To quieten top end use; Forte top end treatment added to 5w/40 fully synthetic oil + OE filter, within a few
days engine will be significantly quieter.
Used an oil flush about 10 years ago and within a week the engine just stopped, a con rod had overheated and
turned blue, dealer who rebuilt the engine mentioned debris dislodged in the oilways, so i have avoided them
Alternative is 6 month oil changes DIY in less than an hour.
