bekker 7 Report post Posted August 7, 2009 Hi guys I'd be interested in hearing other experience and whether I should be checking anything? The thing is, I understand the capacity of the M20B27 with filter change is around 4.25 litres. Mine has consistently taken 5 to 5.5 litres at change. I've never had any issues with it so I'm not too worried but I thought I'd just see what people think. Any thoughts? Cheers. Quote Share this post Link to post Share on other sites
