I've run it a number of times before, in both of our vehicles. My Honda's engine was rather loud on this oil, as it is on all SOPUS synthetics for some reason. The Acura's engine wasn't any louder, but I prefer to run the same oil in both. Mobil 1's AFE line 0W-20 and 0W-30 run quiet in both of our cars, so that's what I'm using now.
