I am glad my dad and brother are mechanics.
He told me to never take my car to a Jiffy Lube, Valvoline, and other shops like that. They usually hire people who have no idea what they are doing. A family friend took their car to Jiffy Lube once and they forgot to put the oil plug back in when they were done. So, the engine locked up and Jiffy Lube said they didn't do it
Bottom line, either do it yourself or take it to an independent mechanic.
