My question- do you have to use semi synthetic oil in a this engine? My dealer has said that you have to use synthetic oil or the check engine light will come on and stay on. My book doesn't say anything about using a synthetic oil just 5w20. Who do I believe the dealer or manufacturer? Is my dealer trying to rip me off?
have the same problem?
