Fluids, capacities & service intervals
Assume nothing was done early: the factory schedule is long (12 months / 12,000 miles in the US), the full service manual isn't sold to owners, and only dealers can reset the service counter. Baseline every fluid once, keep receipts with OEM-spec fluids to protect the 5-year warranty, and note that much of the drivetrain is shared with BMW (B58/B57 engines, ZF 8-speed), so FCP Euro and other BMW specialists carry many of the consumables. On a Quartermaster that has worked hard (towing, a camper or tray load), treat it as arduous use and shorten every interval.
| ITEM | SPEC / CAPACITY | INTERVAL | NOTES & PARTS |
|---|---|---|---|
| Engine oil & filter | B58 petrol: 0W-20, ACEA C2 (dealers also cite C5 / API SP), BMW Longlife-17 FE+ · 6.5 L per the manual as quoted by owners; buy 7 L. B57 diesel: 0W-30 (the diesel manual lists Petronas Syntium 7000 E 0W-30) · capacity confirm in manual | Factory 12 months / 12,000 mi (US); owners and some dealers recommend 5,000–6,000 mi, or 6,000 mi for heavy use | Hood in maintenance position, engine cover off. 32 mm socket on the canister cap on top of the engine, 17 mm drain plug with a new copper washer, 25 Nm. Owners report the BMW B58 filter fits. Check the level in the menu, not by dipstick.BMW 0W-20 LL-17FE+ oil change kit for the B58 (7 L Genuine BMW oil + filter, O-ring, drain washer) · FCP Euro ↗ |
| Engine air filter | Panel filter with white felt pre-filter (glued on some, clipped into the box on others) | Every 2 years / 24,000 mi; much sooner after dusty trails | Captive PZ3 screws on the airbox. If the history is unknown, just replace it, because it's cheap.Mahle LX3985/1 air filter (owner-reported OEM match; not officially confirmed) · Amazon (search) ↗Mahle LX3985 BMW air filter (close sibling of LX3985/1; check it matches before buying) · FCP Euro ↗ |

| Spark plugs (B58 petrol) | BMW B58 plugs · gap/spec confirm in manual | Dealer schedules list 48,000 mi (or 4 years) | If the truck is near 48k and there's no record, do them now. Plug fitment below is listed for the BMW 340i B58; confirm against the INEOS parts catalogue.BMW B58 spark plug kit, set of 6 (listed for 340i B58; confirm Grenadier fitment) · FCP Euro ↗ |
| Fuel filter (B57 diesel only) | confirm in manual | Every 2 years per dealer schedule | Non-US diesels only. Replace if there's no record, and more often on questionable fuel. |
| Coolant | BMW LC-18 coolant (BMW 83195A42DF3 = Frostox HT-12), 50/50 with distilled water · capacity confirm in manual | Every 4 years per dealer schedule | Don't top up with generic green or older BMW GS 94000 coolant.

| Automatic transmission (ZF 8HP: 8HP51 petrol, 8HP76 diesel) | ZF Lifeguard 8 ATF · ≈10.6 L reported by an owner confirm in manual | Dealer schedule: check every 2 years, replace at 6 years. Owners plan a pan/filter at 40–50k mi. | Do a drain and pan/filter change (the filter is built into the pan), not a flush. The Grenadier pan has a second, smaller pickup port, so aftermarket aluminium pans may not match. Fill level at the right temperature: use the Offroad › Temperatures screen and keep the truck level.ZF 8HP pan/filter service kit with Lifeguard 8 (listed for BMW; Grenadier fitment unconfirmed) · FCP Euro ↗ZF Lifeguard 8 ATF, 1 L · FCP Euro ↗ |

Owners change it much earlier: one found metal flakes at 800 mi, and some trucks had it changed under recall at ~5,000 km. | O-ring-sealed drain and fill plugs, 15 Nm (owner-reported). Owners quoting the workshop manual say it calls for fill to spill; because the cooler lines drain back, some owners also measure what comes out so they know how much to put back.Fuchs Titan Sintopoid 75W-90, 1 L (buy 3) · FCP Euro ↗ |
| Front & rear differentials (Carraro axles) | SAE 80W-90 GL-5 · 2.1 L per axle (workshop-manual figure quoted on the INEOS Forum). Note: Agile Offroad's diff-cover instructions call for 75W-140. | First change at 12 months / 12,000 mi, then 60,000 mi per the US schedule as quoted by owners. Owners who wade or tow do it every 10,000 mi. | Remove the FILL plug first, because owners have snapped fill plugs after draining. 12 mm hex plugs (M22×1.5), 31 Nm; INEOS plug part GRA-5000-021220 (the O-ring isn't sold separately). The fill plug is magnetic. Same fluid with or without the lockers.Fuchs Titan Supergear MC 80W-90 gear oil, 1 L (buy 5) · FCP Euro ↗ |

| Power steering fluid (hydraulic Bosch box) | Penrite LDAS, as cited from an INEOS support document by an Australian owner on the INEOS Forum · confirm in manual | Check level and condition at every service | The recirculating-ball steering is hydraulic. Owners with big tires and heavy steering look at Owl's upgraded pump. Check for leaks at the box and pump. |
| Suspension retorque, body drains & recalls | Retorque suspension and body mounts; clear the body and safari-hatch drains | At purchase, then every annual service | Dealer first-service packages include a suspension retorque and drain clearing. Run the VIN for open recalls (door button 25V147, steering ball-joint nut 23V903, aux switch panel 23V828) before anything else. |
| Battery & charging | confirm in manual | Test at purchase and every service | Dealers include a battery health test in the annual service. Trucks that sat on a lot often have a tired battery, which causes odd electrical warnings. |
