| ExxonMobil Sponsor Guinness World Record
| |  | An Australian truck, the “Bandag Bullet” broke the Guinness World Record for diesel truck speed on July 16, 2005, at the Queensland International Air Show, held at the Bundaberg Airport in Australia. ExxonMobil was a sponsor and supplied the engine oil for the world record-breaking effort.
Driven by Frank Gaffiero, the “Bandag Bullet,” a Kenworth T400 truck powered by two V8 Detroit diesel engines, is the only conventionally powered truck to achieve an average speed of 182.152 kilometers per

| hour (113.184 miles per hour) over one kilometer from a standing start.
The "Bandag Bullet," has been recognized by the Guinness World Records (TM) as the World's Fastest Diesel-Powered Truck. Engine temperature during the record-breaking run reached approximately 100 degrees Celsius (300 degrees Fahrenheit) above typical operating conditions. To protect his engine during the run, "Bandag Bullet" driver Frank Gaffiero used Mobil Delvac heavy duty engine oil.
