• Oil & Fluid Recommendations:
  • -Oil = 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-multigrage 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.
  • - Transmission Oils = Replace with 80w90 weight oil.

• Fuel Injection to Carburetor

• Tailpipe Installation:

  Tailpipe installation is beyond easy! We recommend using new tail pipe clamp kits whenever replacing or adding tailpipes to a new muffler. Tailpipes and installation clamps are each sold separately.
