I hear you on that one, wearing amplification helps but high frequency sounds like squeaks valve clatter is unobtainable and really does impair your life. It’s the same with eyesight but at least readers help or task glasses. This getting old is for the birds.
To make it a legal post, I change the oil in my subie IM every 3k with new filter. I have been using Penzoil full synthetic 5w30 pretty much since I got it. My subie tech guys uses 5w40 Gulf FSyn and suggested for subies it helps with oil consumption I may give it a try.
All my DD at their recommended intervals or yearly. The only vehicle that got done at the dealer was my Odyssey it was so cheap but the price recently doubled with this last prison sentence
