How to Mix Synthetic & Traditional Oils
- 1). Choose a new mineral or synthetic oil. Synthetic oils are expensive but improve engine function in high performance cars and tend to fare better in cold climates. Car manufacturers should have information about which oils will lead to maximum performance in specific models.
- 2). Park the car on a flat surface. Let the engine cool by turning the car off for at least 1 hour.
- 3). Open the hood of the car.
- 4). Remove the dipstick, the long piece of metal attached to a handle. The dipstick should be located near the center or on the left side of the engine. If the dipstick is difficult to locate, consult the car manual.
- 5). Wipe off the dipstick with a rag. Re-insert the dipstick into the oil tank. Remove the dipstick from the oil tank.
- 6). Read the dipstick. The oil on the dipstick should be transparent, and it should reach the "full" line marked on the dipstick. If the oil is below the "full" line, add more oil to the engine.
- 7). Add a small amount of the new variety of oil to your engine. Reinsert the dipstick. If the oil has not yet reached the "full" mark, continue adding oil. When the dipstick reaches the "full" mark, oil mixing is complete.
