Just refer to Mobil's line of miles-specific formulas. 5000/7500/15000. A decent dino can go 7500 miles without a hair of concern. If you doubt it, Audi has been recommending 7500 in V6s and non-turbos back 3 or 4 generations of DINO oil specs and formulations. (SH, SJ, SL, SM) Still think 5000 is necessary for a clean engine? Check out Mori's Audi V6 after 122k on Syntec 5w-50 at TEN THOUSAND mile intervals. Sunglasses, anyone?

That's probably true, I just can't go longer than 5K. I feel bad or weird about it.

No sludge issues?

shadyraven

why not filter and oil every 5K?

Tgr_Clw

I do every 5k

Matt Devo

none, though I did an auto-rx treatment at 90k to be safe

Filter is a nearly useless appendage. Very, very common service practice in Europe.

I still do my own oil changes every 5k miles anyway.

Avantadrive_Original

maybe so but why even take the risk, however small? is changing the oil that difficult for anyone?

The best way to determine the optimal mileage for an oil change is to get your dirty engine oil analysised. Its 40 bucks.
