90,000 on engine that has been pulled apart to check bearings/torque and a full gasket set repair as well as new oil pump water pump etc.. I bought 20-50 vr1 racing oil is that not a good idea to run right away? Should I run 5w30 something lighter? I wont go back to synthetic oil again on a older engine, I have a feeling that's what went wrong with my other engine because of the mileage. I plan on running the oil for about 50 miles then change it again or is any of this not needed?
Thanks for your help always much appreciated.
