Mixing oil types (5w-20 mixed with 10w-30)
My RV has the ford v-10 in it and I noticed today the oil is closer to the "low" level than the "full" level on the dip stick. I have a few quarts of 10w-30 (might be 5w-30) but I was going to top it ...

My 5.4 has run the last 100,000 miles on 5w30 instead of 5w20. Mix them? No issues.
I would far rather have slightly wrong viscosity to being a quart+ low on oil any day.
