I am considering a 2010 370Z. I have heard different opinions from different people. Some say the Z needs Premium gas (93) not Base (87). Some use 87. Which one is recommended and why? If using 93, does your car get better MPG due to the higher grade?
What upgrades can be made to get better MPG? Air intake? Or what? |

If you are worried about MPG don't get this car. This car is about going fast, having fun, looking good and spending alot on gas.

In regards to premium vs. regular, my Tundra definitely gets better MPG running premium. The costs of the premium gas + the more miles per tank I get is pretty much a wash compared to buying regular grade gas. A COI would pay off in the long run and should provide more HP...at least both are true with the Tundra. |

When I hear people talk about gas in any context I laugh b/c gas is one of those commodities that you will buy no matter what the cost ,my suggestion is to buy the car go FI and have fun but don't ever question gas again.

First off, max hp has very little to do with mpg's. There is no way in hell you're getting 16-17 mpg in a V8 Tundra at wide open throttle all the time for example. It all depends on driving habbits, and let's face it, you're more likely to want to hit the throttle a bit more driving a sports car. Basically, I've averaged anywhere from 30 mpg cruising on the highway, to 12 mpg with a stupid grin on my face. You're going to spend money on a car that has tires that last about 15k miles and cost about $1k to replace. The difference between using regular gas and premium gas is about $0.02 more per gallon....spending an extra $100-200 a year on premium fuel isn't something to really worry about. Just as an example, if you're driving a Civic and are on a budget & fuel savvy, premium fuel wouldn't have any real benefits for you since you're not really after the performance aspect. You're gonna drive that thing like a grandma to get the most mileage. The opposite is gonna be true (with me anyways), driving the Z. I always go with 93 octane and average 22-28mpg of mixed city and highway driving.

Yeah... I used to be a little concerned with mileage. Then I got over it. Then I bought a sports car. Then I thanked all the hybrid owners for saving more for me... especially after they make me follow them for 7 miles at 5 under the limit. Then they get real upset over the dead dinosaurs I just burned up passing them in a hurry. If only people drove the damn speed limit I wouldn't turn into such an ahole!
But I digress... if you can't or don't want to afford the "recommended" fuel, don't buy a $40k sports car. |

Listen dude, get the Z. I drive an F150 all day at the Pool company I run. When I get done work and get in my NISMO, my bad day just disappears. You having a truck too so let me tell you there is nothing more satisfying to tear up a back road on the way home after driving a big cumbersome vehicle all day. I really appreciate the car more to feel the agility and speed of the car. I know the Tundra is quick for a truck, but believe me it doesn't have **** on the Z.

This car is designed for premium fuel. Do not put 87 in it.

People that say the Z needs 87 are wrong.
Owners manual clearly states that premium grade is recommended and ONLY use regular for emergency, not extended period of time.

I dunno who these people are saying use 87, that almost sounds like a fairy tale. Now, I have heard of people putting 87 in and then having performance issues.
Without trying to sound like a douche nozzle, why look at a car that probably costs mid to high 20s if you're gonna stress about a couple bucks at the pump? And regarding upgrades to make the fuel mileage better? Well it doesn't make much sense to spend hundreds of dollars on parts to save a couple bucks either. |

The engine is already pretty efficient so your driving habits will have more of an effect on MPG than mods. Cooler air is nearly always a good thing, so some type of CAI may be beneficial. Using "thinner" lubricants in the engine, transmission, and differential can give some gains, but at the risk of poor lubrication at higher temperatures (eg, tracking - but if you're tracking, you're probably not too worried about MPG). Don't do this without doing a lot of research first. None if these will give big gains - the main thing is to keep an egg on the accelerator pedal. ![]() Edit: And don't run less than 91 octane except in an emergency. Put in just enough low octane fuel to get you to some 91 and drive like your Grandma until you get the good stuff.

Premium Mandatory? 370z requires premium fuel? If you use a lower octane fuel you will not be getting the performance gains of running a higher octane but your engine won't blow up, it will however develop a knock If you know anything about performance motors you want to run the highest Octane you can afford, not the lowest... ![]() |

Something interesting, Porsche (at least on the 991) runs temps of 210-220 for oil when in normal mode to reduce emissions and in turn (I think) increase gas mileage. When selecting sport, oil temp goes down to 180.
Higher oil temp apparently has something to do with emissions.
