I will not be driving or starting my car for 4 to 6 months. I had the oil changed 3000 miles ago in Jan 2019. Should I change the oil again now or wait until I will be using again 4 to 6 months from now. I know that changing it both now and later would be best, but which would be best with rational economy in mind.
Just speaking for myself I would wait until return for the oil change but I would put fuel stabilizer in the fuel tank . Not sure what rational economy means .
I’m not sure either what rational economy is, but it was the best description I could think of to also consider cost vs outcome.
