I was too late to stop her, she igmored me when I told her to bring in, she just kept running the heck out of it. Six months later she had close to 10k 9,942 miles to be exact. My daughter has run this 2005 Civic on PP 5w-20 since new, only because I always buy it and change it mostly, first oil change was at 7k+ miles. I know PP is very good oil but 10k? I should sign her up on BITOG, but she has better things to do at age 20. Anyone run this oil this long very often? Oh I changed it to Mobil 1 5w-30 EP and a pro-select over sized filter, because I ran out of BOGO PP. I placed a sticker to come and change it at 10k, so I'm sure it will stretch out beyond that, at least its engineered to go 15k vs 4k.
