Oil & Fluid Tech Tips

• Oil & Fluid Recommendations:
  • Engine Oil:

    Important Note: First and foremost, make sure that the engine oil you use has Zinc or, use a Zinc additive. Modern oils do not have Zinc which is required for older, solid lifter engines.

    • Straight 30 weight (SAE30 or HD30) is recommended for colder climates.
    • Straight 40 weight (SAE40 or HD40) is recommended for warmer climates.
    • 20W50 can be used in a pinch but we recommend non-multigrade oil.
    • We do not recommend using synthetic oils in air-cooled VWs. Synthetic oils are composed of thinner molecules, and in our experience tend to leak more frequently.

  • Brakes Fluid: We recommend DOT 3 Brake Fluid. DO NOT USE DOT 5.
  • Manual Transmission Oils: Replace with 80w90 weight oil.
  • Autostick Transmission Oils: 3 Quarts SAE 90 Gear Oil at Transmission, & 5.25 Quarts ATF Type A (Dexron III) Oil at Torque Converter & Oil Tank.
