Sorry, that would be Delvac 1, 5-40. Why 10K? I had the oil analyzed at 7500K, was good to go. Did it again at 10K and was still good. Just could not go any more. 10K is now my program. I might add I use Balwin filters exclusively.
In addition, I drove a 84 Camaro 280K using Mobil 1. Changed the oil around 10K, no engine issues. Needed a clutch at 120K, traded it when things started falling apart around the running gear.
