What kind of engine oil is suitable for the 1.6L New Focus?
1 Answers
Ford Focus 1.6L models require no more than 4.5L of engine oil. For the 1.6L model, you can use Ford's specialized engine oil, Shell Helix XH6, etc., with the corresponding oil specification being 5W30. Since the Focus 1.6L model uses a naturally aspirated engine, both mineral oil and synthetic oil are suitable for this engine. Below are the specific details about engine oil specifications: 1. API Grade: API stands for the American Petroleum Institute, and the API grade represents the quality level of engine oil. Codes are used to describe the working capability of engine oil. The grades are classified as SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN, with letters further in the alphabet indicating higher grades. SP is currently the highest grade of engine oil. SJ was the standard in the 1990s, SL in 2001, SM in 2004, and SN in 2010. 2. Engine Oil Grade: SP-grade oil, being the highest grade, generally falls under the category of fully synthetic oil in oil classification. Semi-synthetic oils are mainly SL and SM grades, with some being SN grade. Among international brands, most engine oils are SF grade or higher. For example, Shell Ultra Helix is API-SM grade, while Shell Red Helix engine oil is API-SG grade, indicating that the quality grade of Ultra Helix is higher than that of Red Helix.
