The best engine oil for an Audi A3 diesel is Mobil 1 ESP 0W-30, which carries the official VW 504 00/507 00 approval that every DPF-equipped A3 TDI requires. Liqui Moly Top Tec 4200 5W-30 offers the same approval at a lower price. Whichever you choose, confirm VW 507 00 on the maker’s data sheet first — the wrong oil slowly clogs the particulate filter.
Key takeaways:
- Every DPF-equipped A3 TDI (roughly 2006 onward) requires VW 507 00 low-SAPS oil.
- All 7 oils below hold a genuine VW 504 00/507 00 approval, checked against maker data sheets.
- Two oils often recommended in forums do NOT qualify: Total INEO MC3 and Pentosin Pento High Performance.
- A VW 507 00 oil is backward-compatible with most older VW diesel specs.
- Trust the approval printed in the maker’s data sheet, not the storefront listing.
What oil does an Audi A3 diesel actually require?
An Audi A3 TDI with a diesel particulate filter requires oil approved to VW 507 00 — a low-SAPS (low sulphated ash, phosphorus and sulfur) specification designed to keep the DPF from clogging with ash. This is not a viscosity question but an approval question: a 5W-30 without VW 507 00 can be worse for the engine than a 0W-30 with it.
VW 507 00 explained
VW 507 00 limits the ash-forming additives in the oil. When trace amounts of oil burn in a diesel combustion chamber, high-ash formulas leave residue the DPF cannot regenerate away; over tens of thousands of miles that residue permanently fills the filter. The spec also qualifies the oil for VW’s LongLife variable service intervals. VW 504 00 is the paired gasoline-engine spec, which is why approved products list both — service literature filed with NHTSA shows how strictly VW group ties TDI service to these specs.
Specs by generation
The second-generation A3 (8P) brought the TDI to the US for 2010–2013 with the 2.0 CBEA/CJAA engines — all DPF-equipped, all 507 00. The third generation (8V) sold the 2.0 TDI (CRUA) for 2015–2016, also 507 00. Early European 8P diesels without a DPF (some 1.9 TDI versions) could run VW 505 01 oil, but if your A3 has a particulate filter — every US car does — 507 00 is the requirement.
Oil capacity
Capacity depends on the engine, not the model year alone. The 2015–2016 A3 2.0 TDI (CRUA) takes about 5.5 liters (5.8 US quarts) with a filter change, a figure that AMSOIL’s lookup and Blauparts’ service guide both list. Published figures for the 2010–2013 cars vary between sources, so confirm the exact capacity for your engine code in the owner’s manual before buying — one 5-liter jug is not always enough.
Note (Autvex): Oil specs and approvals current as of July 2026. Makers occasionally reformulate; the data sheet on the maker’s own site is always the final word.
The 7 best engine oils for Audi A3 diesel — all VW 507 00 approved
Every product below holds a genuine VW 504 00/507 00 approval, which we verified against each maker’s data sheet rather than store listings. The differences between them are price, cold-flow behavior and availability — not compliance.
#1. Mobil 1 ESP 0W-30 — best overall
Per the Mobil 1 ESP 0W-30 data sheet, this oil is approved for VW 504 00/507 00 plus MB 229.31/229.51/229.52 and Porsche C30. The 0W rating gives it the strongest cold-start flow of the group, useful for short-trip driving where the engine spends more time below operating temperature. It is also the easiest 507 00 oil to find on US shelves. Caveat: it usually costs more per quart than the value picks below.
#2. Liqui Moly Top Tec 4200 5W-30 — best value
The Top Tec 4200 New Generation carries VW 504 00/507 00, ACEA C3 and a long list of other approvals. German TDI specialists have used it as a house oil for years, and per-liter pricing in 5-liter jugs is regularly the lowest of any approved product. Caveat: stock fluctuates at general parts stores, so it is often an online purchase.
#3. Castrol EDGE Professional Longlife III 5W-30 — the dealer match
Castrol’s product data sheet lists VW 504 00/507 00 and Porsche C30 for this oil, and it is the same family VW group dealers have filled at service counters for years. Choose it if you want the “what the dealer would use” answer with no further thought. Caveat: the Professional line is distributed through workshops, so retail availability is inconsistent.
#4. Ravenol VMP 5W-30 — enthusiast pick
Ravenol VMP 5W-30 is approved for VW 504 00/507 00 with MB 229.51 and BMW Longlife-04 alongside. The German maker has a strong following among TDI owners who track oil analysis results. Caveat: in the US it is a specialist-shop and online product, rarely on a local shelf.
#5. Motul Specific 504 00 507 00 5W-30
The approval is in the name: Motul builds this oil specifically to the VW 504 00/507 00 sheet, as its product data sheet confirms. It suits owners already loyal to Motul from motorcycles or motorsport. Caveat: it trades at a premium close to Mobil 1 ESP without being easier to find.
#6. Total Quartz INEO Long Life 5W-30 — check the label carefully
TotalEnergies’ US catalog lists Quartz INEO Long Life 5W-30 with VW 504 00/507 00, BMW LL-04 and MB 229.51. It is a solid, often well-priced choice — but Total also sells the near-identically named Quartz INEO MC3 5W-30, which is only a VW 505.01-level oil. Grab the wrong jug and you lose DPF protection; the “Long Life” wording on the label is the part that matters.
#7. Pentosin Pento Super Performance III 5W-30 — check this label too
Pentosin’s data (distributed by CRP Automotive in the US) shows Pento Super Performance III 5W-30 approved for VW 504 00/507 00 with backward compatibility to the older 502 00/505 00 family. The trap mirrors Total’s: Pentosin’s Pento High Performance 5W-30 covers only VW 502 00/505 01 and is not a DPF oil, despite the confident name.

Oils people recommend that are NOT VW 507 00
Forum threads and even some shop blogs regularly suggest two oils for the A3 TDI that fail the spec — both from reputable brands, which is exactly why the mistake spreads.
Total Quartz INEO MC3 5W-30
Per TotalEnergies’ own catalog, MC3 is positioned for VW 505.01-type applications — and that is a maker recommendation, not a VW approval. It is a fine oil for the engines it targets; an A3 TDI with a DPF is not one of them.
Pentosin Pento High Performance 5W-30
CRP’s data sheet lists VW 502 00/505 01 — specs for older, non-DPF applications. The name sounds premium, and the bottle sits next to the correct Super Performance III on the same shelves.
Why a 505.01 oil hurts a DPF engine
Oils built to older specs carry more ash-forming additives. The engine runs fine, which is what makes the mistake invisible: the damage accumulates in the particulate filter over tens of thousands of miles, until regeneration cycles shorten and a four-figure DPF replacement appears on an estimate. Spec compliance is cheap insurance against an expensive, slow failure.
How to verify an approval yourself
Read the label’s exact wording first: “VW 504 00/507 00” listed under approvals means the maker holds the certificate, while phrases like “meets the requirements of” or “recommended for” mean it does not. Then confirm on the maker’s product data sheet — every brand above publishes one — rather than a marketplace listing, which sellers frequently copy incorrectly. Two minutes of checking protects a filter that costs four figures to replace; we keep broader Audi maintenance guides in our Audi section.
Which oil should you pick?
Match the oil to your situation rather than the brand’s marketing. Cold climate or mostly short trips: the 0W-30 Mobil 1 ESP flows fastest at start-up. Tightest budget without compromise: Liqui Moly Top Tec 4200 in the 5-liter jug. Want exactly what a dealer would install: Castrol EDGE Professional Longlife III. Ordering online anyway and enjoy the enthusiast route: Ravenol VMP. If you also run an A4 TDI, the logic is identical — our guide to the best engine oil for Audi A4 diesel walks the same specs — and whichever you choose, know when to check your oil level so top-ups use the same approved oil.
Expert view (Autvex): Compliance first, brand second. All seven oils protect the DPF equally on paper; extra money buys availability and cold-start behavior, not “more approval.” The real risk isn’t picking the wrong brand from this list — it’s grabbing a near-identically named jug that was never 507 00 at all.
Frequently asked questions about oil for the Audi A3 diesel
What oil does Audi recommend for the A3 TDI?
Audi requires oil approved to VW 507 00 for every A3 TDI with a diesel particulate filter — which includes all US-market cars (2010–2013 and 2015–2016). Viscosity is typically 5W-30 or 0W-30; the approval matters more than the viscosity number. Mobil 1 ESP 0W-30 and Liqui Moly Top Tec 4200 5W-30 both hold that approval.
Can I use 5W-40 oil in my Audi A3 diesel?
Not in a DPF-equipped car. Common 5W-40s carry VW 502 00/505 00-era approvals with higher ash content, and none of the mainstream 5W-40s hold VW 507 00. Using one won’t cause immediate symptoms, but it loads the particulate filter with ash it cannot burn off. Stay with a 507 00-approved 5W-30 or 0W-30.
How often should I change the oil in an A3 TDI?
Under VW’s LongLife regime, a 507 00 oil supports variable intervals of up to roughly 2 years or 18,600 miles (30,000 km) in European service schedules; US owners commonly change at 10,000 miles or once a year, whichever comes first. Short-trip city driving justifies the shorter end. The interval assumes an approved oil — a non-507 00 oil voids the long-interval logic entirely.
What happens if I use non-VW 507 00 oil in my A3 TDI?
Nothing you can feel at first, which is the danger. Higher-ash oil gradually loads the DPF with residue that regeneration cannot remove, shortening regeneration cycles and eventually requiring filter cleaning or replacement — commonly a four-figure job. If it happened once, change back to a 507 00 oil at the next service; a single fill rarely causes lasting harm.
Is Liqui Moly better than Castrol for an A3 diesel?
For spec compliance they are equals: Top Tec 4200 5W-30 and EDGE Professional Longlife III 5W-30 both hold VW 504 00/507 00. Liqui Moly usually wins on retail price per liter; Castrol matches what dealers install. Choose by price and availability — the engine cannot tell the difference between two oils holding the same approval.
How do I verify an oil really has VW 507 00 approval?
Check the maker’s product data sheet on its own website and look for “VW 504 00/507 00” under approvals — wording like “meets” or “recommended for” is not an approval. Ignore marketplace listings, which often copy specs incorrectly. Every oil in this guide was verified this way against Mobil, Liqui Moly, Ravenol, Castrol, Motul, TotalEnergies and Pentosin data.
