Due to their high compression combustion, diesel engines require their own type of fuel. This diesel fuel oil is available in three grades, depending on the temperature.
The important difference in gasoline isn't who sells it, but what the octane level is. A higher level of octane can reduce or even eliminate engine knock, a problem caused by uncontrolled combustion.
The engine oil you select is very important. It lubricates, reduces heat, quiets engine noise, fights corrosion and with the help of the oil filter, removes dirt and particles.
When it comes to filling your gas tank, leave a little room for the tank to breathe. Continuing to fill the tank, after that first click of the nozzle when the pump shuts itself off, allows raw gas to enter the car's vapor recovery system.
