PC-12 Quote From A Shell Rotella® Technical Expert
"A high quality additive package can help diesel engine oil to enhance fuel economy, prevent deposits, and maintain proper flow and viscosity in both hot and cold temperatures. This is important with the increased use of SAE 5W-30, 10W-30, 5W-40, and even SAE 0W-40 for extreme cold. At Shell Lubricants, we test all of our diesel engine oils in harsh on and off highway conditions to perfect our additive packages and prove their durability."
