OEM for sure....as good as it gets, zero problems, not overpriced at all (It's a Chevy!). I change mine automatically every 6 months. Why risk a 70K car with lousy vision at night in the rain, just to save a few bucks a year? That's lunacy!
I've never used mine except to test them to see if they work.Should I replace them on A regular basis anyway?
Yes, they will dry out in time. Get brittle and not work properly, causing streaks and smears the mud on the windshield. Of course the worse streak will be in the drivers view...Murphy's Law. I do mine once a year on my 3 cars.
Years ago, I bought a set of silicone, single edge wiper blades. They worked very well and lasted a long time. Probably too long for the manufacturers's liking because I never saw them for sale again. Their durability was significantly better than traditional rubber blades, IME.
Anyway, seems like the OE blades work quite well. I'll likely replace with the same. I haven't tried a ton of aftermarket blades, but those I have really haven't worked any better or lasted longer than good OE blades.
Valero - last about 5 years - not cheap good aero for higher speed driving and using the wipers. Put one on my Lotus within a month after that I put them on all my cars.
This is my first GM car, so I can't comment on the OEM wiper blades, but I used Michelin's on a couple of other cars and they worked much better than the OEM ones, even new OEM ones. (Once had a dealer take off my almost new Michelins and replace them with OEM wipers, unasked for. The brand new ones were worse than the slightly used Michelins. I was not a happy camper.)
Haven't used OEMs on my Vettes yet but when I had my 08 Malibu I found a windshield wiper comparison test which rated the Valeo's as the best performing wipers. Then I found out the Bu wipers were made by Valeo. Got my Corvette Club discount at the local dealer and had a brand new set of Valeo's for half of what a set of Bosch Icons had cost me before.
Planning on doing the same for the new Vette when it is time for new blades.
