use diesel engine oil to flush......
not really dirty, flush one time
if real dirty, 2 -3 times depending ur wallet thickness
if less than 5 yrs car, proper maintenance jobs preferred...so u dun ned flush here n there

well, we can only use the x1r engine flush once or twice a year rite?![]()
some people said engine flush is for newer car use
older engine tends to hv more problems after use engine flush, its too clean...causing internal to leak combustion etc etc. u will be more headache then :)
why using engine oil to flush? its somehow cheaper or slightly expensive than engine flush, but it is safe to use. no matter how many times u flush wit engine oil, it wont harm ur engine for sure. but of coz, its not as clean as u use engine flush.
ngam..it may problem later if flushing engine too often...better good take care ur car is service on time 5000 km...the sludge dirty will drop by self...
