I posted before and still don't feel comfortable buying anything yet. I have 2012 Kia Forte ex. It's my girlfriends car. It is making a ticking sound while the engine is running currently im using a fram ultra filter and QSUD 5w30 and it's still noisy. The car specs 5w20 so my plan is to switch to a Kia oem filter to hopefully help the tick as I've read a tsb from Kia saying not to use anything but oem filters so I'm gonna try that. But I also want to know what the best off the shelf oil would be for it? I would like the quietest and just best overall. It gets highway tripped a lot and barely short tripped or city tripped. It's more of our long trip highway vehicle. I've read that QSUD is usually the quietest. Anyone have opinions?
