How Much Oil a 2008 Audi 2.0T Takes

A 2008 Audi 2.0T engine typically takes about 4.3–4.6 liters (4.5–4.9 US quarts) of engine oil with a filter change, depending on the specific engine code and model (A4, A3, TT, etc.). This article explains the exact oil capacities, how to confirm them for your car, and what type of oil you should use.

Understanding the 2008 Audi 2.0T Engine Variants

The 2008 model year includes several Audi vehicles fitted with a 2.0-liter turbocharged (2.0T) four-cylinder engine. While they are all 2.0T engines, there are small differences across models and engine codes that slightly affect oil capacity and specifications.

Common 2008 Audi Models With 2.0T Engines

The following models are among the most common in 2008 to feature the 2.0T engine, and most share very similar oil capacity requirements.

These models all use a version of the 2.0-liter turbocharged inline-four, and knowing your exact model helps you match the correct oil capacity and spec.

• 2008 Audi A4 2.0T (B7 generation, sedan/Avant)
• 2008 Audi A3 2.0T
• 2008 Audi TT 2.0T
• Some markets: 2008 Passat/other VW platform cars with similar 2.0T FSI/TSI engines (though technically Volkswagen-badged)

While these engines are closely related, small differences in oil pan design, filter housing, and engine code can shift the total fill by a few tenths of a liter, which is why verifying the exact engine code is important.

Typical Oil Capacity for the 2008 Audi 2.0T

For most 2008 Audi 2.0T engines, the manufacturer-stated oil capacity with a filter change is in the mid‑4‑liter range. In US measurements, this works out to just under 5 quarts.

Approximate Oil Capacity Range

The following range reflects what owners, service manuals, and dealer data commonly report for 2008 2.0T engines.

This list summarizes the typical oil-fill amounts you can expect when changing oil and filter on a 2008 Audi 2.0T.

• With filter change: about 4.3–4.6 liters (roughly 4.5–4.9 US quarts)
• Without filter change: typically around 0.2–0.3 liters (0.2–0.3 quarts) less
• Common “safe” fill amount: start with about 4.0 liters (4.2 quarts), then top up as needed based on dipstick reading

These numbers provide a practical working range: you should plan to have at least 5 US quarts of oil on hand, even though you are unlikely to use the full amount.

Engine Codes and Small Capacity Differences

Most 2008 2.0T Audis use the EA113-series 2.0 FSI turbo engines (for example, engine code BPJ, BPG, BWT, depending on market). Oil capacity spec is usually listed in the owner’s manual and workshop data as roughly mid‑4 liters.

To verify your exact capacity:

Follow these steps to locate the correct capacity for your specific car, using Audi’s official documentation and identification labels.

1. Check the owner’s manual: Look for the “Engine oil capacity” section under maintenance specifications.
2. Read the trunk or service-book label: On many Audis, the engine code appears on a data sticker in the spare-tire well or service booklet.
3. Use the VIN at a dealer or parts counter: A dealer can pull the exact engine code and capacity from Audi’s system using your VIN.
4. Consult a factory workshop manual: Online databases and OEM service info will list exact capacity by engine code.

Identifying the engine code is the best way to be precise, but even without it, staying within the 4.3–4.6 liter range and confirming by dipstick is reliable in practice.

Recommended Oil Type and Specification

Matching the right quantity is only part of the job; using the correct oil specification is just as critical for engine longevity, turbo health, and warranty or goodwill coverage from Audi.

Viscosity Grade

For most climates and normal driving, Audi typically recommends the following viscosity for 2008 2.0T engines:

This list outlines the most commonly approved viscosity grades suitable for a 2008 Audi 2.0T, according to typical Audi guidance.

• 5W-40 fully synthetic (very common choice in many markets)
• 5W-30 fully synthetic (when it meets the right VW spec)
• In very cold climates: 0W-30 or 0W-40 may be used if they meet the correct VW standard

The exact viscosity Audi lists can vary by market and climate, but most owners in temperate to warm climates successfully use a high-quality 5W-40 that meets Audi/VW specs.

Volkswagen / Audi Oil Specifications

More important than viscosity alone is the official oil specification. For a 2008 Audi 2.0T, you should use oil that meets one of the following VW standards (check your manual for the exact one):

These specifications ensure the oil is tested and approved for the high-heat, direct-injection, turbocharged environment of the 2.0T engine.

• VW 502 00 – Common spec for gasoline engines of this era, including the 2.0T.
• VW 504 00 – Long-life oil spec (often used with flexible/extended service intervals in some regions).

When shopping, look on the bottle for wording like “Meets or exceeds VW 502 00 (or 504 00).” Major brands (Castrol, Mobil 1, Liqui Moly, Motul, etc.) make oils that carry this approval.

How to Correctly Fill the Oil in a 2008 Audi 2.0T

Even with the right capacity figure, the safest approach is to fill slightly short of the maximum, then top off while checking the dipstick. This accounts for minor differences between engines and any oil remaining in the system.

Step-by-Step Filling Approach

The following steps outline a practical way to refill engine oil in a 2008 Audi 2.0T to avoid overfilling while ensuring proper lubrication.

1. Drain the oil completely: Warm the engine briefly, then drain the oil from the sump and remove the old filter.
2. Install a new oil filter: Fit the new filter and ensure the sealing surfaces are clean and the O-ring is lubricated with fresh oil.
3. Add an initial amount: Pour in about 4.0 liters (approx. 4.2 quarts) of fresh oil.
4. Check the dipstick: Wait a minute for oil to settle, then check the dipstick. It should usually read between the low and mid mark at this stage.
5. Top up gradually: Add oil in small increments (100–200 ml / 3–7 oz) until the level is just below or at the top mark on the dipstick.
6. Run the engine: Start the engine for 30–60 seconds, shut it off, wait a few minutes, then recheck the dipstick and adjust if necessary.

This method keeps you clear of overfilling—which can cause foaming and catalytic converter or PCV issues—while ensuring the engine has the full required amount of oil.

Signs You Might Have the Wrong Oil Level

After an oil change, watching for early warning signs can prevent minor mistakes from turning into expensive repairs.

Indicators of Overfilling or Underfilling

The following symptoms can hint that your 2.0T’s oil level is not within the recommended range.

• Too low: Oil warning light flickering, ticking noise from valve train, or louder engine at startup.
• Too high: Oil smell, smoke from exhaust, rough idle, or oil seepage around seals/PCV system.
• General check: If the dipstick level is below the minimum or significantly above the maximum mark, the level is incorrect.

If you suspect a serious overfill, it is safer to drain and refill to a known good amount, then recheck, rather than attempt to drive long distances with an incorrect oil level.

Why Accurate Oil Fill Matters for the 2.0T

The 2.0T FSI engines from this period have a reputation for being sensitive to maintenance quality. Oil level and oil quality are central to avoiding some well-known issues.

Engine Longevity and Common Issues

The oil system in a turbocharged direct-injection engine is under heavy stress, and proper filling plays a major role in mitigating that.

These points summarize the key reasons why maintaining correct oil level and specification is especially important in a 2008 Audi 2.0T.

• Turbocharger health: The turbo relies on clean, high-quality oil for lubrication and cooling; low oil level can cause rapid damage.
• Sludge and deposits control: Correct spec oil and timely changes help reduce sludge and varnish that can block tiny oil passages.
• PCV and catalytic converter protection: Overfilling can increase oil blow-by into the intake and exhaust systems, shortening component life.
• Maintaining oil pressure: Too little oil can result in loss of oil pressure during hard acceleration or cornering.

Consistently using the right oil type, spec, and volume will not only keep the engine running smoothly but also reduce the likelihood of expensive repairs down the line.

Summary

A 2008 Audi 2.0T engine generally takes around 4.3–4.6 liters (4.5–4.9 US quarts) of fully synthetic oil with a filter change. The exact figure can vary by model and engine code, so the best practice is to start with about 4.0 liters and use the dipstick to top off gradually. Always use oil that meets VW 502 00 or 504 00 specifications, commonly in 5W-40 or approved 5W-30 viscosity. Verifying capacity in your owner’s manual and filling carefully ensures the turbocharged 2.0T engine remains well-protected and reliable over time.
