Last time we checked in on the reportedly fussy Corvette Z06 engine, it was leaking vital fluids after Fox News reporter Gary Gastelu took it to the track.
Now it appears that Chevrolet has a fix for at least one of the Z06’s reported engine problems: change the oil, stat.
According to a General Motors spokesman, the catastrophic engine failures all seem to have three things in common: early production builds, oil contamination and low miles (under 2,000).
According to Chevrolet, contaminants in the oil can cycle through the engine during break-in, causing all sorts of fun for owners. (We haven’t heard official word from some owners as to what exactly went wrong, but we’re efforting.)
On its own, Chevrolet said that it was upgrading its manufacturing process to minimize the risk of contaminating the oil. The cause could be thread shavings for the oil filter which may have made their way into the oil pan when the threads were tapped.
As a result, Chevrolet is asking owners to ditch the break-in oil quickly.
“We now encourage all owners to change their oil at 500 miles to remove possible contaminants created during the engine break-in process. And, as always, we encourage the use of Mobil 1 synthetic oil – which is a factory fill for all Z06 models, and Stingray Z51 models – and encourage owners to follow the engine break-in process detailed in the owner’s manual,” stated Monte Doran, spokesman for Chevrolet.
Owners are still reporting heat soak issues and intermittent power steering problems.
Chevrolet says less than one percent of the 9,000 Z06 models on the road have had engine troubles.
