You are awesome. I had a soft spot in my heart for Valvoline, but I have heard that it is a sort of a lackluster oil, and from what you've said about their TBNs lacking after a short time and the UOAs, I think I sadly will stay away from them. I still think it's a great oil, but I think there are slightly better ones.
I try not to let emotion control me, but of course it still does. I can understand the emotional connection one might have with a car, that listless nostalgia, that indecipherable, unknowable sense of longing and bittersweetness that comes from some beloved car. And oh how utterly worthless that all is. It's a car. It's a thing. And I don't want to love things, these worthless things. I love that Sprint Turbo because it is incredible on gas, and it was affordable. I believe in straightforwardness and honesty and practicality and earnestness and I can't find the word. Something so pure and honest and strong and basic that cuts straight from your core about it. Of necessity. Of usefulness. Of purity.
I just looked at some Napa Synthetic UOAs and they were disappointing to be honest. I think I won't be trying it. I guess I still haven't found my favorite oil yet. It would be AMSOIL if it were cheaper. I'm sort of looking into Pennzoil Platinum. I think I'd feel comfortable going 9,000 miles with PP. It may be my favorite, but I'd love to find some cheap, off-brand awesome synthetic oil. Napa Synthetic seemed like a sleeper to me, being so cheap and with it looking a lot like Royal Purple on paper. But it seems more like a 7,500 mile oil instead of a 10,000+ oil like PP. Of course, it all depends on conditions, but just average in general. One day there will be an oil that you won't have to change ever. Maybe. Hopefully. Lol.
What is OTS Synthetic? I tried looking up the abbrevation here:

What's the advantage of running 5W-30 instead of the recommended 10W-30? I guess I could look that up myself, but last time I tried to read something on oil viscosities, it was much too complicated for me. That does interest me, and I am curious as to the different viscosities and the potential pros and cons.
Yeah that's the good and interesting thing about air filters. It makes sense. New, it flows a lot of air, more than needed, and as dirt accumulates, it kind of levels out gracefully. Changing air filters more often than needed is almost just as horrifying as changing your fully synthetic oils every 3,000 miles. Absolutely unnecessary in the highest sense of the word. Lol, might as well throw out half the food in the fridge for no good reason. That's kind of the same thing, lol.
