Top Engine Cleaner, The decarbonizer in a spray can!

Top Engine Cleaner (TEC)

Top Engine Cleaner is one of the best ways to clean the carburettor and combustion chambers and will give back your lost power. It is an invention of Harry Omoto to dissolve carbon and was used in Japan for years by brands like Nissan Toyota and Honda.

In the 70’s Tecflow bought the recipe and rights from Bar’s Leaks out of the US. So Tecflow was the first company who sold Top Engine Cleaner.

Top engine cleaner cleans the “respiratory of the engine “.

Inject it into the air intake and all pollution and dissolved carbon comes out with the exhaust. This works for diesel and petrol cars but is not without any risk. The best and safest way to have it done is by a mechanic. A diesel with a small engine will start running on higher rpm when you spray it in the air intake so don’t spray it all in at once. A petrol car has a signal wire which you don’t want to hit.
