What are the danger .... 87 Oct in the '11-12 370Z
Wife and I are both retired, and have been (long distance) motorcycle touring since '01. We are considering doing the same thing in a 370Z roadster.
What are the repercussions of using regular fuel in the '11 -'12 370Z Roadster. on a regular bases at various altitudes across the country....??? Thank you for any info......!!!!

Often times using regular fuel results in degraded fuel economy, so sticking with premium can actually be cheaper.

Possible undesirable outcomes include:
1. Detonation under load, which could damage the motor. 2. Reduced power, if the ECU detects pinging and retards spark in order to save the motor. Not advised overall. Somewhat less of an issue in altitudes well above sea level (e.g., Wyoming), but again, not advised overall. Use at least 91 AKI.

Pretty much everything has been stated, but the motor will save itself with retarded timing and decreased performance. Overall, not worth it.

I agree with all of the warnings above.
Also, a few years ago, I thought I'd try this in my '00 Celica GTS. I did two different experiments and they both showed the same results. I dropped to mid-grade for one experiment and to regular for the other. The mileage dropped so drastically that it was costing me the same or more as using Premium. Most important on the warnings is the fact that it can actually damage the engine. High compression engines need hi octane fuel. Don't skimp to save a few pennies. |

what about running a regular/mmt/toluene mix you can buy the chemicals to make your own 97octane for the price of premium gas.

Run premium gasoline- It's better all the way around, and you'll have no issues no matter what altitude.

don't cheap out on gas. its a 40k car. and like said above, its $5 per fill up. yes, gas in general is expensive, but premium gas isn't really that much more expensive than regular.
Assuming you put 12,000 a miles a year on the car, and assuming the car gets 20 miles a gallon, thats 600 gallons of fuel per year. Assuming a delta of 20 cents per gallon between regular and premium, that is $120 PER YEAR difference between using premium and regular. You and your wife can just like, eat taco bell instead of going out to dinner like once or twice and that pays for your gas. its such a small difference if you think about it, which is why it always irks me when i see people putting 87 in their cars that reqiure premium fuel. Technically the reason why you don't want to put regular instead of premium is because our engine runs high compression. Lower octane fuel will combust sooner and less consistently than high octane fuel. So the fuel will basically combust before its supposed to causing knocking and damaging the engine.

If $120 more in fuel costs over a year is a deciding factor for someone, they need to re-evaluate their car purchase. You could look into a Flex Fuel adapter for the car. E85 is currently around $1.50 cheaper than premium gasoline. Filling up my Ranger costs $15-20 less than a pit stop in the Z. Corn gets a few miles less per gallon than dinosaurs, but it is reported to make more power. Of course, there's also the added expense of modifying the car in the first place.
