OIL LEVEL CHECK



Checking the oil level is one of the simplest and most important maintenance procedures. It should be done frequently because low oil level can lead to oil pan or even engine overheating and eventual starvation of the oil pump. This can mean inadequate lubrication and immediate, severe engine damage. Because the oil consumption of an engine can change quickly and unexpectedly due to leakage or changes in the weather, check the oil every time you stop for fuel.

If the engine has been running you must wait a short while to get an accurate dipstick reading. Allow the oil a few minutes to drain back into the sump before checking the oil level.

  1. Park the car on a level surface.
  2.  
  3. Raise the hood. Pull the oil dipstick from the engine and wipe it clean.
  4.

  1. Insert the dipstick into the engine until it is fully seated, then, remove it and check the reading.

The oil level should register within the crosshatch design on the dipstick or between the two lines, depending on the type of stick.

  1. Oil is added through the capped opening of the valve cover. Do not add oil if the level is significantly above the lower line or the lower edge of the crosshatch. If the level is near or below the crosshatch or lower line, add oil but do not overfill. The length covered by the crosshatching on the dipstick is roughly equivalent to one quart of oil.

Fig. Fig. 3: The oil level is shown to be at the lower mark. This indicates the need for about one quart of oil.

  1. If oil has been added, wipe and insert the dipstick to recheck the level. It is important to avoid overfilling the crankcase. Doing so will cause the oil to be whipped and become foamy by the rotation of the crankshaft. This will affect lubrication and may also harm the engine oil seals.

OIL AND FILTER CHANGE



See Figures 4, 5, 6, 7, 8 and 9


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.

After the initial (break-in period) oil and filter change at 600 miles (966 km), the oil should be changed every 7,500 miles (12,000 km)/6 months, whichever comes first. Under severe driving conditions (stop-and-go city traffic, delivery service, or in very dusty environments, etc.) change the oil and filter more frequently. Be certain to use a high quality oil and filter.

While some manufacturers have at times recommended the oil filter be changed with every other oil change during non-severe vehicle use, we recommend that you replace it any time the oil is changed. The added expense of a new filter is small when compared with the price of the parts it protects. The old filter may contain a pint or more of used engine oil and the added benefit of fresh oil is quickly lost if the old filter is dirty or clogged.

  1. Before changing the oil, see that the vehicle is situated on a flat surface with the engine warmed; warm oil will flow more freely from the oil pan.
  2.  
  3. Turn the engine OFF , open the hood and remove the oil filler cap from the top of the engine valve cover.
  4.  


CAUTION
Hot oil can burn you. Keep an inward pressure on the plug until the last thread is cleared, then, quickly remove it.

  1. Place a container under the oil pan large enough to catch the oil. A large, flat drain pan is the most desirable.
  2.  
  3. Remove the oil drain plug. Allow the oil to drain completely.
  4.

  1. When the oil has finished draining, install the drain plug, then tighten until just snug. Use a new washer (if applicable) on the plug.
  2.  
  3. Move the oil drain pan or use a second pan under the oil filter; the filter retains some oil which may drain when it is removed.
  4.  
  5. Using an oil filter wrench, loosen the filter, then unscrew it by hand.
  6.

  1. Using a clean cloth, wipe the filter mounting surface of the cylinder block. Apply a thin coat of clean oil to the new filter gasket and install the filter. Only use filters which have an integral bypass.
  2.

Hand-tighten the filter only; DO NOT use a filter wrench for tightening. If the filter has instructions printed on it as to how far it should be tightened (for example1/2or3/4turn), mark the filter, then tighten it accordingly.

  1. Remove the drain pan from under the engine.
  2.  

Used engine oil is an extreme environmental hazard. Proper disposal of used engine oil is very important. Rather than dumping the oil in storm drains or throwing it in the trash, you should take it to an approved recycling center. Many shops will accept used engine oil. If you are uncertain where to take the oil, many local municipalities can direct you.

  1. Add the correct amount of recommended oil into the filler hole on top of the valve cover. Be sure that the oil level registers near the full line on the oil dipstick.
  2.

  1. Install the filler cap. Start the engine without touching the accelerator pedal and allow it to idle. The oil pressure light on the instrument panel should go out after a few seconds.
  2.  
  3. Run the engine for 1-2 minutes and check for leaks. Turn the engine OFF , then, after a few minutes, recheck the oil level; add oil. Be sure to check for oil leaks. If you find any, correct them immediately.
  4.  
  5. Recheck and/or refill the engine with oil.
  6.  

If the filter leaks, make sure the old filter gasket is not on the mounting flange. If the old gasket is not on the flange, tighten the filter a little more. If it still leaks, try another filter.
