Was in my local Wal-mart in Austin TX this morning and I found they had a clearance sale of $2 a quart and $9 for the 5 quart jug of the Pennzoil Pure Plus Europe 0W-40 all dated Jan 2017. I have a 2007 Chevrolet Impala 3.5 Flex fuel (looks brand new still) and a 1996 Ford Taurus 3.0 OHV engine that is my daily driver to work. I have been using synthetic 5W-30 and 10W-30 depending on sales. Would there be any concern to run back and purchase this oil and use them in both cars?
