I run a shop and use Standard products on a regular basis, and they damn sure ain't what they used to be. Failures NOT uncommon. Yeah, they came out recently with Blue Streak again, supposed to be "better". Keep in mind that Standard offers two series of products, and their lower line is junk, IMO. Lower line has an S at end of part number (or maybe a T, don't remember because I refuse to use them. Either way, just make sure part number does not end with a letter). If you buy from O'Reilly's, you can be sure it is top line, as they don't offer lower line.
