Going over this new to me car and want to swap all the fluids out. It runs good with 150k miles on the original engine. Would redline 10w40 be a better choice over the 10w30 on something with this kind of mileage? I just figure bearing clearances maybe gained a 0.0001 or 2 with mileage and with older valve stem seals etc maybe it wouldn’t hurt? I would just like an overkill oil to keep from spinning a bearing.
