Others are for less frequent drivers and still more are designed for harder long term use. The best type of oil you can buy that is also the longest-lasting is synthetic oil. These products are specifically designed and produced from chemically modified petroleum products with additives to help reduce engine wear.

Using a synthetic oil means your vehicle gets better startup performance as well as better oil flow in the engine, even in cold temperatures. It also stands up to very hot temperatures without turning black and oxidizing. Many vehicle manufacturers are moving to use low viscosity oils to reduce the friction in a running engine and synthetic oils do just that. They have a lower viscosity than conventional oils and hold their lubricating properties longer, especially in extreme conditions.

They track the length of your car trip, engine temperature, and other engine specifications and use internal logarithms that use these variables to calculate and let you know when it’s time to have your synthetic oil changed.

In contrast, if your vehicle is older then you can find oil for it, tool. There are synthetics called “high mileage oil”. Valvoline makes a good synthetic high mileage oil. These particular oils have additives that are good for older engines with more miles on them.
