Went to O'Reilly's Auto Parts to check out these two part numbers. The MGL is the basic filter while the MSL is the 10,000 mile extended filter.
Almost 99% positive the basic MGL is a WIX 58706 (One on right with the green oring). I was told a while back by Premium Guard that some of the O'Reilly's basic Microgard branded filters are still WIX and this seems to be a classic case of that.
MGL58706 (Made in Vietnam) Comes with Silicon Oring
MSL58706 (Made in China) Green Oring (China seems to prefer Green on darn near everything
)
Both filters appeared to be 100% flawless.
