So a Facebook friend just posted a picture of his odometer with 555,555 on it. He's taken a pic of every milestone (111,111; 222,222; etc...) Looking through the comments, he replaced the transmission at 510,000 miles. Since I have the same drivetrain in my CR-V I asked "What oil/what weight? Did you do regular drain and fills of the trans before it needed to be replaced and if so, was it Honda fluid or another brand? I have the same K24 and likely the same trans in my CR-V. Mine will rust away long before 500,000 but inquiring minds would love to know. Thanks."
His reply: " I believe it’s a 5W-30 synthetic blend (like Valvoline’s MaxLife or something along those lines). Hadn’t really done much with the transmission fluids; in retrospect I should have done more."
Wow, just wow. If he's remembering correctly, that's a Honda automatic that lasted 510,000 miles without any (or very few) drain and fills. Further convinces me that I overthink things when it comes to vehicle maintenance. Anyway, just thought I'd share a high-mileage vehicle story.
