Like heck it is! The difference between a 3,000 mile interval and a 5,000 mile interval (which are both EXCESSIVE for a diesel) amounts to 40 additional oil changes at 300,000 miles, or about $8,000.

Push it to 7,500 miles, and you are over $12,000.

I'll spend $80 for an oil analysis a couple of times to save $12,000.



Well 300,000 miles for me is 15-20yrs. Think whatever you like, do whatever you like.....makes no difference to me. Ten quarts of Rotella @ $12/gallon to me is cheap insurance for a $30,000 engine. You agree or not, so what.
