The Perfect Balance: Red Line 5W40 Full Synthetic Motor Oil

Achieve superior engine protection and maximized power output across all driving conditions with Red Line 5W40 Synthetic Motor Oil (Part #15404), available now at Straight Six Imports. This popular viscosity is the ideal choice for modern European and high-output JDM turbocharged engines that demand a lubricant capable of handling both extreme cold starts and high operating temperatures.

Built on Red Line's premium Polyol Ester/PAO base stocks, the 5W40 formula maintains an incredibly stable oil film under high shear, preventing metal-to-metal contact where traditional oils break down.

Key Features for Performance and Forced Induction:

• Broad Compatibility: Excellent for modern European engines requiring ACEA C3 / A3/B4 specifications, and highly recommended for turbocharged platforms like the Subaru WRX STI, Mitsubishi Evolution, and performance Audi/VW/BMW models.

• High-Temperature Stability: The true synthetic ester base provides exceptional thermal stability and film strength, crucial for lubricating and cooling turbocharger bearings operating at extreme heat.

• Low-Temperature Flow: The 5W rating ensures rapid circulation during cold starts, minimizing wear before the engine reaches operating temperature—ideal for the Canadian climate.

• High ZDDP Content: Contains robust levels of Zinc and Phosphorus (ZDDP) anti-wear additives, providing vital protection for valvetrain components in high-revving and modified engines.

• Reduces Oil Consumption: Features extremely low volatility (NOACK), helping to minimize oil consumption and improve engine efficiency.

Choose the proven performance and protection of Red Line 5W40 Motor Oil (15404) for your turbocharged or highly tuned machine.
