Most 2018 Audi models take synthetic engine oil that meets Volkswagen Group specifications, with 0W-20 being common for many gasoline engines. The exact viscosity and spec depend on the engine and model, so always check the owner's manual or the oil filler cap to confirm.
Overview of oil requirements
Understanding what oil your 2018 Audi needs starts with the VW Group standards. The required specification and viscosity vary by engine, so the precise answer for your car comes from the official documentation and the engine itself.
- Oil must be synthetic and meet Volkswagen Group specifications (for most gasoline engines, common specs include 502.00 and/or 504.00; for diesels, 507.00 may apply).
- Viscosities you might encounter include 0W-20, 0W-30, 5W-30, and 5W-40, depending on the engine and climate.
- The exact required spec and viscosity depend on the engine type, model (A4, A6, Q5, etc.), and even the VIN.
- Always verify the spec on the engine oil cap and in the owner's manual to avoid warranty issues.
Bottom line: the right oil is defined by the VW Group standard and the engine's viscosity requirement for your specific model.
How to confirm the right oil for your 2018 Audi
To ensure you use the correct oil for your exact vehicle configuration, follow these steps:
- Consult the owner's manual section on engine oil to note the required viscosity and specification.
- Check the oil fill cap on the engine for the listed specification.
- Identify your engine code or VIN and look up the precise spec in Audi’s official service resources or through your dealer.
- Choose a high-quality synthetic oil that meets the specified VW Group standard (for example, 0W-20 meeting 502.00/504.00, or 5W-40 meeting 504.00/507.00).
Using the exact oil specification helps ensure proper protection and preserves warranty coverage.
Engine-type specifics
Gasoline engines
Gasoline engines in many 2018 Audis typically use synthetic oil with a viscosity of 0W-20 or 0W-30, depending on the engine and climate. The most common setup for turbocharged four-cylinders and V6s is 0W-20 that meets VW 502.00 and/or 504.00; some variants may require 5W-30 or 5W-40. Always confirm with the exact model.
- Example: 2.0L TFSI variants often use 0W-20; some markets or engines may specify 5W-30.
- The oil cap and manual will state the precise spec for your engine.
In short, 0W-20 is the typical default for many 2018 Audis’ gasoline engines, but verification is essential.
Diesel engines
Diesel engines offered in 2018 Audis generally require synthetic oil meeting VW 507.00, with viscosities around 5W-40. Some smaller diesels or different markets may specify 0W-40 or 5W-30; confirm your exact spec via the manual or dealer.
- Diesel with a diesel particulate filter (DPF) commonly uses 5W-40 under 507.00.
- Always verify the precise spec for your engine.
Diesel oil requirements differ from gasoline; always confirm the exact spec for your model.
Important notes
Using oil that does not meet the specified VW Group standard can affect engine performance and warranty. Rely on the exact spec from the owner's manual, the oil cap, or Audi’s official service resources, and consult a dealer if you’re unsure.
Summary
For a 2018 Audi, the safe general guideline is to use a high-quality synthetic oil that meets Volkswagen Group specifications, with 0W-20 being common for many gasoline engines. The exact viscosity and specification vary by model and engine, so always verify with the owner's manual or the oil cap, and consult a dealer if in doubt.
What oil does a 2018 Audi take?
Engine Oil
Viscosity: 5W-40 (All TEMPS) - If synthetic oil that meets the applicable Audi, Volkswagen oil quality standard with the recommended viscosity grade is not available in your area, be sure to use a viscosity grade suitable for the climate, season, and operating conditions that exist where the vehicle is used.
Can I use 5W-30 in my Audi?
Oil Viscosity Recommendations
SAE 5W-30: Ideal for a wide range of temperatures and common for most Audi engines. SAE 5W-40: Provides additional protection in warmer climates or for turbocharged engines. SAE 0W-30: Suitable for cold weather and newer Audi models with advanced engines.
Does Audi need full synthetic oil?
Audi recommends full synthetic oil for most models because it handles heat better and lasts longer. Depending on how you drive, the interval can range from every five thousand to ten thousand miles. Checking your owner's manual is always the best guide for the right type and schedule.
