Frequently Asked Questions for US A3 Diesel Owners

What oil specification is required for my Audi A3 2.0 TDI in the US?

Your A3 2.0 TDI requires oil meeting VW 507.00 specification for optimal DPF protection and extended 10,000-15,000 mile service intervals^[3]. ACEA C3 oils provide acceptable alternative protection but may require shorter change intervals. Never use conventional oils not meeting these specifications.

Can I use regular 5W-30 motor oil in my Audi A3 diesel?

Regular 5W-30 motor oil without VW 507.00 or ACEA C3 specifications will damage your DPF system and void your warranty. A3 TDI engines require low-SAPS (sulfated ash, phosphorus, sulfur) formulations specifically designed for modern diesel emissions systems^[4].

How often should I change oil in my A3 TDI with synthetic oil?

Using authentic VW 507.00 synthetic oils allows 10,000-15,000 mile service intervals as designed by Audi. However, severe US driving conditions (stop-and-go traffic, extreme temperatures, short trips) may require 7,500-10,000 mile intervals for optimal protection^[5].

What’s the oil capacity for Audi A3 diesel engines?

The 2.0 TDI engine requires 4.9 quarts including the oil filter, while the 1.6 TDI needs 4.3 quarts with filter^[6]. Always verify the exact amount in your owner’s manual, as capacity may vary slightly between model years and engine variants.

Where can I buy VW 507.00 approved oil in the United States?

VW 507.00 approved oils are available through Audi dealerships, European auto parts specialists, and online retailers. Major brands like Castrol EDGE Professional, Mobil 1 ESP, and Liqui Moly Top Tec are readily available. Avoid generic oils claiming compliance without official approval documentation^[7].
