It's a common thing in adults. More so than most think. My son is 30 now and had a bad case of it. I was serious when I said that, I wasn't making fun. I have a lot of experience with it and can spot it quickly.
With that said, don't let these yahoos veer you off track. You may have a small overheating issue, but it's certainly not enough to warrant changing oil grades. Were you running 900 plus HP in a big block with LOTS of heat buildup, then you might would want to look for every avenue to help run cooler. You're not.
