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 ...

To my knowledge, there are not any motor oil brands, types, or weights that cannot be mixed. And I've mixed my share of motor oils...more than I can count.
