The Mobil 1 5W‑30 (5 L) is a full synthetic engine oil engineered to protect modern gasoline and light-duty diesel engines, including those with turbocharging, direct injection, or hybrid powertrains. Its “Triple Action Power” formula provides quick lubrication during cold starts, maintains robust oil film during high-temperature operation (up to 500 °F), and features powerful cleaning agents to prevent sludge and deposit buildup—helping engines stay clean and efficient throughout extended service intervals. This oil meets or exceeds the top industry standards (API SP, ILSAC GF‑6A) and holds OEM approvals such as GM dexos1 Gen3 and Honda/Acura’s HTO‑06, making it suitable for a wide range of vehicle makes and models.

In everyday use, drivers consistently report smoother engine operation, quieter performance, and improved fuel efficiency—with some noticing better mileage in spirited driving conditions or city traffic . Independent testing and manufacturer data show that this oil resists viscosity breakdown and maintains thermal stability up to 10,000 miles between oil changes, making it strong protection for both highway and severe driving conditions. Packaged in a convenient 5-liter volume, it’s an ideal choice for routine maintenance and long-term engine care.
