Question 2

What happens if I accidentally put regular gas in a Diesel Fuel car?

Accepted Answer

If your car requires premium and you accidentally fill with regular, modern engines have knock sensors that retard timing to prevent damage. You may notice reduced performance and slightly worse fuel economy. Fill with premium on your next fill-up. This is a minor issue if it happens occasionally.

Question 3

Should I use Diesel Fuel in a new car to break it in?

Accepted Answer

Follow your owner's manual recommendation regardless of whether the car is new. Engine break-in does not require a specific fuel grade. Use what the manufacturer specifies from day one.

Question 4

What vehicles require Diesel Fuel gasoline?

Accepted Answer

Vehicles requiring Diesel Fuel typically include diesel trucks and commercial vehicles. Your owner's manual and the label inside your fuel door specify the required grade. Using a lower octane than required can cause engine knock and reduce performance over time.
