118 miles, 2.2 engine hours since oil change. Last UOA is here. UOA history of this vehicle: https://bobistheoilguy.com/forums/s...c[title_only]=1&c[users]=Emperors6&o=date&g=1
Notes from slip: "Took oil sample with vacuum pump through dry sump dipstick tube after an oil change and a few street/highway driving trips. No track time on this oil. Also replaced oil cooler with a bigger one and changed oil thermostat from 180F to 212F. Oil temperature when sampling was around 207F. I drove about 40mins of mostly highway driving to test the new oil thermostat and burn off whatever contaminants I could before sampling. I had to stay in 5th gear (out of 8 gears) to get oil above 200F. Engine was not idled before shut-off. I waited around 13 min after engine shutdown before taking sample. It took a while since I had to fiddle with the right tube size.This UOA is for Driven DI50. I changed to it for the winter storage time".
