BS.
Asking if you're referring to gas engines vs. diesel. Reason I ask is, wife's previous car (Jetta TDI) recommended specific oils and changes at 10K., which we followed. Never had an issue, but again this was a diesel.

Change it every 7500 miles.
Oil is cheap compared to the cost of a new engine.
Got that right sir.. My current truck (F-350 6.7 PSD) recommends 7500 mile intervals - or 5000 if used for heavy service/towing etc.. I send in an oil change sample every time I change it for analysis and to date it comes back and sez I can go to 10K if I want because the oil condition is so good.. (Mobil-1 diesel synthetic).. Your thoughts on that?

Like you, I'd rather change early for the exact same reason; oil is tons cheaper than an engine..
