Was running 10W40 during the winter and 20W50 during the summer while pulling a 16' vintage trailer. Oil temp stayed low so tried 10w40 year round 10W40. Missed an oil change, yet not problems. This is a 500+ hp 383 10.5 comp AFR heads, 256 degree Howards solid flat tappet cam, Edelbrock tunnel ram and twin 450 Holleys. Shift it at 6500 rpm pretty regular, yet the rockers rarely need adjustment. Oil must be doing it's job.
