is that true? Using dino oil on new engines?

I think you can just go with synthetic now of these days, I know Demon did with his new engine. . . .


Actually my engine already had 4k miles on it. The rings were already broken in.

I added clevite rod bearings and ran dino oil (Mobil 5W30) for the first 500 miles.
Mainly to give a thorough cleaning of any FO that entered the disassembled engine and any excess bearing silt from break in.

I then switched to Mobil 1 0W40.

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
