I ran diesel oil in my '94 yukon for the entirety of it's 260k miles. My dad always said the same. The zinc was better for it. When I got rid of it, it was still running fine and driving fine.

Pros: running fine, driving fine

Mileage: 418429 km

So I took his advice and did the Rotella T-4 and MMO in my 71 LeSabre 350. Added a little to the gas, too. I run 93 octane gas. Engine is stock and original, about 90k miles. It's running so smooth now. It was an immediate, noticeable difference.

Pros: running so smooth

Mileage: 144840 km
