Oil sludge is a common problem with many 2002 Dodge Ram 1500 vehicles. 

Many owners report that the engine has failed due to oil sludge. 

Problems usually start with a drop in oil pressure and an engine misfire.

Are 16-inch wheels better than 17-inch?

Quick reply. The larger 17-inch alloy wheels give the car sporty handling by 

improving cornering and stability compared to 16-inch wheels. However, 

16-inch wheels are cheaper than 17-inch wheels, 

have less road noise, save fuel, and feel comfortable.
