“I change my cars ( 2010 diesel Freelander 2 ) oil twice a year, so the oil never gets old but, this flush makes a difference as when it's not used the oil looks dirtier when used it is used so must help clean the internals.”
“I always use an engine flush on a new-to-me car when servicing myself for the first time, and i trust millers ouls to do a great job, easy to follow instructions, then fill up with millers xf oil.”
