I compared the Microgard Select to the STP XL for my vehicle. They looked very similar in construction, but the MGS was made in Vietnam and the STP XL was made in China for that specific filter model. I'd probably run either one. The STP was $1.00 less.I don't like Orielly but it looks like the Autozone STP XL's which I do like. Maybe they are the same just different label?
