After paying for premium gas for 250K miles due to rattling under stress on hills at high speeds, I tried a tank of regular. The truck has run perfectly and I can't tell a difference in mileage or power between regular and premium gas.
The tail and marker light problems are presumed to be associated with my 22 year-old Ungo alarm system.

337,000+ miles, and I'm loving it.
