Every time you stop for fuel, check the engine oil as follows:

  1. Make sure the car is parked on level ground.
  2.  
  3. When checking the oil level it is best for the engine to be at normal operating temperature, although checking the oil immediately after stopping will lead to a false reading. Wait a few minutes after turning off the engine to allow the oil to drain back into the crankcase.
  4.  
  5. Open the hood and locate the dipstick which will be on either the right or left side depending upon your particular engine. Pull the dipstick from its tube, wipe it clean and then reinsert it.
  6.  
  7. Pull the dipstick out again and, holding it horizontally, read the oil level. The oil should be between the FULL and ADD marks on the dipstick. If the oil is below the ADD mark, add oil of the proper viscosity through the capped opening in the top of the cylinder head cover. See the Oil and Fuel Recommendations chart in this Section for the proper viscosity and rating of oil to use.
  8.  
  9. Replace the dipstick and check the oil level again after adding any oil. Be careful not to overfill the crankcase. Approximately one quart of oil will raise the level from the ADD mark to the FULL mark. Excess oil will generally be consumed at an accelerated rate.

Under normal operating conditions, the oil is to be changed every 7,500 miles or 12 months, whichever occurs first. Change the filter at first oil change and then at every other oil change, unless 12 months pass between changes. However, for best protection against premature engine wear, a new filter should be installed with every oil change.

If driving under conditions such as: dusty areas, trailer towing, idling for long periods of time, low speed operation, or when operating with temperatures below freezing and driving short distances (under 4 miles), change the oil and filter every 3,000 miles or 3 months.

The oil should be disposed of properly after it is drained from the vehicle. Store the oil in a suitable container and take the container to an official oil recycling station. Most gas or oil and lube facilities will take the used oil at little or no expense to you.

  1. Raise the car and safely support on jackstands. Remove the oil pan drain plug and drain oil into a suitable pan.
  2.  


CAUTION
The engine oil will be hot. Keep your arms, face and hands away from the oil as it drains out.

  1. Using an oil filter wrench, remove the oil filter and place it in the oil catch pan. Using a clean rag, wipe oil filter mounting surface.
  2.  
  3. When installing the oil filter, place a small amount of oil on the sealing gasket and tighten the filter only hand tight or 3 / 4 of a turn past gasket contact. Do not overtighten the filter.
  4.  
  5. Install the oil pan drain plug and torque to 18 ft. lbs. (25 Nm).
  6.  
  7. Using a funnel, add oil through the oil fill cap. Lower car, start the engine and inspect for oil leaks.
  8.  


CAUTION
The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.
