Another take on it is that it's 13 hours from SF to Seattle if you took I-5. I did much of OR once at about 110mph as we were following a truck doing the same. Depending on the make/model of your car, you can often get away with 10% over as that's what some car mfg's have for their speedometer and the feds say it's okay. In WA there's also a 5% tolerance for the radar guns.
Also keep in mind the pump-your-own-gas thing in OR can be a major hassle. Make sure you have a full tank in the evening. Finding gas after 6pm can be very, very difficult. Same on holidays. I made the mistake of trying to drive through OR on Christmas day. I had to try several towns off of I-5 before I found one with an open gas station. I don't know why I didn't run out of gas, the light was on for a very long time.
