Frequently Asked Questions for US A4 Diesel Owners

What oil specification is required for my Audi A4 2.0 TDI in the US?

Your A4 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 shortened change intervals. Never use conventional oils or formulations lacking proper diesel particulate filter protection.

Can I use regular automotive oil in my Audi A4 diesel engine?

Regular automotive oils without VW 507.00 or ACEA C3 specifications will damage your expensive DPF system and void your warranty. A4 TDI engines require low-SAPS (sulfated ash, phosphorus, sulfur) formulations specifically engineered for modern diesel emission systems and particulate filter protection^[4].

How often should I change oil in my A4 TDI with premium synthetic oil?

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

What is the oil capacity for my Audi A4 diesel engine?

All A4 2.0 TDI engines (2009-2015 model years) require exactly 5.0 quarts including the oil filter replacement^[6]. Always verify the precise amount in your specific model year owner’s manual, as capacity may vary slightly between production years and specific engine variants or optional equipment.

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

VW 507.00 approved oils are readily available through Audi dealerships, European automotive specialists, major auto parts chains (AutoZone, Advance Auto Parts), and online retailers (Amazon, RockAuto)^[7]. Major brands including Castrol EDGE Professional, Mobil 1 ESP, and Liqui Moly Top Tec maintain wide US distribution. Always verify authentic approval documentation to avoid counterfeit products.
