the previous owner looks it at it and says it is running low on oil (oil hose for turbo blew and oil drained out)

i put 4 qts. castrol 10w30.


Please tell me you drained the rest of the oil out first. That being said, there is no drain (that I remember), you have to drop the tank out of the car. Gas starts turning to varnish after 30 days. After three years you're lucky it ran at all.
