Subject: Re: Synthetic Oil in older Saab

Well this is old knowledge. It is not true these days. When synthetics where new in the marketplace they caused leaks in older cars because the did not affect the rubber in the engine seals as ordinary oil did. So in worn engines were the swelling of the seals was esential too keep them from leaking , there was leaks when you switched too synthetic. This was tackled easily by modifying the synthetic so that it also had the same effect on the seals. That Is actually making the product less good for new cars then the unmodified product. Hence there is no reason not too switch. Synthetics are better and there are no real drawbacks. Tony W wrote: > I have seen synthetic oil recommended several times.
