New to me 4runner

Just got back from our first trip in the new to me 4runner. About 3,000 miles. Two people + about 200 lbs of luggage/gear. No major issues. Couple of small things. Fuel gauge is not accurate. Twice the low fuel light came on & DTE read something like 20. Filled up & only held 17 gallons. I know this is better than being that far off in the other direction, but is there any calibration I can do? Tires are 265/70R17 Dueller H/T, w/~200 miles on them when I left home. Speedo reads 4 mph slow compared to the Torque app, 2 mph slow compared Google Maps. I think Maps uses GPS & Torque uses what is reported via OBDII? Got about 18 mpg for the trip, running posted limit to 5 over and estimating correction for speedo error at 2%. Not great, but acceptable. LTFT showing around + 3-4. Does that seem about right? It has an aftermarket alarm on it. Not gonna discuss that here. It will be gone before next week!

 

Welcome Stan, I hope you get it sorted out
