Following up:
A few weeks ago I headed out and ran into problems. As I approached the Oregon border, some of the roads I wanted to take were closed. I left on the day some big California-Oregon fires started. Stopped in a small town, Weed, near the border and got some directions that would have allowed me to circumvent the road closures, although adding a couple of hundred miles to the journey.
Decided to grab a motel in Medford, OR, made a reservation, and when I got to the place my room wasn't available. The hotel owner/manager claimed he had no reservation, and when I showed him my phone with the info, he then said he had no rooms left. Because of the fires, rooms in the area were scarce, and the only ones I could find were around $250/night, more than I wanted to pay,
Checking on road conditions, the fires, and the weather, I decided to cancel the trip and I headed back home. Temps on the way up were 104- to 106-degrees along I-5. Being in an air-conditioned car, I didn't feel it at all, but when I got out to stretch my legs near Lake Shasta, that 106-degree heat hit me hard. WOW! The A/C worked very well and got quite a workout.
On the way back, fires were breaking out around Redding and I-5. I don't remember precisely, but I think about for or five blazes broke out near and along my route, and at one point a portion of I-5 was closed.
All-in-all, I drove about 700 miles that day, and happily. the car behaved very well. This was my first trip longer than 200 miles, and I discovered that for these longer drives, I'll need to get a cushion for my back and some padding on the armrest as after several hours it was uncomfortable on my elbow. I averaged about 32mpg, used absolutely no oil (M1 EP 2qts 0W-20, 3qts 5W-30), and was comfortable, steady, and quiet at freeway speeds. At one point I took it up to an indicated 100mph and held it there for six miles, and the car felt solid and capable of keeping it up for quite a while. There are about 2,300 miles on this OCI, and the oil level hasn't dropped a bit.
I still want to make that long road trip, and am thinking about the early fall, and maybe a different route and destination.
