[pedrofromredro]

I'm looking to do a oil change on my 250 tomorrow myself.would it do any harm putting a flush in the engine as at the mo I get a very slight rattle on startup from cold.help don't want to cause any damage lol

It won't do any harm,all you do is add it to your old engine old,start the car let it run for 10 to 15 minutes and then drain it oil and replace with new oil,hope this helps.

I have always used Wynns engine flush - Halfords stock this

No issues in the years I have used it
