Recycled oil
Does anyone know for a fact if wallmart synthetic oil uses recycled oil or is it virgin oil? Many thanks

Who can provide proof of an oil related engine failure ? It simply isn't that big a deal nowadays what brand you run.
I am less concerned with a catastrophic engine failure than normal engine wear. All of our 4 vehicles have 135K+ miles on them. I have used synthetic (mostly Mobil 1)since the early 1980s. Studies show that there is less engine wear with synthetics, especially at cold startup (which accounts for the majority of engine wear.
If you intend to keep a car/truck for 100K miles or less, then any oil will be sufficient. Most of the advantages of synthetic show up after 100K miles as reduced engine wear, which puts off the point where you start burning oil due to piston ring wear, less slop in bearings, etc.
More and more manufacturers are specifying synthetic or synthetic blends for their vehicles because engines are built to far tighter tolerances than they used to be. Even a small amount of wear is significant and affects power, economy, and emissions.
