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 ...

The same question applies to engine thermostats. In the old days people would install a higher temperature thermostat to make the cabin heater work better. Now it is just too much trouble to change them. We put cardboard in front of the radiator - often forgetting it and overheating the engine in the spring. There has to be a better way.
Actually they are designed to fail open but no-one notices that... just the stuck closed failures.
Replace with OEM rating.
