That's what I'm approaching now!!! I've officially got about 130 miles to go before a "full" 80,000 miles without a complete oil change, but I thought I be pro-active and tell y'all prior!!!!!:cool:I plan on taking an oil sample and sending it to Blackstone for analysis at the next scheduled TP change out. That'll be just over the 80k mark, but close enough. I'll post the results when I get them. Those "butt wipe" filters work well!!!
