well I have been using motorcraft 10w30 in 4.6 ford since last spring, I was buying the oil from the local autozone, well I switched to 5w-30 motorcraft from walmart at 2.08 a quart. the price is lower. Do you think that walmart oil is the same oil as the oil from autozone or a ford dealership considering the lower price?
after using motorcraft oil for 9 months I came to the conclusion it's better in my car than mobil drive clean and penzoil dino, start ups are quieter with the motorcraft oil. it also burns less oil, engine has 190,000 miles on it.
But after the oil change last week and switching to walmart 5w-30 it doesn't seem as quiet on cold start up as the old motorcraft 10w30
all of this oil is the syn blend, no old stock
