We do not have to demonize corn syrup and mayonnaise. Fructose corn and eggs are both very good fuels for the human body to consume depending on the demands. We may view at high fructose corn syrup as the 93 octane gasoline we cannot afford to put in our car. Mayonnaise is like the thicker grade motor oil. Sure sometimes they're bad especially in excess, but many times it’s good to change the octane of the fuel and viscosity of the oil. Our conditions change. Are we too stagnant or too conservative? Do we listen? We “perform” how we eat. Enjoy the good stuff and check with your doctor.

From Texaco:
Thus, a typical 5W-30 motor oil has the same approximate kinematic viscosity as a SAE 30 grade oil at 100 ° C, but it's viscosity at very low temperatures, while thicker than when hot, is much less than the 30 grade. This is achieved by formulating multigrades with a higher Viscosity Index than typical for single grades. So, while a 5W-30 oil will allow a modern car to start at temperatures as low as -30 ° C, the typical SAE 30 oil would be too thick to either crank or pump at that temperature.
