What Engine Oil Should I Use?


What is the best type of engine oil for my 2005 Honda Civic? It says 20/50, but should it be regular oil, synthetic, or semi-synthetic?

Thank you

What Engine Oil Should I Use?

The Manufacturers recommended engine oil is SAE 0W-20. However the manufacturer notes: API – SAE 5W-20 oil may be used if SAE 0W-20 is not available. Excluding the oil left remaining in the engine. You may use a synthetic motor oil if it displays the API Certification Seal, and it is the proper weight. I did look up and found a great deal on SAE0-20 Oil.

Caution: Prolonged and repeated contact with engine oil and grease will result in removal of natural oils from skin, leading to dryness, irritation and dermatitis. In addition, used engine oil and grease contains potentially harmful contaminants which may cause skin cancer. Precautions should be taken when replacing lubricants to minimize risk of your skin making contact. Protective clothing and gloves that cannot be penetrated by oil should be worn. The skin should be washed with soap and water or waterless hand cleaner to remove any used engine oil thoroughly. Do not use gasoline, thinners, or solvents.
In order to preserve the environment, used oil and used oil filters must be disposed of at designated disposal sites in accordance with EPA and local regulations.
