Except its for Diesel Engines !
Shell Rotella 4 Triple Protection® oils use a proprietary formula exclusive to Shell. They are designed to protect under the most severe engine conditions found in modern low-emission and older, hard working diesel engines
Shell Rotella T4 NG Plus 15W-40 meets the specifications for natural gas, diesel and gasoline engines, making it a true multi-vehicle engine oil.
Gasoline combustion creates different by-products than diesel. They may not be removed by the diesel engine additives. Diesel oils are designed to keep soot particle in suspension to be removed by the filter. I don't know if this could be a problem or not long term. I would use a gasoline rate oil (API) or the one above that built for both. Just my opinion. Shell Rotella is a well known proven product.
All modern day oils keep particles suspended. The additives are specifically engineered to clean and keep engines clean.
Rotella is great due to zinc content for flat tappet motors as well.
