oil cleaner suggestions

[Clansman]

Hi everyone,

Any suggestions for a good oil cleaner?

I intend to change the oil on my 535 but I would like to add something to give the engine a little clean up just before draining it. Now there are plenty of options, some of them imply 2 oil changes...

Any no-brainers?

Thanks in advance;

Doesn't really need anything if oil changes have been done often but if not lob some cheapo oil in for a couple of hundred miles and change it for decent stuff after.
