Does Premium Gas really make a Difference?

“Does Premium Gas really make a Difference?

 

 Welcome to Mercie J Auto Care, Where Compassion and Craftsmanship Come Together. I'm Rick Smith, ASE Certified Master Technician.

 

The higher the octane rating of fuel, the slower it burns.  Fuel in the engine does not actually “explode”, it burns across the top of the piston.  If it is too violent, then we have a knocking or pinging noise which is the piston rattling around in the cylinder.

If you have a high performance vehicle like a corvette and it calls for a certain octane rating, then you don’t have a choice.  For most of us though, how do we choose?  We want a slower burn under high temperatures, but when it’s cold out, we will actually have higher horsepower and fuel economy with a slower burn.  In my GMC truck I run high octane when the temperatures here in Mesa Arizona are above 100 degrees, but during the winter I put low octane in my truck and my wife’s Honda Pilot.

 

Don’t get worked up over mixing fuels with different octane ratings.  It won’t cause any trouble if you have to go back and forth.
