No, you don't have to. I use regular fuel in my 2006, and it continues to get a clean checkup every time I take it to a body shop.
every car that was designed to run on unleaded fuel can be ran on reg. unleaded fuel,it just will not make as much power and or run as smooth as with premium fuel
Other threads on here have shown that you can run on a lower octane. I have owned 2 MDXs and run mid-grade (89) in both with no issues.
Manny high performance automobiles require premium fuel. Most United States domestic family automobiles do not require premium fuel and will run fine on 87 octane fuel.
you should run premium gas.
All Subaru SVX engines were designed to run on premium fuel of 93 octane.
The 2002 Nissan Maxima runs on premium unleaded (required).
Yes
yes, but they require that you only run Premium fuel. The savings on mileage is offset by the extra cost of the fuel, and its not worth it.
Yes, but it will not continue to run.
Replace the head gasket with a thicker one, this would lower the compression ratio.
It is recommended and you might get better performance and more life out of it. But you can run regular fuel in it
Sorta. You have to run premium gas in it at all times. Failure to run 91 octane or above will result in the car getting very bad gas mileage, run very badly in general, and can damage the engine. It technically burns any type of gas that would be used in it, but it does require premium gas to operate. That's why it states on the dash premium fuel only.
