Finding a dark puddle of oil under your car after parking can feel like discovering a mystery stain on your favorite shirt. It is worrying, inconvenient, and often raises one big question: Is my car in serious trouble?
For many drivers in Kenya, oil leaks are a common issue caused by wear and tear, rough road conditions, high mileage, or delayed maintenance. The good news is that most oil leaks are manageable if diagnosed early. In this guide, we explain why your car is leaking oil when parked, how to identify the source, and what practical steps you can take to fix the problem before it turns costly.

Car Leaking Oil When Parked: Common Causes
Oil leaks often become more noticeable when a car is parked because gravity allows oil to drip and collect on the ground. Below are the most common reasons behind this issue.
1. Faulty or Loose Oil Filter
Price impact: Low to moderate
Severity: Common and usually easy to fix
Why it causes oil leaks
The oil filter plays a critical role in removing contaminants from engine oil. If it is loosely installed, damaged, clogged, or fitted incorrectly, oil can leak out even when the engine is off. Over time, debris buildup increases internal pressure, which may force oil past weak seals.
Best use case for quick fixes
This is often discovered after an oil change or routine service.
Pros
- Easy to diagnose
- Relatively inexpensive fix
Cons
- Can lead to rapid oil loss if ignored
Car care tip: After every oil change, check under the car for fresh oil spots during the first few days. Catching a loose filter early can save your engine from damage.
2. Damaged Front or Rear Main Seals
Price impact: High
Severity: Serious if left unattended
Why it causes oil leaks
Your engine has two main crankshaft seals, one at the front and one at the rear. These rubber seals keep oil inside while allowing the crankshaft to rotate. With age, heat, and mileage, they harden, crack, and begin to leak. When the car is parked, oil slowly seeps out and drips onto the ground.
Best use case
Common in older or high-mileage vehicles widely used on Kenyan highways.
Pros
- Fix permanently solves a major oil leak
Cons
- Labor-intensive and expensive to repair
Car care tip: If you frequently top up engine oil without visible smoke or burning smells, have the main seals inspected.
3. Worn Valve Cover Gasket
Price impact: Moderate
Severity: Medium
Why it causes oil leaks
The valve cover gasket seals the top of the engine. When it fails, oil leaks from above and often drips onto hot exhaust components. This usually creates a strong burning oil smell rather than a large puddle.
Warning signs
- Burning oil smell
- Oil stains on engine sides
Pros
- Easier to fix than major seal leaks
Cons
- Can damage ignition components if ignored
Car care tip: If you smell burning oil after driving, do not ignore it. Early gasket replacement is far cheaper than fixing secondary damage.
4. Leaking Oil Pan Gasket
Price impact: Moderate to high
Severity: Medium to serious
Why it causes oil leaks
The oil pan gasket seals the bottom of the engine. Over time, it can crack or wear out, especially on cars driven on rough Kenyan roads. A leak here usually causes oil to drip straight down, leaving a puddle in the center of the parking spot.
Best use case
Common in vehicles with low ground clearance.
Pros
- Easy to identify
Cons
- Repair can be complex depending on vehicle design
Car care tip: Avoid hitting bumps and potholes aggressively. Impacts can damage the oil pan and accelerate gasket failure.
How to Identify Where the Oil Is Leaking From
Before rushing to repairs, it is important to locate the source of the leak.
Simple DIY check
- Park your car overnight on level ground.
- Place clean cardboard under the engine area.
- Check the drip location in the morning.
What the drip location tells you
- Front-center: Oil filter, drain plug, or oil pan
- Near front wheels: Possible axle or seal leak
- Spread-out stain: Leak from higher up running downward
A mechanic can also clean the engine and trace the exact source for a precise diagnosis.
How to Fix Oil Leaks When Parked
Easy fixes
- Tighten or replace a faulty oil filter
- Ensure the old gasket is removed during oil changes
Moderate repairs
- Replace valve cover gasket
- Replace oil pan gasket (may require removing other components)
Major repairs
- Replace front or rear main seals
- Requires advanced labor and professional tools
If you are unsure, it is always best to let a qualified mechanic handle the repair.

Conclusion: Don’t Ignore Oil Leaks
An oil leak is not something to panic about, but it should never be ignored. In most cases, the problem is caused by aging gaskets or seals rather than engine failure. Addressing leaks early helps protect your engine, saves money, and keeps your car reliable on Kenyan roads.
