How to check and top up engine oil level for longer life

Engine longevity depends not only on the quality and specifications of the oil that meet the automaker’s requirements, but also on keeping its level in check. Many drivers overlook this, yet it largely determines how long and trouble-free the power unit will run. Together with experts from lubricant maker Teboil, SPEEDME.RU looked at how to find the right amount of oil and help the engine last as long as possible. In everyday driving, the oil level is that quiet variable that often separates healthy engines from tired ones.

Why does oil level matter?

Engine oil doesn’t just lubricate. It also shields components from wear, carries away heat and helps seal the unit. If there’s too little oil, friction surfaces start working nearly dry, which can accelerate wear and even lead to seizure.

Overfilling isn’t any better. Excess oil raises pressure in the system, increases the load on seals and gaskets, and can ultimately cause leaks.

How much oil does your engine need?

Checking engine oil level is a key part of routine maintenance. The most reliable method is the dipstick: the level should sit between the MIN and MAX marks. It’s advisable to do this every 500 km. Modern cars also have sensors and trip computers that let you monitor oil level electronically. That interval is a pragmatic habit for everyday use.

Each engine has its own calculated oil capacity. You’ll find it in the owner’s manual, on the manufacturer’s website or at an authorized dealer. Make sure you consult the figures for your exact model and engine.

On average, passenger cars take from 3.2 to 6 liters of oil. Crossovers and SUVs need more; diesel versions can require over 9 liters. For example, a LADA Granta (1.6) needs 3.5 L, a Hyundai Solaris (1.4) 3.3 L, a Toyota Camry (2.0) 4.4 L, while a Toyota Land Cruiser 200 with a diesel V8 takes 9.2 L.

Too little oil leads to overheating and wear, while too much can cause foaming and a drop in pressure. So fill strictly to spec. This simple rule extends engine life and helps avoid costly repairs.

How to top up engine oil correctly

The basic routine for checking and topping up oil is the same for most cars. Step by step:

1. Park the car on level ground.
2. Let the engine sit switched off for at least 10 minutes so the oil can drain into the sump.
3. Open the hood and check the level with the dipstick. It should be between MIN and MAX. Then wipe the dipstick with a clean cloth and check again.
4. If the level is below the minimum, add oil gradually in small portions to avoid overshooting.
5. If you did overfill, correct it by draining a little from the sump or extracting it with a vacuum pump through the filler neck.
6. Start the engine and warm it up to operating temperature. Then wait a bit for the oil to return to the sump and recheck the level with the dipstick.

Practical tips

• When checking the dipstick, look at the oil’s consistency: it should be uniform, free of impurities and dirt. If it isn’t, it’s better to replace the oil.
• When changing oil yourself, initially leave about 0.5 L below the specified volume, since up to 10% of the old oil can remain in the system. After checking the level, top up the remainder.
• Buy a small reserve of engine oil so you can top up if needed. A 1-liter bottle is usually enough. Don’t forget proper storage conditions.
• Check the oil level at least every 500 km. Keeping a steady eye on the car’s condition helps avoid unexpected expenses.
