We currently have 184,000 miles on our 2013 sonic with the 1.4 turbo! It’s used on a gravel mail route! The biggest issue we’ve had is the water pump, 3 so far! Never any internal engine problems! I’ve consistently used 1 quart of Dura Lube engine treatment in 3000 miles oil changes! Any comments good or bad on Dura Lube?? I use it in all my vehicles and have never had internal problems!
