There is a classic habit that is still often practiced by some car drivers, namely revving the engine before turning off the car. They say it keeps the battery strong and makes it easier to start the engine again later. But is that really true?

It turns out that this method is outdated and no longer necessary, especially if your car has a modern system.

Back in the day, when cars didn’t have computerized systems, revving the engine before turning off the car was believed to help charge the battery through the alternator. Additionally, the high engine RPM was thought to help distribute the last bit of oil before the engine completely stopped.

However, modern cars now use an ECU (Engine Control Unit) that automatically regulates oil flow and electrical systems. Therefore, there is no longer a logical reason to rev the engine before turning off the car.

It Can Actually Damage the Engine

Instead of keeping the engine healthy, the habit of revving the engine before turning off the car can actually cause damage. When the engine is turned off while still at high RPM, the oil level drops suddenly and drastically, causing engine components to rub against each other without sufficient protection. The result? Components wear out quickly, and engine performance may decline.

Avoid This If Your Car Has a Turbocharger

Especially for owners of turbocharged cars, be careful! The turbocharger needs time to cool down before the engine is turned off. If you rev the engine just before turning it off, the turbocharger can overheat and wear out faster.

So, the more advanced the car, the more you should abandon outdated methods that no longer align with modern engine systems.

Wastes Fuel and Increases Pollution

Besides making the engine more prone to damage, revving the engine before turning it off also wastes fuel and increases air pollution. The effect of adding electrical current to the battery is minimal, especially if the gas pedal is only pressed briefly.

It’s better to turn off the car normally, without revving the engine.

Tak Perlu Geber Gas Sebelum Matikan Mesin Mobil

Ada kebiasaan klasik yang masih sering dilakukan sebagian pengemudi mobil, yakni memainkan pedal gas (geber) sebelum mematikan mobil. Katanya sih biar aki tetap kuat dan mesin gampang nyala lagi nanti. Tapi, apa benar begitu?

Ternyata, cara seperti ini sudah ketinggalan zaman dan nggak perlu dilakukan lagi, apalagi kalau mobil kamu sudah pakai sistem modern.

Zaman dulu, saat mobil belum pakai sistem komputerisasi, geber mesin sebelum matikan mobil dipercaya bisa bantu mengisi daya aki lewat alternator. Selain itu, putaran mesin yang tinggi dianggap bantu sebar pelumas terakhir sebelum mesin benar-benar berhenti.

Tapi sekarang, mobil modern sudah pakai ECU (Engine Control Unit) yang secara otomatis mengatur aliran pelumas dan kelistrikan. Jadi tidak ada lagi alasan logis buat geber-geber mesin sebelum mematikan mobil.

Malah Bisa Bikin Mesin Rusak

Alih-alih bikin mesin sehat, justru kebiasaan geber gas sebelum matikan mobil bisa memicu kerusakan. Saat mesin dimatikan dalam kondisi putaran tinggi, pelumas turun drastis secara tiba-tiba dan bikin komponen mesin gesekan tanpa cukup pelindung. Hasilnya? Komponen cepat aus dan performa mesin bisa menurun.

Wajib Dihindari Kalau Mobil Kamu Punya Turbo

Khusus buat pemilik mobil bermesin turbocharger, hati-hati! Turbo itu butuh waktu untuk mendingin sebelum mesin dimatikan. Kalau malah digeber pas mau dimatikan, turbo bisa overheat dan lebih cepat rusak.

Jadi, makin canggih mobilnya, makin kamu harus tinggalkan cara-cara lawas yang nggak sesuai lagi sama sistem mesin masa kini.

Boros Bensin dan Nambah Polusi

Selain bikin mesin rentan rusak, geber mesin sebelum dimatikan juga cuma bikin boros BBM dan nambah polusi udara. Efek penambahan arus listrik ke aki memang ada, tapi sangat kecil, apalagi kalau gas cuma ditekan sebentar.

Lebih baik, matikan mobil seperti biasa, tanpa perlu geber-geber gas segala.
