- LBLogan Brewer3 days ago1.0Asked for a synthetic blend was charged for full synthetic, asked for 5w30 got 0w20. Denied the filters and went to replace myself 30 min later and the air filter was jammed in the intake wrong and the cabin filter door wasn’t securely replaced. Id recommend taking your car somewhere else for service. Theres cheaper places that will pay better attention to details rather than rushing through the work.
