Yes, you can. However, to improve the cleaning effect we recommend using it with a full fuel tank.

It provides excellent clean effects for all types of the gasoline engines.

We recommend to use it every 5,000km or 6 months whichever comes first.

"It is expected to clean the exhaust gas due to removing various deposits on engine internals.
However, this improvement does not promise the cleanness equal to the new condition of a car."

"The effect continues while gasoline contains DDR.
DDR provides protection from contamination while it is on a metal surface, however the engine gets dirty gradually. We recommend using DDR regularly."

It might be difficult to feel the exact effects when the car is new however regular use will help to prevent the deposits providing turn solid.

"It will be very effective but just onetime use may be not enough to remove many adhered solid deposits.
If you use it with engine which is extremely dirty, it may give you the feeling that the engine condition becomes worse when too many melted deposits flow into the combustion chamber.
For this measure, we recommend using this product regularly.

Do not mix DDR with other products. It will not improve cleaning effect, and it may lead serious damage to the engine due to chemical reactions.
