  Can we just clarify Rory's previous answer. Electric pressure washers do not generally require the gearbox oil to be topped up or replaced during there normal working life. However if during disassembling the machine oil is allowed to spill from the gearbox it is important for this to be replaced or the gear box will quickly wear and fail. Sorry for any confusion our previous answer may have caused.

• You can buy Karcher oil at, I believe, £34 pounds odd a litre, or use a good quality multigrade engine oil, which is just the same. Look on Youtube under Karcher repairs. By D.R. - Sheffield - 14 July 2015

  Ref Colbee comment. We mistakenly stated that electric pressure washers do not contain oil. The link given to Stock Number: ES538165 is an oils approved for pressure washer pumps and is suitable.

• Sorry, I'm a latecomer to this post, but I beg to differ with the response by staff-member Rory on 3/6/2011 who stated that an electric washer does not need oil; surely, in an electric washer, the swash plate chamber contains oil which is easily lost if the retaining bolts are loosened/removed and the motor is not kept upright.

  Hi Softy, if you have a petrol pressure washer, the oil you need to use to keep the engine lubricated can be found here: http://www.espares.co.uk/parts?k=pressure+washer+oil. If you have an electric washer, you won't need oil.
