Just wondering on the 10-40 10-30 or 15-40? Please explain why one is better then the other? Not doubting at all, I know these are suppose to have 10-30 in them, but I always run the 10-40 because of the higher miles you know a little thicker oil.
Will the 10-30 or 15-40 help with the bearing noise on start up? Thank for all you help, I will get it changed out asap, just need to know what would be better in it of the two choices? Thanks
