Is it a good idea to move from Synthetic oil to normal oil ?

Oh for God sake not another oil post! Make it stop! Listen, it's a little generic rusted out old sh1t box of a car. Put whatever oil you have into it and it will run for 400K miles. I mean seriously, if you're are using royal purple every 3k miles in your Yaris, you're flushing money down the toilet. There isn't s Rolls Merlin under the hood. If its liquid, made out of something with lubricity and has a flash point over 300F, dump it in and drive. At the end of the day who gives a f@ck?
