By finding the problem early and using the right engine oil, you can reduce oil burning, protect your engine, and save money on costly repairs.

What Is Normal Oil Consumption?

Oil consumption is how much engine oil your car uses while driving. It’s usually measured in deciliters (dl) per 1,000 kilometers. There isn’t one exact number where oil use becomes “too much” because it depends on the engine and the manufacturer’s rules.

For most passenger cars, everyday oil use is between 0.05 and 3 dl per 1,000 km. Newer cars usually burn less oil than older ones. Their allowed oil use is often 0.05% to 1%.

For utility vehicles, the regular oil use is a bit higher, usually around 0.25% to 0.3%.

What Causes Excessive Oil Consumption?

There are many reasons why an engine might start using too much oil. Here are some common ones:

Using the Wrong or Low-Quality Oil

Every engine needs a specific type of oil. If someone uses the wrong blend, it can damage the engine and make it burn more oil. For example, oil that’s too thin (low viscosity) can cause more heat and friction, which harms the engine.

Not Changing Oil on Time

If someone skips regular oil changes, dirt and debris build up over time. This makes the oil burn faster and can even lead to early engine damage.

Oil Contamination

Sometimes, harmful substances like dirt, fuel, or tiny metal particles can get into the oil. This makes it less effective and increases oil use.

Using the correct engine oil and adhering to the recommended service schedule helps reduce oil consumption and maintain the engine’s health.

Signs Your Engine Is Burning Oil

Catching the signs early can save you from expensive repairs. Watch out for these warning signs before the problem gets worse.

Thick Exhaust Smoke

If you see blue or gray smoke coming from your exhaust, it’s a significant clue. This means oil is mixing with fuel and burning. Every day, smoke is light, but when oil burns, it changes color. If you notice this smoke, especially when you speed up, get it checked right away.

Adding Oil Too Often

Are you filling up the engine oil more than your car’s manual says? That’s a red flag. It could mean your engine is burning oil inside. While leaks can also cause this, burning oil is a common reason.

Bad Smell from Exhaust

A strong, burnt smell coming from the exhaust is another sign. It happens when oil leaks into the engine and burns. This smell often comes with smoke or weaker engine performance. Don’t ignore it—get your car inspected.

Diagnosing the Problem

Finding the real reason why your engine is burning oil is significant. Here are some simple ways to spot the issue.

Check the Spark Plugs

Spark plugs can show early signs of oil burning. If they look dirty or oily, it means oil might be getting into the engine. Look for:

  • Black, sticky stuff on the tip.
  • A burnt oil smell around the plug area.
  • Trouble starting the car or engine misfires.

If you find these signs, replace the plugs and fix the main problem to stop it from happening again.

Do Compression or Leak-Down Tests

These tests help find deeper engine problems.

  • A compression test checks the pressure in each cylinder to see if the rings or valves are worn out.
  • A leak-down test uses air pressure to find where leaks are happening.

These tests need special tools and are usually done by a professional.

Check Oil Levels and Quality

Watch your oil level and how it looks.

  • If your oil is dark, thick, or smells burnt, your engine may be overheating or leaking.
  • A low oil level could mean a leak or burning inside the engine.
  • Foam your or strange-colored oil may mean other engine problems.

Keep a record of what you see. It helps the mechanic fix the problem faster.

How You Fix Oil Burning in Your Engine

When your engine starts burning oil, you know you need to act fast. Here are some simple ways you deal with it and keep your car running strong.

Repair or Replace Worn Parts

Sometimes, parts like piston rings, valve seals, or gaskets wear out and cause oil to burn. Here’s what you usually do:

  • Piston Rings: If these are bad, the engine needs to be opened up. You leave this job to a mechanic.
  • Valve Seals: These can often be replaced without removing the whole engine.
  • Head Gasket: If this is blown, you get it replaced to stop both oil and coolant leaks.

Using good-quality parts is always worth it. It saves your money in the long run.

Fix the PCV System

A clogged or broken PCV valve can also make your engine burn oil. Here’s how you handle it:

  • You find the PCV valve near the valve cover or intake manifold.
  • You check for cracks or clogs in the valve and hoses.
  • If it’s damaged, you replace it right away.

Keeping the PCV system clean helps prevent this problem from recurring.

Use High-Mileage Engine Oil

For older cars (over 75,000 miles), you switch to high-mileage oil.

  • It has special additives that help stop minor leaks.
  • It keeps the oil thicker, so less of it seeps into the engine.

This doesn’t fix major problems, but it’s a good way to slow down oil burning in older engines.

Why Your Engine Burns More Oil

Sometimes your car starts using more oil than it should. Here are a few reasons why that happens and what you notice when it does.

Damaged Piston Rings

Piston rings keep oil from slipping into the engine’s combustion chamber. When they get worn or damaged, oil leaks through and starts to burn. This results in blue smoke, reduced engine power, and poor acceleration. You also notice more oil burning than normal.

Old Engines

New engines usually use less oil. But as your engine gets older, the parts wear out. Small leaks start to show up, and the engine uses oil faster. You always check your oil use and compare it to what’s considered normal for your car.

Worn Seals or Gaskets

Seals and gaskets deal with a lot of heat, so they break down over time. When this happens, oil leaks out while you drive. You find yourself topping off the oil more often. The good thing is, fixing gaskets is not too expensive, and it helps the engine run better and last longer.

How You Know Your Engine is Using too Much Oil

Sometimes it’s not easy to tell if your engine is burning too much oil. Here are some signs you look for:

Blue Smoke

If you see blue or gray smoke from your exhaust, that means oil is burning inside the engine. This can happen because of leaking piston rings, worn cylinder walls, or damaged seals. If the smoke keeps coming, you’ll get a mechanic to check it properly.

Low Compression

Low compression tells you something is wrong with the engine parts, like the valves or piston rings. A compression test helps find this problem. To do it, a special tool goes into the cylinder, and the engine needs to be warm. The pressure should be over 100 psi per cylinder, and the difference between cylinders shouldn’t be more than 10%.

Carbon Build-Up

Sometimes, oil burns inside and leaves carbon deposits on spark plugs or valves. This is often caused by bad oil or damaged piston rings. You know this is a warning sign that needs attention.

Coolant Going Bad

If oil mixes with the coolant, it makes the coolant look dirty or cloudy. This also affects how well the engine stays cool and can cause more oil to burn.

How Do You Know If Your Car Is Using Too Much Oil?

You can usually tell if your car is burning oil by checking the oil level with the dipstick or watching for a warning light on the dashboard (if your car has one). Sometimes, you see blue smoke coming out of the tailpipe, which means oil is burning in the engine. Other times, you might smell burning oil if it leaks from a head gasket or valve cover and drips onto the hot exhaust. The smell is strong, like fresh asphalt at a construction site.

A little oil use is regular, even for new engines. Usually, cars use about 0.05 to 3 dl per 1,000 km (0.0052–0.317 quarts per 621 miles). But if it’s using more than that, you know it’s time to have it checked.

Why Does Your Car Use Oil?

Here are some common reasons:

  • Your car is old, and older engines naturally use more oil.
  • You might be using the wrong type or poor-quality oil.
  • Worn head gasket.
  • Worn piston rings.
  • Worn valve guides.
  • Leaky seals or gaskets, like those around the valve cover or spark plugs.

How You Make Your Engine Last Longer After Oil Consumption Problems

Sometimes fixing an oil consumption problem costs more than it’s worth. You know people who keep topping off their oil instead of spending thousands on repairs. For example, if the engine runs fine, doesn’t leak, and only burns about a quart of 10W-30 a month, they’d rather spend an extra $10–$15 than do a major repair.

But if you want your engine to last longer—whether the issue is already fixed or you want to avoid it happening again—here’s what you do:

  • You always use the recommended oil type and viscosity (like 10W-30) listed in your car’s manual. Synthetic oil is a bonus, but not always a must.
  • You get regular oil changes (about every 5,000 miles, depending on the car).
  • You replace your coolant on time so the engine doesn’t overheat.
  • You keep up with parts like spark plugs, intake seals, PCV valve, and air filter when needed.

Taking these steps saves me money in the long run and helps your engine stay healthy.

Final Takeaways

Oil burning often shows up as blue smoke from the exhaust, a sharp burnt smell, or dirty spark plugs. Leaks, however, usually leave oil spots under the car.

Knowing why your engine is burning oil is the first step to avoiding expensive repairs and keeping your engine running longer. Regular check-ups and the use of high-quality engine oil are key. Fubex Lubricants offers a range of premium engine oils designed to protect your engine, reduce friction, and help minimize oil consumption.

Too much oil consumption can be a sign of deeper engine problems. As soon as you notice the first signs, get your car inspected by professionals to find the cause.

Most importantly, always choose high-performance engine oil. Fubex Lubricants is committed to providing advanced engine oil solutions that meet modern standards and help keep your vehicle in top shape.
