Honda Engine flush
Does My Honda Need an Engine Flush?
To engine flush or not, and how often? When there is suspicion of sludge in a Honda engine then it’s a good idea to do an engine flush.
Modern Honda’s that get regular servicing may also benefit from an engine flush and your mechanic could choose to do an engine flush at every service.
The premise being it will keep the Honda engine like new, by removing any deposits.
However, if you have an older Honda with high kilometres, there may be leaking seals buried under the sludge, if that’s the case it’s best to leave the gunk alone and wait until the Honda is ready for an engine rebuild.
The engine flush removes old carbon deposits and sludge from old oil that’s been sitting around and not vacating the engine whenever the Honda gets an oil change.
Sometimes it needs a little help to move it on, so the engine's oil-lubricated surfaces are smooth and gunk free.
Unless you have a sludge problem then an engine flush will generally be carried out as part of a Honda scheduled service. Which will cost an additional $20 - $100 on top of the service, depending on products used and time taken.
But if you do have a sludge problem and need to get an engine flush, that’s not part of a scheduled service, then it could cost $150 - $250, depending on the type of Honda you have.
