Thinking of using it as AutoRx rinsing oil, as I have difficulty finding other recommended oils.
Thanks.
Does Havoline 5w30 have any ester in it?

AFAIK, no conventional oil has esters in it, only synthetics or the high mileage versions. Esters are expensive so it's not likely you'll find them in a $1 quart of oil.
