What's the point of leaving a filter-full of dirty oil in the engine? Granted, it's just a little-bitty filter, but still...tuscan_thunder said:my thoughts are that if you change the oil more regularly than advised, and use an engine flush, then just change the filter at the stated intervals.
engine flush is a couple of quid for a can and is simple to use.
better doing changing oil and not filter than not doing either. it's not going to do any harm really is it?
