Dual Flow Oil Filtration
A special treat in store for Scandinavian Blue?
I am, by nature, sceptical of most hair-brained schemes that seem to come along every five minutes these days. They promise everything from a stress-free existence to whites so white you can see them from space. But last week I was introduced to a very forthcoming and intelligent gent by the name of Alan Roper.
He has developed a system of dual flow oil filtration for cars that, I believe, any Saab/Saab Turbo enthusiast will find very interesting and appealing.
The system in question has been available for a while now but only for industrial oil filtration. However, Mr Roper has created a similar system that can be used to extend oil and engine life on motor vehicles.
Rather than having engine oil flowing through one filter, it is made to flow through two. The first filter works in exactly the same way as a standard oil filter, ‘no news there’, but the second has motor oil pushed through it by the engine’s oil pressure whereupon it is then returned to the sump via an oil feed pipe and an adaption that takes the place of the sump plug.
So what does this system mean in practice? Well, because the engine oil is now doubly filtered, it will last longer (you may never need to change your oil again). Good news when you consider that a decent engine oil can cost £30 for 5 litres. Secondly, because the oil stays contaminate-free, the engine and turbo are much better protected.
So, what maintenance is required to the system? You change the primary and secondary filters every six months, no big deal as they only cost about £6! And that’s it!
Although the system has not yet been produced in really big numbers, it is still a bargain at around £250 – and it can prevent the change of a turbo or even an engine.
This system can also prevent the annoying sludging up of 9-5 and 9-3 engines keeping them in top condition too.
For us Classic 900 fans this system could well be a godsend, so I’m having one put onto my Scandinavian blue in the next week or so. I’ll keep you posted how it gets on.
Happy motoring
