The simple answer is that you usually can't. If it's not in your owners manual, and you don't feel like consulting a Haynes/Chiltons manual, you can do some quick 'net research on your particular model AND TRIM LEVEL of your car. Actually, you CAN do it, but it's not really worthwhile and usually involves using the VIN to get info you probably could have gotten easier than searching for a vehicle-specific VIN decoder. If you insist on doing it through the VIN, you should know that the 8th digit is for DOMESTIC vehicles, and only since '81. Unless it's a Hummer; they use the 4th digit. True, SOME imports use the 8th digit, but not all. The 4th-8th digits are reserved for model-specific info... which may or may not include actual engine identification! Using the VIN is a difficult/convoluted way to find your displacement unless you truly don't know the model and trim level of your vehicle. I didn't need a VIN decoder to find, with a few minutes research, that my Honda had a 1590cc engine. Maybe these will help if you insist on using the VIN, but honestly, there are easier ways. http://www.analogx.com/contents/vinview.htm http://www.amsoil.com/products/vin_code_lookup.pdf

The 8th digit in the VIN tells what engine was put in the car.

The 8th VIN number does tell the engine size in all American and most foriegn cars.

The 8th digit of the VIN tells you what engine is in your vehicle. What kind of vehicle do you have anyways?
