This is a very recent UOA from my 2021 Ford Ranger 2.3 Eco at 48,600 miles after a 6,000 mile interval using Motorcraft synthetic blend 5w30 and a Motorcraft oil filter. The oil life monitor still showed 37% left. During the interval, the truck was driven towing a 2000lb trailer 750 miles to and from New Mexico in 100 degree temperatures and later making the same trip in 30 degree temperatures. The rest of rest of interval was medium and short trips around my home area. I don't drive many very short trips around town. I usually change the oil every 5,000 miles but had to stretch this one to 6,000. It looks like Motorcraft synthetic blend oil is fine for 5,000 mile intervals with my truck. I thought this UOA would be interesting because of the towing and extreme temperatures.
