1951 model 200 with 288ci engine. Is it ok to use 10-30 multigrade oil or do I need to stay with 30 weight for summer?

15W-40 Shell Rotella should suit your needs year 'round.

Thanks for the advice. We talked about it as the service station. One of the grease monkeys who owns a 50 Chevy PU agreed with you as that's what he uses. I have had a problem greasing the front end, but they were able to push in new grease with their phnemantic gun. Steers much better. Every little thing adds to a more dependable car.
