Generally speaking....is there really a big difference in startup protection between 5/30 and 10/30?
From what I can gather....5w is around -45F and 10w is about -39F. Both of those temps are well below anything we see around here. We see single digit temps here and there. But our winters are generally teens to low 30s at night.
If I used a 10w oil would I be giving up enough protection to warrant any concern?
