Yup, agree with that Tony.

I agree I wouldn't use engine oil either especially when you won't get all the oil out when you do a change, So another words there would be engine flush in the engine being run for however many km's with engine flush in the oil/engine.. 

[Hooli]

More agreement here.

An oil change with filter is 4.5l , a dry build is 5.7l. sod leaving that much engine flush in it. Besides, mines still clean in the cam area after 167k miles so there's  no need for engine flush.

Agree, no flush needed.
