsche design engineers that Carrera should be able to run fine if you use low octane gas, but wont get the published numbers on performance.

Octane is to prevent knocking, not to directly increase HP. Higher octane gas will burn slower than lower octane one.

 

I would try to stay on 93 all the time if I were you. The lowest I would ever put would be 91, that's only if I was still NA. But, try to stay on the low rpm range and avoid punching your gas padle hard, that'll save you some gas.

 

ohh..

 

Why do threads like this continue to get posted? There's only 10 cents difference between the grades and at 15 gallons you save a whopping $1.50. You want to run on a lesser quality gas to save less than $100 a year and in your case, wanting to mix the gas to save less than $50 a year? How do you guys end up in Zs? Sell your wheels. It'll make up the difference in what you save for the next 20 years.

 

haha gotta love houston people.

BTW TK2005, you found your Z yet or still waiting? I am still waiting for the right Z

 

Tell it like it is brotha!

 

Ouch, you guys are harsh but then again, you speak the truth. Gotta give it to ya

 

unless its like europe where they do it by the liter instead of gallons or something then yeah.. you can B****... at this point everything is high from what it use to be. i can have a group buy of some sort if you come by gas at my parents gas station :P

 

Higher octane gasoline is a waste of money

It's ture guys, read this. The oil companies have you fooled. They just want your money. It's a scientific fact. Gas is Gas, your Z will run fine on 87 octane.

Unless your engine is knocking, buying higher octane gasoline is a waste of money, too. Premium gas costs 15 to 20 cents per gallon more than regular. That can add up to $100 or more a year in extra costs. Studies indicate that altogether, drivers may be spending hundreds of millions of dollars each year for higher octane gas than they need.

Will higher octane gasoline clean your engine better?
As a rule, high octane gasoline does not outperform regular octane in preventing engine deposits from forming, in removing them, or in cleaning your car’s engine. In fact, the U.S. Environmental Protection Agency requires that all octane grades of all brands of gasoline contain engine cleaning detergent additives to protect against the build-up of harmful levels of engine deposits during the expected life of your car.

Also read this:

Consumers who were exposed to ads that claimed that Exxon high octane gasoline would reduce auto maintenance costs will get important new information from Exxon soon. In a landmark settlement of Federal Trade Commission charges that the ads were unsubstantiated and misleading, Exxon will run an extensive consumer education campaign, including television ads throughout the United States. The message of the campaign will be that the right octane for most cars is regular octane, and most cars will not benefit from more expensive high octane fuels.

Naaaa, I quit looking. Since I am not too concerned about color or trim level, I'll just get whatever leftover 05 there is in December. I am kinda debating getting one at all. All these posts about problems and people that supposedly "love" their Zs are just dumping them left and right.

 

What kind of gas do you put in your Z? Hmmmmmm? That's what I thought.
