Jeep Compass: Tigershark oil consumption and low oil pressure — engine can stall while driving

The Tigershark petrol engine in this Compass uses hydraulic valve actuators that depend on oil pressure to work at all, which makes it unusually intolerant of running low on oil — and it has a documented appetite for oil between changes. When the level falls far enough the pressure drops and the engine can stall while you are driving it. Jeep issued a recall covering oil pump failure causing exactly that, but the underlying oil consumption is a characteristic of the engine rather than a defect that gets fixed once, so a buyer's real job is to find out how much oil this particular car uses and whether the owner has been keeping up. Excessive consumption on this engine has been linked to engine damage, and it is the single thing most worth asking about honestly.

• Oil level well down on the dipstick between services
• Oil pressure warning light, especially at idle when hot
• Engine stalling while driving, or cutting out at low speed
• Ticking or tapping from the top of the engine, worst when the level is low
• Blue smoke from the exhaust under acceleration

1. 1

   Check the oil before you do anything else, on a cold engine standing on level ground, and pay attention to exactly where the level sits rather than just that some oil is present — on this engine a level near the minimum mark is the finding, not a technicality.

2. 2

   Look at the oil's colour and how thin it feels.

3. 3

   Ask the seller directly how much oil the car uses between services and how often they top it up; owners of these usually know, and a straight answer of "about a litre" tells you a great deal.

4. 4

   Ask when the oil was last changed and check it against the odometer.

5. 5

   Be there for a cold start and listen for ticking or tapping from the top of the engine, and watch the dash for the oil pressure light both at start-up and again at idle once fully warm.

6. 6

   Ask whether the car has ever stalled while being driven, and ask whether the oil pump recall has been completed — a Jeep dealer will confirm that against the VIN for free.

7. 7

   If a workshop inspection is possible: an oil pressure test tells you where this engine actually stands.

$0 to $7,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “How much oil does it use between services, and how often do you top it up?”
• “Has the oil pump recall been completed on this VIN?”
• “Has the engine ever stalled while you were driving?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
