VW 507.00 Specification Explained
The VW 507.00 oil specification is mandatory for Audi A3 TDI engines equipped with Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) systems This low-ash (low SAPS) formulation is designed to:
Protect the Diesel Particulate Filter from ash accumulation
Enable extended drain intervals of 10,000 miles or once yearly
Maintain compatibility with modern emission control systems
Provide optimal fuel economy and reduced emissions
Important: VW 507.00 can be used in place of VW 505.01 specification, but should not be used in the 2004 VW BKW V10 TDI engines For first-generation A3 TDI (1996-2003) without DPF, VW 505.00 specification applies

Oils to Avoid in Audi A3 Diesel
Using incorrect oil can seriously damage your TDI engine and DPF system:
Do Not Use:
Conventional (non-synthetic) motor oils
Oils lacking VW 507.00 certification (for 2003+ models with DPF)
High-ash oils not designed for DPF systems
VW 509.00 specification oils (not backward compatible with older TDIs)
Universal "one-size-fits-all" diesel oils
Why Specification Matters: Non-compliant oils produce ash that clogs the DPF, leading to frequent regeneration cycles, reduced fuel economy, DPF warning lights, and potentially complete DPF failure requiring expensive replacement ($1,500-$4,000) Using incorrect oil also voids Audi warranty coverage.
For proper oil checking technique, see our guide on checking oil hot or cold.
How to Verify Oil Specification
Before purchasing any oil for your A3 TDI, verify specification compliance:
Check the bottle label - Look for "VW 507.00" or "507 00" printed clearly
Visit manufacturer websites - Mobil, Castrol, and Liqui Moly have online oil finders
Consult NHTSA TSB - Technical Service Bulletin 17 lists oils meeting Audi quality standards
Use Liqui Moly Oil Guide - The brand offers a comprehensive online tool
Check owner's manual - Confirm the required specification for your specific engine year

Frequently Asked Questions
What oil does Audi recommend for A3 TDI?
For modern A3 TDI engines (2003 and newer) with DPF systems, Audi requires VW 507.00 specification oil in SAE 5W-30 or 0W-30 viscosity The official TDI spec oil from VW/Audi is now Mobil 1 ESP 0W-30 First-generation A3 TDI (1996-2003) without DPF requires VW 505.00 specification
Can I use 5W-40 oil in my Audi A3 diesel?
For A3 TDI engines with DPF (2003+), 5W-30 meeting VW 507.00 is required Using 5W-40 may be acceptable for older 1.9L TDI engines (1996-2003) if it meets VW 505.00 specification. However, modern TDI engines specifically require the low-ash 507.00 formulation that is typically available only in 5W-30 or 0W-30.
How often should I change oil in my Audi A3 TDI?
VW 507.00 oils are designed for extended drain intervals of 10,000 miles or once yearly, whichever comes first Severe driving conditions (frequent short trips, dusty environments, towing) may require more frequent changes. Many owners prefer 7,500-10,000 mile intervals to balance protection and economy.
Is Liqui Moly better than Castrol for Audi A3 diesel?
Both brands meet VW 507.00 specifications and provide excellent protection Forum discussions indicate some owners experience lower oil consumption with Liqui Moly products Castrol is often preferred by dealers due to OEM supplier relationships. Both are solid choices—personal preference and availability typically determine the better option.
What happens if I use non-VW 507.00 oil in my A3 TDI?
Using non-compliant oil in DPF-equipped TDI engines produces excess ash that accumulates in the Diesel Particulate Filter This causes increased regeneration cycles, reduced fuel economy, DPF warning lights, and potentially complete DPF failure requiring expensive replacement. Non-compliant oil also voids warranty coverage.
