Time for the high mileage oil?

[Cerwin Vega Fan]

My LT1 is currently around 77K and when I have my next oil change the car will just be hitting 80K. I run nothing but Castrol 10w-30 in my car but I was wondering if it was worth changing to those oils that say they are made for engines with over 75K miles. I mean what do these other oils do that is different from regular oil?

im not familiare with 'oils made for high mileage engines"..other than goopy gunk like STP that does not live up to what it should....

just keep your oil changed often with a high grade oil. i use Mobil 1 in all ours.... and will continue to do so regardless of mileage.
