Hello everyone. Im a newly registered user and recently purchased a 2002 Lincoln LSE. I took it for an oil change today and the service tech dumped the required 6 quarts of oil into it and the stick still read a quart low. He then proceeded to add another quart which made it read full. Can anyone tell me if this is normal. I know it has an oil cooler, so would that explain the extra quart needed? Thanks.
