So what exactly is " quality motor oil " ? http://jiffylube.com/AutoServices/srv_SignatureServiceOilChange.aspx?WSCID=1 Are you saying that Jiffy Lube will use synthetic if you bring them a Saab ? > Yes, there are bonehead penny pinchers on both sides of > the Atlantic that may try to get by on the cheap, but please refrain > from generalizing about things in the US since you quite obviously don't > have any real experience here. So.... Why is it that there is this constant debate on the topic ? I've not heard a single european poster claim that oil changes above recommended service interval are *needed* when using synthetic oil.

I was interested to see if the idea of regular filter changing had some support. It makes some sense technically. My total cost of a oil and filter change vs filter only is very different to the figures you mention. Graham
