91,000 miles and all seems well

[Piersol]

Just got my oil report back and at 91,275 miles the numbers look good. Al-3; Ch-1; Fe-10; Cu-1; Pb-1; Fuel %-<. 5; Insolubles . 2 I use Rotella T 15W40 and change it every 4500- 5000 miles. Tempting to buy new with the low financing and 100,000 warranty but I'll stick with what I got. At least to 200,000 miles.

After driving a trouble free 12 valve moving to a 24 will be a step down. Keep your 12er till it falls apart.

140k and counting. My last one went to 196k before I sold it. It ran the same as it did when I bought it at 112k.
