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 ...

If you read the bottle you will see that they are "compatible". If you research you will find that this word was added when synthetic oil cme to be common. It means that all oils, within the same spec can be mixed. It will vary the weight, so if to 6 qts of 5W20 you add 1qt of 10W30 you will end up with 6W22 or close. This was explained to me by one of the engineers of exxon mobile when they were making the pitch to use Mobil 1 in the Dodge Viper as the factory and recommended oil(I used to work at Chrysler at the time)
I have been doing it for 15 years, never had an issue with it. Any weight, synthetic, blend or regular old dyno, as long as the weight is within 10-20%.
