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

Answer 1

There are many different opinions about what gasoline to use for a car that is a V6 and not a performance V8. Here are some of them:

• 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.

• 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.

• 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.

Not a performance vehicle who cares use any.

• A high octane gas is important to put in your car about once a month though or it will hurt the car because of a water build up from the lower quality gas. also bp gas has been proven iin scientific tesing to be the best quality gas you can buy in america.

• All great facts, but to get to the point. Higher (top end) cars use premium gas because the compression ratio is higher, this helps burn more fuel at a higher flash pont (temperature gasoline ignites). Therfore, using premium gas in a V6 or V8 differs depending on the make and model of the vehicle. Oh yeah, and putting 92 octaine gas in a vehicle not recommended for will not increase power.

• Premium gas was specified in the question, so octane is not the issue. Major brand premium gasolines are virtually identical, so there is no advantage in using one brand over the others. There isn't enough data to confirm the statements about BP and Chevron.

I have a Honda Accord and it is a V6. I always go to Chevron. Do not go to a Costco, Valero, Exxon, or anything other than a Chrevron. If you don`t go to Chevron, sometimes your car might not be able to start and you will have to rev it a little bit.

• 7/23/09 I saw a ABC documentary why gasoline price changes so fast. In this documentary, a gasoline wholesaler said that since Federal Regulation dictates how gasoline is formulated, all gasolines brands are the same. He sells to Shell, Cheveron, Valero, etc. All big name tankers and small name tankers buy gasoline from him. I buy the cheapest and every two month put a can of BG product to keep fuel injectors clean. By the way, gas prices changes quickly due to wall street speculators.

Furthermore according to the documentary the only difference in gas quality is the money an individual gas company will spent to convince you of the difference. Gas is a lot like tires if you put 300$ tires on a car or $3000 tires on a car a person who knows nothing about tires will never know the feeling/ difference the quality should have made.
