Over a long period of time in my 08 350z.

 

As long as you add some sugar with each fill up, your car will run just fine.

 

Smh your car is going to run like ****. And long term use will result in a major **** up.. just don't do it man

 

gas is so high though. 4.28 a gal. and regular is 3.91.

 

Think of it this way. It's only $3-$5 more a fill up to avoid a major and costly repair in the future.

 

Here is what you do, sell your Z and buy a Honda Civic. Then you can use all the regular gasoline you want.

I don't know why people want to cheap out on such an expensive asset.

When you bought the Z, you obviously weren't interested in MPG.

 

 

I/we feel bad for you but you have only a few choices. Since our President wants us off oil & drive electric cars, maybe you should listen to your president, sell your car & buy a EV. You can pay the higher premium price & just have good thoughts like at least I'm paying this price, not next year's even higher price. You can also not vote for Obama & vote for someone else that is ok with gasoline. Oh, I forget, it's too late, he won.

 

Should have given this some thought before you bought a Z.
In short term situations,regular is ok.The car was not designed to
run on regular.Use premium only or you will screw it up big time.

 

Lol please sell it

 

Well said.

 

... dear lord.

 

cmon man

 

Leave it to Andre to turn this political, ha ha ha ha.

OP, quit being cheap.

 

Its fine, you can use bleach as an octane booster. Fill up a 20oz soda bottle with bleach and add it to a full tank, you'll be good to go.

 

Regular gas doesn't harm the engine in any way there are plenty of people that have run regular 87 since buying their cars new on 03. Lol at the people that think it'll harm anything. You might lose a little power but its not that noticible also you get slightly less mpg most the time 1-2 mpg

 

 

if you bought it new you should use premium. If you bought it between like 2007 and 2009 it's okay to use mid grade. If you bought it in the last couple years, just use regular.

 

Engine will blow up if you use regular fuel.

 

One of the few smart people on here, but MPG actually stays the same of not slightly better. The one thing that is fact, plugs will wear out faster. Before my car was tuned and what it is today, I used 87 for long freeway trips.
