276DT Oil Capacity, Grade & Service Data

Reference figures for the 2.7‑litre V6 diesel (AJD‑V6), fitted across XF, XJ and shared with Land Rover. No opinions, no verdicts - just the numbers, correctly sourced and verified against Jaguar variant differences.

The 276DT takes approximately 6.5 litres with filter change [PATTERN DATA], to Jaguar low‑SAPS specification, typically 5W‑30.

Full specification table, variant differences, common mistakes, and the oil‑pump caveat explained below.

Variant Differences

The 276DT is fitted across several Jaguar models. While the core specification is consistent, sump capacity and filter access vary slightly by application. The engine is also shared with Land Rover (e.g., Discovery 3, Range Rover Sport), but Jaguar‑specific fitment is listed below.

ApplicationCapacity NoteFilter Access
XF (X250) 2.7DStandard 6.5L figure appliesTop‑mounted, accessible from above
XJ (X350 / X351) 2.7DStandard figure, some early builds noted slightly higher sump capacityTop‑mounted
S‑Type 2.7DStandard figure appliesTop‑mounted, tighter access on early models

For the later 306DT (3.0‑litre V6), the capacity and grade are similar but not identical; always confirm via your VIN - see our engine code decoder for help. The 276DT is also used in Land Rover vehicles; those applications may have different oil specifications due to different sump designs and service schedules – check your specific vehicle handbook.

Year, Market & Facelift Variations

The 276DT (AJD‑V6) was introduced in 2004 in the S‑Type and later spread to the XF (X250) and XJ (X350/X351). Early UK‑spec cars (2004–2009) are more prone to oil pump housing failure, which is often exacerbated by oil degradation. In 2009, Jaguar revised the oil pump design and updated the ECU software to improve oil pressure management. From 2010, a revised oil specification (STJLR.03.5006) was introduced, which is backward‑compatible but requires the correct low‑SAPS approval.

For UK market cars, the VIN’s 10th character indicates the model year - see our engine code guide for decoding. If your car was built before 2009 and you experience low oil pressure warnings, it is worth checking with a Jaguar specialist whether the updated oil pump has been fitted.

Real‑World Caveats

The manufacturer's 16,000‑mile interval assumes motorway‑weighted use. In real UK conditions, short urban journeys can lead to fuel dilution and oil degradation, which is particularly dangerous on the 276DT because the oil pump housing has a known weakness. Failure of the oil pump can result in catastrophic engine damage – see our 276DT oil pump failure page for a full explanation.

Independent specialists we've spoken to frequently recommend a shorter, 8,000‑mile interval for owners whose driving is predominantly short urban trips, regardless of what the service computer indicates. This is not manufacturer guidance - it is a practical adjustment specialists make based on what they see coming through the workshop. The cost of an extra oil change is a fraction of the alternative, which is a seized engine due to oil starvation.

Additionally, using the correct low‑SAPS oil is critical - see the Common Mistakes section below for why.

Common Mistakes

How to Verify on the Actual Vehicle

The dipstick and filler cap on the 276DT are both clearly marked and accessible from above without removing any panels. To confirm your exact build spec:

  1. Check the engine number stamped on the cylinder block - the location is described on our Engine Number Location guide.
  2. Use the VIN to decode the exact engine variant and year - our VIN decoder can help.
  3. Consult the service book or the vehicle’s infotainment system for the service history; the oil change interval may have been modified by previous owners.
  4. If in doubt, a Jaguar specialist can use the manufacturer’s diagnostic tool to read the exact oil specification stored in the ECU.

Early and late production runs occasionally carry minor running changes that aren't always reflected in aftermarket reference sources - the VIN is your best guide.
