You check the dipstick a few weeks after an oil change and notice something worrying: the oil level has already dropped. It has no clear red flags; the vehicle continues to run like a regular car, yet you always seem to be filling up the engine oil much more frequently than usual.

Usually, high engine oil consumption cannot be overlooked by vehicle owners in Pakistan. Summer heat, city traffic jams, lengthy motorway trips, old engines, and inconsistent maintenance can worsen the issue. Although minimal oil consumption during the operation of some engines is normal, a sudden or noticeable rise often indicates an issue that warrants attention.

The first step towards avoiding costly engine repairs is to know where the oil is heading.

Worn Piston Rings Can Allow Oil to Burn

Worn piston rings are among the most common causes of excessive engine oil consumption, especially in older or high-mileage cars.

Piston rings form a seal between the cylinder walls and the pistons. This seal is used to maintain compression and prevent excessive engine oil from entering the combustion chamber. These rings and cylinder surfaces may wear out, however, as an engine gathers mileage.

Once the seal is compromised, oil can seep into the combustion chamber and burn with the air-fuel mixture.

Symptoms common to oil burning include bluish exhaust smoke, frequent oil top-ups, oil deposits along the exhaust, loss of compression, or decreased engine performance. In other instances, oil consumption builds up over time, and the driver might not realize there is an issue until the dipstick indicates a very large decrease between services.

The proper viscosity and a high-quality lubricant can help ensure that healthy engine parts are not subjected to needless wear, but engine oil cannot restore damaged piston rings.

Aging Valve Seals May Let Oil Enter the Cylinders

Valve stem seals play another role in oil control. They control the volume of lubricant that reaches the engine's valve parts and prevent excess oil from entering the combustion chamber.

Valve seals may harden or become damaged as they age, due to heat and constant use. The oil can then escape from the seals and enter the cylinders.

An automobile with worn valve seals may emit blue exhaust smoke, particularly when starting the engine after the car has been parked for a few hours. Smoke can also be detected after prolonged idling, then acceleration.

Since Pakistan's climate can expose engines to extreme operating temperatures, it is especially important to ensure the proper oil level and adhere to the recommended oil change interval as vehicles age.

External Engine Oil Leaks Can Reduce the Level Quickly

Not all cars that shed oil are necessarily burning it. In other cases, the oil leaks from the engine.

Engine oil leakage may occur around the oil pan, valve cover gasket, crankshaft seals, oil filter housing, drain plug, or other sealing surfaces. Only a small spill might leave just a few drops under the vehicle at first, but in a few weeks it can cause the oil level to drop considerably.

Other leaks are more difficult to detect since oil spills on hot parts of the engine and burns before it reaches the ground. Instead of a puddle under the car, drivers can smell burning oil when they drive.

When your oil level drops repeatedly, check the parking area for stains and the engine for any wetness or oily areas. Just pouring in more oil and not fixing an active leak merely covers the issue in the short run.

The Wrong Oil Viscosity Can Increase Consumption

The viscosity of engine oils varies with temperature, which is why manufacturers specify viscosity grades such as 0W-20, 5W-30, 5W-40, 10W-40, or 20W-50.

Running an oil much thinner than the engine maker recommends can lead to higher consumption in some engines, especially older ones with larger internal clearances. Nevertheless, it is not necessarily correct to switch to an unusually thick oil to cease consumption either.

The most secure way is to stick to the viscosity recommended by your vehicle manufacturer and take into consideration the age of your engine, its condition, the environment in which it operates, and its service history.

For modern petrol engines that require this viscosity range, one product available from the Atlantic Oil Store PK is Atlantic NEOTRIC ULTRA 5W-30 SP. It is also on the store list as an API SP engine oil expected to provide wear protection and help control sludge and deposits.

Aggressive Driving Can Increase Oil Usage

Engine oil consumption can also depend on your driving style.

High-speed motorway and long periods of high-RPM driving, coupled with frequent hard acceleration, generate more heat and pressure inside the engine. In such circumstances, there is a possibility that the oil will reach the consumption or evaporation sites.

It may be more noticeable when an engine is already worn.

Another challenge is the stop-and-go traffic in Pakistan's urban areas. Prolonged idling and repeated acceleration and deceleration may impose significant thermal strain on an engine. Drivers who frequently experience extreme traffic conditions are therefore advised to follow the dipstick rather than relying solely on the scheduled service. date

Fuel Dilution Can Affect Oil Performance

Fuel dilution is the entry of unburned fuel into the crankcase, where it combines with engine oil. The problem may be caused by short trips, cold-start problems, injector issues, incomplete combustion, and some engine failures.

The effective viscosity of oil can be reduced by fuel contamination, compromising its ability to sustain a protective lubricating film. Though fuel dilution may not necessarily manifest as an immediate decrease in oil level, poor oil may exacerbate engine wear and ultimately lead to increased oil consumption.

If the oil smells strongly of fuel or its level is abnormal, it is best to have it checked by a professional.

Engine Condition and Mileage Matter

A 150,000-km used engine would certainly not behave the same as the same engine when almost new.

Internal clearances vary slowly due to wear in parts. Problems with the PCV system, wear on the cylinder, broken seals, turbocharger failure in turbocharged cars, and a poor maintenance record can also lead to increased oil consumption.

This is why it may be deceptive to suddenly switch the oil grades without knowing the reason. To ascertain whether the issue is due to normal wear or a real mechanical fault, a mechanic might be required to carry out leak tests, compression tests, or other diagnostic tests.

Drivers seeking different viscosities can compare the engine oils and lubricants offered at Atlantic Oil Store, PK, which has mineral, semi-synthetic, and synthetic lubricants for various engine needs.

Can Better Engine Oil Reduce Oil Consumption?

Good engine oil can control deposits, minimize wear, and provide lubrication in harsh temperatures. But one should not have high expectations. Oil will not repair broken seals, severely worn piston rings, or damaged cylinder walls.

It is more important to select the viscosity recommended by the manufacturer and an appropriate performance specification than to choose the thickest available oil automatically.

For engines that require 5W-40, Atlantic NEOTRIC ULTRA 5W-40 SP is another fully synthetic engine oil for drivers who require this grade.

Don't Ignore Falling Engine Oil Levels

Overuse of engine oil is generally an early symptom and not an issue that should be addressed with frequent refills.

Aging piston rings and seals, external leakage, incorrect viscosity, heavy driving patterns, fuel dilution, and overall engine wear lead to a decrease in the level. The earlier the real cause is determined, the higher your chances of preventing more severe engine damage.

Check your dipstick periodically, particularly when traveling long distances; maintain the correct oil change schedule; and investigate any unexpected increase in oil consumption. Above all, use the grade and specification of oil recommended for your car, rather than attempting to conceal mechanical issues by using another lubricant.

An hour or two spent inspecting the oil today will save a far bigger bill tomorrow.
