Has anyone used the Valvoline $5.00 coupon for a 5 qt jug of oil?

Thanks. Always nice to save money. Engine oil is meant to be changed often - just like washing your hands. So more frequent changes with cheaper oil is a good deal. Actually you can just find the cheapest oil on the Walmart shelf. All oil comes out of the same hole in the ground and all oil gets extracted by the same technology in the same refineries. What people think about which oil is better is all advertising BS. They can't prove any of it. And synthetic oil is just not worth the cost.

btw. Don't believe any of the goofy advertising for gasoline either. All the gasoline in every station near you (and everyone else) comes off just one train or out of just one pipeline. Brand makes no difference, so buy the cheapest. And if you want to check if that is true, walk into any fire station near you and ask the Battalion Commander on duty. He will tell you about the one train or one pipeline near you.

VALVOLINE is made the WORST way of all , the WAX REDUCTION METHOD< and it ALWAYS makes sludge and varnish inside neengines! I woudl SAVE your money and use REAL OIL! Like MOBIL ONE 0W-30 or AMSOIL! NO CAR comes with VALVOLINE at the rfactory! NONE! Remember that!
