How much oil should a car burn between oil changes (2023)

How much oil should a car burn between oil changes

Out of nowhere, you may see your engine is consuming more oil than it was supposed to. If that is the case, there are most probably two reasons for this problem. First, there is a leak inside. Or, the engine is burning more oil than normal.

Isengine burning oilnormal? We will answer that later. But we think you will want to know the answer to the following question the most. “How much oil should a car burn between oil changes?” Read on to find the answer to this question and several others related to it. Find out the reason:Car losing Oil but no Leak or Smoke.

How much oil should a car burn between oil changes?

Well, there is not a unified answer. Even the manufacturers don’t match each other’s answers. For this reason, we will give three answers here.

BMW’s limit

As per BMW, it will be normal for your car if it burns 1 quart of oil every thousand miles. So, if you own a BMW car, you won’t have to worry even if your car burns 1 quart of oil every 1K miles. However, for a normal car, the average limit is much higher than this.

GM’s limit

By default, the normal consumption limit of a GM car is pretty much higher than BMW’s limit. If your GM car burns 1 or more quarts of oil in less than 2000 miles, you will get warranty service from the manufacturer.

Common limit

Normal consumption for cars other than BMW or GM is not a piece of unified information. It mostly depends on the manufacturer or dealer you are buying the car from. Some dealers may say you will get warranty services if your car burns 1 quart of oil every 1000 miles. Some dealers may state the limit at every 500 miles.

That is why you have to be careful whenever buying cars from local dealers or less popular brands. Skipping things like this may cost you a lot in the long run.

Why is my car burning oil so fast?

At first, you have to be clear about the fact ‘burning oil fast’. You can consider that your car is burning oil fast only if your car consumes 1 quart or more oil just within less than 1000 miles. If not, your car is in a normal state. You don’t need to worry much about this issue. However, the following are the probable reasons that your car may burn oil so fast-

(Video) 7 Engine Oil Myths Stupid People Fall For

Piston rings

Piston rings are very crucial parts of an engine. They don’t let enter excessive gasses into your engine’s crankcase. In simpler words, they are the shields of your engine’s combustion chamber. If the piston rings get out of shape and don’t work properly, the oil may enter the engine’s combustion chamber.

After that, the oil may burn inside, and you will eventually lose oil without knowing anything.

PCV valve

The PCV (positive crankcase ventilation) is another crucial part of your engine that keeps dangerous gases at bay. As soon as the gases enter into the PCV valve, it reroutes the gases back to the place from where they came, the combustion chamber.

If the PCV valve can’t do its job properly, it can suck oil inside. If that happens, you will lose oil by a huge margin. To get rid of this problem, you have to simply replace the PCV valve.

Head gasket

Another sealer of the cylinders is the head gasket. If the head gasket goes down, coolant will enter into the cylinder head. In this way, coolant will mix with oil, and eventually, your car will face poor idling.

The easiest way to differ the head gasket problem with the PCV valve is to see whether there is a coolant mix-up with the oil or not.

Valve seal

The job of the valve seals is to control the oil consumption system. In addition, it controls the valve lubrication too. If a valve seal goes bad, it will become one of the matters of your concern. Instead of doing the job it was supposed to, a damaged seal will leak oil into the combustion chamber.

Car oil consumption calculator

Using an oil consumption calculator is always a better option to calculate the actual amount of fuel consumed. Because without a calculator, you may not be able to calculate accurately if you get stuck in a traffic jam sometimes. During a traffic jam, the usual oil consumption is more than normal.

You can easily calculate your car’s oil consumption using the following formula-

Qy = ∑q + (Qз-Qсл)

Here, ∑q is the oil you have used within a certain period (cycle),

Qз is the amount of oil you use while refueling,

Qсл is the amount of drained oil at the time of replacement.

Engine oil consumption chart

Here is a chart of oil consumption that provides information from as far as the 1980s.

Average oil consumption per 1000 miles

We were talking about the safe limit ofcars that burn oil. Let’s see what the average oil consumption of a car per 1000 miles is. You are in a safe zone, or your car is burning oil normally only if your car burns 0.3 to 0.5 quarts of oil per 1000 miles. This is the average scenario for a normal car.

However, having a performance or modified car can make the scenario different. Performance cars usually burn more oil as these cars don’t focus on being fuel-efficient. For this reason, if you have a performance car, you should not expect this stat as an average.

Even if your performance car burns more than 1 quart of oil every 1000 miles, things are maybe normal. In this case, you have to cross-check the amount of oil you are losing with your manufacturer’s recommendation.

(Video) Synthetic Oil vs Conventional Oil - Which Type For Your Car Engine

So, unless your car is a performance or specialized car, you can expect the average figure of 0.3 to 0.5 quarts per 1000 miles in terms of burning oil.

Engine oil consumption no smoke – What does it mean?

Engine oil consumption generally means your vehicle will emit smoke. But your vehicle may still burn oil even if it doesn’t emit smoke or you don’t getaburning oil smell. If that is the case, the oil control ring extenders are most probably collapsed or worn.

What should you do if your engine consumes oil without smoke? Don’t worry much. The solutions are not that much different than those of normal situations. Diagnose your car. You may have to replace the PCV valve or valve seal.

Burning a quart of oil every 500 miles- what will happen

Is yourcar burning oil1 quart or more every 500 miles? It is pretty scary just to imagine this scenario. You should not expect this situation unless you have a very old model car. Cars from the 80s or 90s can give you this type of experience. Modern vehicles must not reach this type of situation by any means.

As we have already mentioned several times, you can easily expect the average figure of oil consumption of 1 quart per 2000 to 3000 miles. A quart per 500 miles means you are getting four or six times lower than the expectation.

Now, what are the outcomes of it?

If you have anoil burner car, you may face some serious problems. At worst, you may end up with a dead engine if you drive for a long time with this much oil consumption. And we are almost sure of the fact that you don’t want your engine ending up dead.

If you are lucky and quickly fix the faulty engine parts, you may get out of the situation by paying only a few bucks. We hope you get lucky in this particular case. But for that, you have to check upon the oil level every 300 miles or every week.
