The 2018 Honda Accord is part of Honda’s 10th-generation lineup, available with a 1.5L turbocharged engine and a 2.0L naturally aspirated engine. Both engines are designed for efficiency and performance, but they require the correct oil specification to maintain long-term reliability and fuel economy.
Using the right oil type is critical because Honda’s Earth Dreams engines rely on low-viscosity synthetic oil to reduce friction, protect turbo components (1.5T), and maintain smooth VTEC operation (2.0L).
2018 Honda Accord Oil Type
The recommended oil type for the 2018 Honda Accord is:
- SAE 0W-20 full synthetic oil (factory recommended for all trims)
- Must meet API SP / ILSAC GF-5 or GF-6 specification
Honda strongly recommends full synthetic 0W-20 oil for both the 1.5L turbo and 2.0L engine to ensure proper lubrication, fuel efficiency, and turbo protection.
Best Choice: SAE 0W-20 full synthetic oil for maximum efficiency and engine protection.
2018 Honda Accord Oil Capacity
Oil capacity varies depending on engine type and whether the oil filter is replaced.
