My car is suburu Forester 2012. I usually change the oil in the car between 7000-10000 miles. On Jan 13-2016, at 71854 mile, amsoil 5 quart synthetic oil was placed at oil change. On Aug 8th at 80600, I went in for oil change and also the car was making knocking sound. The suburu dealer told me engine seized due to lack of oil in the engine. The car was deemed not drivable. There were no evidence of oil leak under the car or around the oil container on the engine, when check by the glassman dealer in southfield michigan. Suburu Forester does not have any engine oil level light. The engine consumes the oil and, the owners should be warned about this. I lost 6000. 00 money on the trade in due to the engine condition.
