Description

Genuine Comma · Part no. EF400M

Comma Engine Flush (EF400M) is a 400ml can of cleaner that goes into the old engine oil just before an oil change, for petrol and diesel engines. It loosens deposits inside the engine and helps free sticky valves and piston rings, so the fresh oil goes into a clean engine.

Good to know

  • When do I add it? Pour it into the old oil just before you drain it, then idle the engine for the time given on the can; don't drive the car hard or far with the flush in the sump.
  • What else do I need for the job? A new oil filter, a sump plug washer and enough of the right oil for a full refill; the loosened dirt leaves with the old oil and the old filter.
  • Will it cure a noisy or smoky engine? No. A flush cleans out deposits, but worn bearings, rings or valve seals need mechanical repair, so use it as part of a service rather than as a fix.

Which one?

To treat the oil between changes instead of cleaning before a change, the NAPA Engine Oil Treatment 300ML (NAD1010) goes in with the oil for petrol and diesel engines; for petrol engines that smoke, there is STP Smoke Treatment 450ml (64450EN06).
