RIZOIL prevents sludge formation.

RIZOIL is a very durable engine oil.
So the engine oil will stay clean for a long time and will control

“Carbon and Sludge.”

Engine oil remains clean for a long time, reducing carbon and sludge and extending engine life.

and traveled 120,000 km

An engine that changed oil for other products every
10,000 km and traveled 100,000 km

Carbon and sludge can damage the engine.

Black and degraded engine oil generates carbon and sludge.

It is late for changing after the engine oil turns black.It is necessary to change the oil before the performance of the oil decreases.
Because using the degraded oil will gradually accumulate damage.

RIZOIL is a very durable engine oil.It prevents sludge and keeps the inside of the engine clean forever.

Sludge inhibits engine oil flow

If oil change is delayed, sludge will be accumulated little by little. The oil passage is only 2 mm. When the sludge blocks the passage, noise may be generated from the engine or the engine or the engine itself may be destroyed.

sludge

Engine oil that has become black gradually sludge and accumulated in the engine.

Using black and degraded engine oil will cause white smoke and oil consumption.

White smoke and oil consumption are caused by Carbon and sludge.

The condition of the piston
that caused white smoke and oil consumption.

carbon

When engine oil darkens, a large amount of carbon is produced.
In the combustion chamber. The adhesion of carbon is not only the decrease in engine power.
Causes consumption of white smoke and oil.

piston_clinder

This piston is about 100,000 km traveling the 1999 Honda Civic Type-R.
It is an engine where sludge adhered to the groove of the piston ring and white smoke was generated. And oil consumption is a serious problem.
To prevent problems such as white smoke and oil consumption, an oil change is required before the engine oil becomes black.
RIZOIL is very useful for that.

Engine oil durability is important

The image is for 20,000 km without oil change. As you can see, it can be confirmed that it has not deteriorated in black even after traveling 20,000 km. Extremely durable engine oil. Because it does not deteriorate black, sludge and carbon can be suppressed.

※ It is not recommended not to change the oil for 20,000km.
