How can you tell if a car you recently bought has synthetic motor oil in it?

You really can't without having the oil analyzed. More expense than it's worth. Unless the oil is so fresh that it isn't dirty looking yet, change it and the oil filter right now. If the oil is THAT fresh, all nice and clear colored, suspect that the seller had some reason for changing the oil just before he let you look at the car.

Some store-bought cotton balls are made 100% from plants, while others are synthetic. Read the fine print on the package label to tell them apart.

You cannot tell by looking at the oil. Owners manual will tell you. You can use synthetic even if it came with conventional. But if the manufacture recommends synthetic then by all means use it.

You would have to actually look at the car the engine came out of or trust the salvage yard to tell you the true mileage.
