What is WT in truck?
What is WT in truck? WT stands for work truck and the Silverado 2500HD WT comes well-equipped. What kind of engine does a Chevy Silverado have? The 4.8- and 5.3-liter V8 engines offers improved fuel economy through new variable valve timing, while the 5.3-liter versions get a taller 3.08 axle ratio and fuel-saver mode, along with a 6-speed automatic transmission, to increase EPA ratings. All three engines now have E85 Flex Fuel capability. What kind of gas should I use for a Silverado Sierra? Truck is a '09 Silverado with the 5.3L. Thanks in advance.
