Do I use the same oil and coolant once once I turbo my car?
What's the oil to use? 5W-30, 10W-30 Any specific brand? What kind of coolant?

Thanks!

 

Go with Mobil One 15W-50. It provides the best protection with the high heat of a turbocharged engine. It will also flow down to temperatures of -38F/-39C. Doesn't seem like it would work in that type of cold, but it says right on the back label!
