Yet you only need to look to the US for reassurance, where 100,000 miles is seen as the baseline and cars are kept for decades with hundreds and hundreds of thousands of miles accumulated. You needn’t worry about high mileage in many cases – but there are certainly some things to think about.

Does a oil change make a difference?

Changing your oil offers a lot of noticeable benefits, as well. Regular oil changes improve your car’s gas mileage.

How often should you change your engine oil?

There is a permanent thickening of the oil. Some automotive manufacturers are backing down on oil change intervals to 5,000 miles or less and some advocate changing the oil at least every 6 months as well. I think this is because of the tendency for oils to thicken in very hot engines (not ambient conditions, just hot engines).

Do dealerships charge more for oil changes?

Interestingly, one of the primary benefits most people consider — that dealerships charge more for oil changes — isn’t always true.

Oil quality and viscosity: When oil is thicker (i.e: more viscous) it faces more resistance when passing through the engine’s passages, leading to higher oil pressure. Changing the viscosity grade to a thicker or thinner oil has an effect on the oil pressure.

Is oil pressure too low or too high?

Oil pressure is necessary for oils to outstretch all the components of an engine. Oil pressure may vary from vehicles to vehicles depending on the engine system. However, it is considered too low or too high when the pressure remains elsewhere of the required range, 25-65 PSI.
