Yes ... and ... no. Engines with lots of miles might be better off with a synthetic oil as synthetics have less friction, and less friction means less heat, and possibly better/longer engine performance. Be careful out there though ... there may be scrupulous people who want to sell you some 'special oil' at a very special (high) price that could be nothing more than normal engine oil. I myself use 100% synthetic oil in my car, and have been since the day I drove it off the car lot when it was new and that was 12 years ago and now nearing 150,000 miles and NO engine wear or problems.
No
It depends on the car make Most of the cars 100,000 miles is a high mileage For some cars as Mercedes, BMW, Volvo 150,000 miles is a high mileage Alaa Farag
Royal purple is whsts used in race cars, full synthetic. 8000 miles between chnges.

All Subaru cars offer really good gas mileage. Any of them would be a great deal. I think they are mostly the same as well, I know they all get greater than 20 miles a gallon.

NO. For a diesel this is very low mileage.
There are tons of mid sized luxury cars and most are not known for high mileage. Some of the top selling luxury cars known for getting the most miles are the Toyota Camry, Cadillac and Nissan.
You might want to check for Toyota's and Honda's with mileage over 100,000 miles. These cars rate very high
30000 miles
When speaking about high gas mileage cars, it is very difficult to not speak about hybrids. Hybrids today rely more on electrical power sources rather than gas power sources. This process then allows the vehicles to reap the benefits on getting high gas mileage. With less and less wear and tear on the vehicle due to how prominent the electric engine has become, some hybrid vehicles can get roughly 100 miles per gallon.
