dont have a Pep Boys around me, so didn't bother to look at the ad, would do me no good. lol
but yeah, if they have the right weight, go for it.
I know oil can be a hot button topic, but my nickle's worth is this.. better to keep the oil level full, even with mediocre oil, than to let it run low.
the 90 Legacy i had some years ago leaked oil pretty badly when i got it (oil separator plate) so until we had the time to yank the motor and reseal it, i used the cheapest oil i could, just to keep it full. After getting the reseal done, it got better quality oil and it was changed regularly - no ill effects from the cheap stuff - at least not while i was driving it. ended up selling it to kid for parts about a year after I parked it.. he got it started and actually drove it home.
