I'm with Veg_Ian and Keefy on this. At 55, not being a regular mechanical bod, with a dodgy back, a wife who'll flay me if I get any oil on the drive (or flay me anyway), and I have a garage which I struggle to find time to get organised due to parenting, work and other household chores. So it is not quick for me and I thus tend to put off what I shouldnt put off. The Pela method could make life a lot easier for me AS LONG AS it is an effective alternative.
So, to return to the question, will the Pela method still provide a 'fit for purpose' replacment of old oil for new if it is only able - say - to remove 80% of oil. In a way, there is a precedent as oil filter is advised is only needing changing at every other oil change. The clear implication is that the 0.7 litre or so of dirty oil in the filter is OK to leave in the engine at every other change (and I suspect would alwyas be OK to leave, its just that the filter itself should be renewed at sensible intervals).
On that basis, what would your view be Haydn? Any others got a view?
Mike
Note to self: Must remember to buy up wholesale supplies of Pelas and offer them on ebay as Bongo Oil Change pumps
