Your luxury car's engine is built to the highest standards and it requires oil that meets those same standards. That means a very specific industry and automaker specifications that ensures a long service life for your beloved automobile.
And did you know that when you don't use the right oil for your car you could even void your warranty?
Most gasoline engine luxury cars need a synthetic-blend or full-synthetic, low-viscosity, multi-grade, resource-conserving oil.
These types of oils minimize friction and maximize fuel economy. However, choosing the right oil is not always easy.
But there's another important consideration: When to change the oil.
If you drive an older luxury car the owner's manual will likely tell you that its oil change interval is based on its mileage. There are usually two maintenance schedules - one for cars driven in "normal" operation and another for those used more and under more rigorous conditions.
But most newer luxury cars are equipped with an oil-life monitoring system that automatically determines when an oil change is needed. You will then be notified with an alert on your car's instrument panel.
Those earlier systems were mainly mileage-based, but advanced systems on your newer luxury car analyze your vehicle's operations and tell you when the oil will begin to degrade into something that is not as good for your car.
That so-called "oil-life monitoring system" automatically shortens the oil change interval when it detects heavy-duty operation. So there is no need for the old "severe service" criteria in manuals of older cars. How cool is that?
Some other points to keep in mind when it comes to changing your oil:
Whenever you have your car's oil changed, the technician should reset the oil-life monitoring system.
Changing your own oil? You can reset the system yourself by following the instructions in the vehicle owner's manual.
Those less frequent oil changes on newer engines make it essential that you check the oil level monthly and top it off as needed.
Keep in mind that while many engines will use less than a quart of oil between changes, others can consume as much as a quart every 600 miles or so.
Maintaining proper oil levels will help you avoid blowing your engine and enduring expensive car repairs. This is especially important because engine wear or damage resulting from low oil levels will not be covered by your warranty.
Even if you don't put many miles on your car, most automakers recommend an oil change every year even if the maintenance reminder has not been displayed.
If your car is older, here are some other signs that you might need to have your oil changed:
- Excess Vehicle Exhaust.
- Falling Oil Level.
- Increased Engine Noise.
- Irregular Oil Texture.
- Low Oil Level.
- More Mileage Than Usual.
- Persistent Check Engine Light.
- Shaking While Idling.
