Should the 2019 Buick Excelle use 5W30 or 0W20?
1 Answers
The original engine oil for the Buick Excelle 1.4T is Mobil 1 5W-30 full synthetic oil; the Buick Excelle 1.5L uses the factory 5W-30 semi-synthetic oil. Below is the relevant introduction about engine oil: 1. Comparison between 5W30 and 0W20: 5W30 and 0W20 have different high and low-temperature performance. 0W20 has better low-temperature fluidity and can be used in lower environmental temperatures; while 5W30 has better high-temperature protection performance, with higher viscosity. Although it increases fuel consumption, considering the Excelle model, 5W30 is more suitable for its engine requirements. 2. Engine oil brands: For the choice of engine oil brands, if long-lasting oil is needed, Mobil oil can be used; if the oil needs strong cleaning ability, Shell oil is recommended; if the oil needs strong oil film toughness, Castrol is suggested. For turbocharged engines, which are prone to carbon deposits during high-speed operation, Shell oil with strong cleaning ability can be used.
