GDI, or Gas Direct Injection engines, are great engines and have a lot of benefits. But because of their design, these engines have some maintenance requirements that non-GDI engines do not have. 1) In order to reduce frictional drag energy loss and increase fuel efficiency, GDI engines use thinner and lighter piston rings, called low tension piston rings. With time varnish builds up behind the rings causing the rings not to seal as designed. 2) In traditional fuel injection engines, the gasoline washes over the valves cleaning them in the process. In GDI engines gasoline is injected directly into the cylinder, so it never comes in contact with the intake valves. Without that constant cleaning action, harmful carbon deposits buildup on the valves.
We offer and recommend every 2-3 oil changes, two different services to address both of these maintenance concerns.
