I have been doing it for at least 15 yrs now. At one time synthetic was expensive. no more.
I would always make sure there was at least 1 qt of synth in my car, because it will save your engine, should it run dry for any reason.


walmart sells 5 qts of synth for a little over 15. at this point and it is a moot point, if worried about cost.


I run it in my lawn tractor, A's and all cars and vehicles. nothing better.
