1991 liberty engine oil

Is it true that if the wrong engine oil is used that it will cause the engine to run irratically?



false: oil that is fuel fouled will, so engine wear and how it is used ie short trips long trip etc determines how soon the oil will deteriorate

I have now discovered that it is true. I was using oil that was too heavy-20w-50. Having changed to 10w-30 the problem has gone.
