That would be the case if there weren't such things as temperature extremes. Ever see dino oil at -20F? You may as well not have any oil in your engine at all. You can't honestly say that doesn't affect the wear on your engine. Synthetics (and some blends) will flow very well at -20 and below...that is just one of the many benefits. In one year, I spend $66 on oil and filters (2 filters, 7 qts oil)...and that's 24k miles. Change your oil every 3k, and you'll go through 7 additional oil changes (42 qts oil, 7 filters) for a total of around $84. Then add the price of labor for each change. I change my own oil, and my time is worth something. Yours may not...that's for you to decide.
Now tell me.....How is dino oil cheaper?
