Which brand-name for premium gasoline should you use for a car that is a V6 and not a performance V8?

Answer

Most turbocharged or other vehicles requiring higher octane fuel will lose power and economy as part of the computer's strategy for using the low-octane fuel safely. Also note that many Nissan vehicles will turn on the check engine light when they use low octane fuel.

Answer

I have used Chevron gasoline for many years. There is a notable difference in warm up time, idle smoothness, off the line response, performance at speed and of course passing power. I occasionally fill up with an off brand or even a name brand other than Chevron and I can always tell the difference.

Answer

Few V-8's and even fewer 6's require premium gas.

You gain NO additional power using premium. Octane is simply a measure of the fuels resistance to knock (also known as pre-ignition).

The higher the compression of the engine, the higher octane it needs to avoid "pinging". If your engine doesn't ping under heavy acceleration on regular (87) gas, you don't need anything with higher octane.

Plus, cars made in the last 5 years adjust the timing automatically if pinging is detected....so even when the manufacturer might recommend mid or high octane, you won't hurt the car using a lower grade...you'll just lose a little bit of power.
