Motul Engine Flush for Motorcycles & Scooters – Removes Sludge & Deposits Before Oil Change

If your engine feels rough, noisy, or you’re switching engine oil grades, Motul Engine Flush helps clean internal deposits safely before an oil change. Designed specifically for motorcycles and scooters, this flush restores oil circulation and prepares your engine for fresh oil. Genuine Motul product, packed and shipped by Under The Hood.

Over time, motorcycle and scooter engines build up sludge, varnish, and carbon deposits—especially in stop-go traffic, short rides, or when oil change intervals are stretched. These deposits restrict oil flow, increase friction, and can make the engine feel noisy or sluggish.

Motul Engine Flush is formulated to be added to used engine oil just before an oil change. During a short idle cycle, it dissolves harmful deposits and suspends them safely in the old oil, allowing contaminants to drain out completely when the oil is removed. This helps your new engine oil work at its full potential from the very first kilometre.

Unlike generic flushing agents, this product is designed for motorcycles and scooters, including high-revving engines and compact oil passages. It is safe for seals when used exactly as recommended and is especially useful when:

• switching oil brands or viscosity grades,

• reviving neglected engines,

• preparing engines before premium oil upgrades.

Used correctly, Motul Engine Flush improves engine smoothness, reduces harsh mechanical noise caused by oil contamination, and promotes longer engine life.
