and was just curious what you guys recommend for oil and fuel. I used power premium in my 1994 900se, but noticed some stalling and extraneous rattles. Switched back to 85 octane and it all stopped. Just wanted to know if the power premium would be better. Also curious if fully synth would benefit me more in terms of motor longevity. A local mechanic told me to only use fully synth in H.O. motors. Thought I would ask you saab experts for advice. Thanks.
