Owners of America’s favorite sportscar were able to pick the brains of Corvette Mechanics' (thecorvettemechanic.com) Paul Koerner and Brittany George during their seminars presented at the third annual “Corvettes in the D” event, which featured hundreds of cars along the Detroit River last month.
In informative forums throughout the day, Koerner (a GM world-class certified technician) and certified technician George discussed Corvette technology, products and care, and answered questions from event participants.
Koerner talked about the recent evolution of Corvette batteries, including absorbent glass-mat technology, lowered weight and reserve capacity. He also answered questions about vehicle storage and battery life.
“It’s always important to give your battery a visual inspection after any extended length of storage,” Koerner said. “Any white powder residue on the battery top is a sign of trouble to come. There is a battery maintenance option, available for about $100, to keep your vehicle battery fully charged in the event you don’t want to disconnect it.”
Audience members participated in an animated discussion of fuels and fuel treatment options. “The best advice I can offer any Corvette owner is to always use a top-tier fuel,” Koerner said. “They keep the engine clean with better detergency, and they improve responsiveness – especially with acceleration.”
He suggested that owners visit the website www.toptiergas.com for more information on fuels.
One Corvette enthusiast asked if a store like Costco, with its fast inventory turnover, would ensure a fresher fuel. “Good point,” Koerner replied. “Yes, the freshness is important to consider.” Another audience member recommended Shell stations as a top-tier fuel supplier.
For those Corvette owners who have not been regular users of top-tier fuel, Koerner suggested the use of Techron Fuel System Treatment PLUS every 3,000 miles.
“Use a 20-ounce bottle to a full tank,” Koerner said, “and please make sure it is the ‘PLUS.’ That is what’s recommended by GM in their general maintenance guidelines, and is good insurance against sulphur contamination. We want to keep carbon deposits as low as possible, even with fuel injection.”
Koerner warned to “never put C-Foam in your fuel tank, as it is not compatible with fuel level sensors.”
Corvette Mechanics' Brittany George.
George continued with a discussion of tire-pressure monitoring. "With the computerized monitoring, you don't need to use a gauge as often."
An audience member asked if the monitoring was in real time. George explained that “upon ignition, the monitoring does not start in real time. It will actually show the tires’ pressures from the last drive experience. However, after the first few minutes – and after a speed of 15 mph – the system refreshes and is then constantly transmitting.”
George described several conditions in which this monitor could be a valuable safety feature with its ability to forewarn the driver of any air pressure imbalances – especially in racing situations where a blowout could be devastating.

As "Corvettes in the D" spectators left that forum and mingled with the hundreds of Corvettes and their owners, they likely were thinking that, once again, organizers Larry and Verna Courtney, with support of General Motors, Corvette Central, Matick Chevrolet and Michelin Tires, have succeeded with another top-tier event.
