Service intervals
Intervals shown for the 3.6L Pentastar V6.
| Service | Every (km / mi) | Or every |
|---|---|---|
| Oil & Filter Change | 16,000 km / 10,000 mi0W-20. The oil-change indicator drives the interval (up to 16,000 km / 10,000 mi or 12 months); severe use drops it to ~6,500 km / 4,000 mi. | 12 months |
| Tire Rotation | 13,000 km / 8,000 mi | — |
| Engine Air Filter | 48,000 km / 30,000 mi | — |
| Cabin Air Filter | 19,000 km / 12,000 mi | 12 months |
| Spark Plugs | 96,000 km / 60,000 miThe 3.6L Pentastar runs a shorter plug interval than most V6s — about 96,000 km / 60,000 mi (iridium, 6 plugs). | — |
| Engine Coolant (OAT) | 240,000 km / 150,000 miMopar OAT (MS-90032) is rated for 10 years / 240,000 km / 150,000 mi, then every ~80,000 km / 50,000 mi. Never mix it with green conventional coolant. | 120 months |
| Automatic Transmission Fluid | 96,000 km / 60,000 miSevere-service interval (towing, off-road, heavy use). Lighter use goes considerably longer. | — |
| Brake Fluid | —A flush roughly every 5 years keeps a firm pedal. | 60 months |
| Differential / Transfer Case (4x4) | —75W-90 gear oil in the axles, ATF+4 in the transfer case; inspected on the normal schedule and changed under severe / off-road use. | — |

Rough estimates in CAD for scheduled-maintenance parts and fluids, based on typical prices — not live retailer quotes, and your costs will vary. Wear/replacement items (brakes, tires, battery) and diagnostics aren't included.
Fluids & capacities
Capacities are "with filter" and vary by engine — check your Jeep Wrangler's engine option below.
| Engine oil | 0W-20 full synthetic (dexos1) — 6.0 qt (5.7 L) |
| Engine coolant | Mopar OAT coolant (MS-90032)Do not mix with green conventional coolant — it gels. |
| Spark plugs | Iridium, ~60,000 mi service life (6 plugs) |
| Automatic transmission fluid | Mopar ZF 8-speed ATF (845RE) |
| Axles / transfer case (4x4) | 75W-90 GL-5 axles; ATF+4 transfer case |
| Brake fluid | DOT 3 |
Confirm the grade and capacity against your owner's manual before servicing — figures can differ by trim, drivetrain and market.
What each service does
Oil & Filter Change
Fresh oil and a new filter keep the engine protected. Jeep's oil-change indicator calls for service based on how you drive, capped at one year.
Tire Rotation
Rotating tires evens out tread wear — important on 4x4 models where all four tires should stay closely matched.
Engine Air Filter
A clean air filter protects power and economy; replaced around 48,000 km / 30,000 mi (sooner in dust or off-road use).
Cabin Air Filter
Filters dust and pollen from the cabin air, roughly once a year.
Spark Plugs
Jeep's Pentastar V6 is due for iridium plugs around 96,000 km / 60,000 mi. Fresh plugs keep it running smoothly.
Engine Coolant (OAT)
Jeep's organic-acid-technology coolant carries a long first interval before its corrosion protection needs renewing.
Automatic Transmission Fluid
Clean fluid keeps the automatic shifting smoothly; Jeep shortens the interval sharply for trucks that tow or see off-road duty.
Brake Fluid
Brake fluid absorbs moisture over time, lowering its boiling point; a periodic flush protects the brake system.
Differential / Transfer Case (4x4)
On 4x4 Jeeps the axle and transfer-case fluids protect the drivetrain; inspected rather than changed on a fixed interval.
These intervals are drawn from the 2020 Jeep Wrangler's manufacturer maintenance schedule for normal service. Your vehicle's owner's manual remains the final authority, especially for "severe service" conditions like towing, short trips or dusty roads. BoxKitz links you straight to the manufacturer's manual and live recall data once you add the vehicle.
