If you're in the market for a new car, the chances are very, very good that its manufacturer will recommend a synthetic (or at the very least a synthetic-blend) motor oil. The reason automakers are increasingly turning to synthetic motor oil in their cars are many, but for most vehicle manufacturers it comes down to one simple fact: fuel mileage.
You see, synthetic motor oil--especially very thin grades like 5w20 or the 0w20 now recommended in most new Honda and Toyota vehicles--not only protects better than conventional motor oil, it can also provide a small but significant boost in fuel economy.
So, imagine you're a car manufacturer tasked to meet ever-tighter fuel economy regulations. Even a small 1-2 percent boost in fuel economy achieved via the use of synthetic motor oil is significant when multiplied by the millions of vehicles you sell.
True, synthetic motor oil costs a little more than the stuff you've been using during your time behind the wheel, but over the long haul its benefits greatly outweigh its increased cost.
