Hello folks. It is time to change the oil in our 2012 Nissan Versa. Nissan says 3750 miles for the severe OCI. I noticed that I could get Super Tech full synthetic and a Puralator classic for under $20. That was a better deal than a conventional oil and no name filter from the auto parts stores. I looked at the bottle and it has WPP on the bottom of it. That tells me that Warren is packaging the oil for my Walmart. Rather than fight over what motor oil and filter is the best ever made at any price, I have come to the conclusion that what really matters is that your oil and filter are changed like they should be. The motor oil exceeds the specs from the owners manual and the factory Nissan oil filter is a Chinese made Fram. I guess that I did not do too bad for under $20 using the factory 3750 OCI.
