Can I switch motor oil brands?
2 Answers
Motor oil brands can be switched. Here are precautions when changing to other brands: 1. Most importantly, purchase oil through official channels: Never use unverified small-brand oils, as poor-quality oil may cause engine damage. 2. For older vehicles with significant sludge buildup, it's best to clean the sludge thoroughly before changing oil, which not only ensures better lubrication but also helps restore engine performance. 3. Always thoroughly clean the old oil: First drain the old oil as completely as possible, then add a small amount of new oil or specialized engine cleaning oil for flushing.
Of course you can switch motor oil brands. I've changed brands three or four times in over a decade of driving. The key is checking certification standards - if your factory oil was SN grade 5W-30, the new oil must meet the same specification. Some car owners worry about mixing issues, but simply draining the old oil completely solves this. However, avoid frequent brand switching as engines need time to adapt to new formulations. I recommend first checking your owner's manual, then comparing parameters of major brands like Shell and Mobil online. Last month I switched my Japanese car to German-spec oil - cold start noise reduced noticeably though fuel consumption increased slightly.
