Tires are down to 60 now. I had them higher a few months ago, but they've drifted down. I don't find any benefit above 60.
I always use Mobil1 5w20. This car calls for 5w30, but I use the lower weight for less friction. It's also what the other car calls for, so I use the same in both. Easier to stock only one in the garage.
My commute is rolling hills, 50-100 feet elevation change up and down. 10 miles, with a mix of 35, 45 and 55 mph speed limits. 3 stop signs and 4 traffic lights. I choose this particular route because most of it is multi-lane roads and I don't hinder traffic from going past.
I do Pulse & Glide (eoc) with a 25 to 40 mph spread (Scangauge says 25 mph average, but that's counting stops). I adjust that a little higher and lower in certain spots and for traffic. I drive as if I have no brakes - my best run I touched the pedal 5 times (including when I parked at work). That involves anticipating the light cycles so I can roll through on the green.
There's one spot, on a flat hilltop, where I roll along at ~10 mph for half a mile. Those neighbors give me looks.
