Question: After Oregon went to requiring 10% ethanol in the fuel, (of which I do not find eco-friendly), I have had to replace 2 fuel pumps in my 95 900 SE Turbo. Although Saab's owner manual states that this is OK for the car, I do not agree. The problem with the ethanol and the fuel pumps, along with substantial loss in fuel mileage leaves me seriously doubtful about the OK for ethanol in the fuel. This actually does not apply just to Saabs, but have known most mechanics replacing many fuel pumps, along with injectors also.
Fortunately, they now allow us to purchase (when available) non-ethanol premium fuel for regular use. Trust me, I do use it exclusively in spite of the higher price. The net increase in fuel mileage alone makes it cheaper even before the fuel pumps. Also, walking at 11 pm at night in sub-freezing temps is not my favorite past time.
Due to the abrasive nature of ethanol, along with it's ability to absorb water, if you are forced to use the ethanol laced fuel, it is recommended to change fuel filters more often (annually) and I have been using Lucas Fuel Additive (not too expensive) with every fillup to keep everything clean and lubricated in the fuel system. So far, no repeats.
