I'm using Microgard but I'm wanting to use a different one on the next oil change because Microgard doesn't have an anti drainback valve and there are dry starts when I start the engine. I know that because the oil light comes on for 2-3 seconds when I start the engine when it's cold. Microgard does good with keeping the oil clean but I don't like it that it allows all of the oil to drain back into the pan. Does Fram ultra have an anti drainback valve? How good does it filter the oil? I use Mobil1 full synthetic high mileage and change it every 5000-6000 miles.
