Valvoline Syn Power 5W30 (full synthetic) was pretty high on the list of tested oils. If you buy it at Walmart in the 5 quart jugs it's only $4.99 per quart which is a pretty good price for a full synthetic oil, especially since it tested as high as it did. I use it in my daily drivers and use NAPA Gold filters. In my bracket car I use Brad Penn 20W50 which is a partially synthetic oil. Some people refer to Brad Penn as a synthetic blend but it is not. I tried synthetic oil in my bracket car engine once and the oil pressure was way too low so I only us the Brad Penn in that car.
