Help guys. My new Kona has 17k on it and will need an oil change soon. I've run PUP 5w-30 and over the winter PUP 5w-20. I didn't really notice a difference in fuel economy. The weather's warming up and I don't know what to use now. The owners manual recommends 5w-20 and it also says something or other that you can use 5w-30 "If u want to" or whatever. So what do you guys think? The car really doesn't seem to care. Is the 30 going to protect the engine better or will the 20 be able to squeeze into tight clearances better and reduce wear? Another question I was wondering about... Would it be a good idea to go straight to a "high mileage" oil? I mean, the way I understand it, the high mileage oils have more of the "good" anti-wear additives because they feel like the catalytic converter is about out of warranty so it doesn't matter... but to whom? Also I've been running PUP but its hard to find and PP is readily available. Is there really a difference? So 5w-30 or 20... PUP or PP... regular or "high mileage?" ...anybody know how long Amazon is taking to deliver a jug of oil right now?
