Gasoline engines are required to use engine oil meeting API classification SH or SH/CC or SH/CD. Viscosity grades 5W-30 or 10W-30 are recommended for the Tempo and Topaz. See the viscosity to temperature chart in this section.
Diesel engines require different engine oil from those used in gasoline engines. Besides doing the things gasoline engine oil does, diesel oil must also deal with increased engine heat and the diesel blow-by gases, which create sulfuric acid, a high corrosive.
If your vehicle is equipped with a diesel engine, be sure to check your owner's manual for the recommended oil viscosity to be used. Many manuals have a diesel engine supplement.
There is a myth that synthetic oils cannot be blended with traditional type oils. This myth is FALSE. Although a car may leak a synthetic oil at a slightly faster rate, synthetic oils oils do not burn any faster than traditional oils.
OIL LEVEL CHECK
See Figures 1, 2 and 3
It is a good idea to check the engine oil level every time you fill your gas tank.
- Be sure your vehicle is on level surface. Shut off the engine and wait for at least 5 minutes to allow the oil to drain back into the oil pan.
- Remove the engine oil dipstick and wipe with a clean rag.
- Reinsert the dipstick and push it down until it is fully seated in the tube.
- Remove and check the oil level indicated on the dipstick. If the oil level is below the lower mark, add one quart. Wait several minutes, and check level again. Add enough oil until level is at the top mark on the dip stick. Remember, add oil in small amounts. It is easy to add more oil, but much harder to take it away.
OIL AND FILTER CHANGE
See Figures 4, 5, 6, 7 and 8
The recommended engine oil and filter service interval on your vehicle is every 3 months or 3000 miles (which ever comes first). If the vehicle is operated in severe conditions, more frequent intervals may be required.
- Make sure the engine is at normal operating temperature (this promotes complete draining of the old oil). Make sure engine is OFF.
- Apply the parking brake and block the rear wheels. Raise and support the vehicle safely.
- Place a suitable drain pan (approximately a gallon and a half capacity) under the engine oil pan drain plug. Using the proper size socket and rachet or wrench if necessary, loosen and remove the plug. Allow all the old oil to drain out. Wipe the pan and the drain plug with a clean rag. Inspect the drain plug gasket for signs of distorting, replace if necessary.
- Reinstall drain plug by hand and tighten with a wrench. DO NOT OVERTIGHTEN.
- Move the drain pan underneath the engine oil filter. Use a strap wrench or equivalent tool to loosen the oil filter (do not remove yet), allowing the oil to drain. Once drained, unscrew the filter completely by hand. Use a rag, if necessary, to keep from burning your fingers. When the filter comes loose from the engine, turn the mounting base upside down to avoid spilling the remaining oil.
- Wipe the engine filter mount clean with a rag. Coat the rubber gasket on the new oil filter with clean engine oil, applying it with a finger. Carefully start the filter onto the threaded mount. Turn the filter until it touches the engine mounting surface. Tighten the filter, by hand, an additional 1 / 2 turn or as recommended by the filter manufacturer.
- Lower the vehicle. Refill the crankcase with four quarts of engine oil. Replace the filler cap and start the engine. Allow the engine to idle, checking for any oil leaks. Shut off the engine, wait for at least five minutes, and check the oil level with the dipstick. Add oil if necessary.
Store the used oil in a suitable container made for that purpose, until you can find a service station or garage that will accept the used oil for recycling.
