I've read several places recently that it is "recommended" to put 92/93 octane fuel into Neons with DOHC engines. Has anyone done this, and does it really make a difference? I always heard that almost 100% of cars are fine with Regular fuel.
When I used regular gas my mileage dropped about 6-7 mpg.
Chryslers recommendation for premium fuel is for better mileage and higher horsepower numbers.
Not any car. 93 octane is not recommended for the SOHC engine, only the DOHC.
To achieve optimal performance in the DOHC engine, 93 octane is required. You technically don't have to use it, but some people have posted about pinging problems while running a lower octane. I personally didn't experience problems while using a lower octane, but I would not rule it out.
