Best Motor Oils for Cars: Top Picks and Expert Recommendations



While electric vehicles are becoming a gradual rage, you can’t ignore the fact that internal combustion engines have still a long way to go. And millions of people will still drive cars with internal combustion engines as long as they are allowed to move on the roads. For such people, the engines of their cars need to be as much healthy as possible, which is where good quality motor oil plays a significant role. Following are some of the best motor oils one can buy in the USA for cars with internal combustion engines:

Mobil 1 Extended Performance

If you want the best of all worlds, the Mobil 1 Extended Performance full synthetic motor oil is a highly recommendable option. Capable of protecting the prime components of an engine for a year of up to 20,000 miles, this motor oil comes with additives for protecting against sludge and deposits. It also comes with an oxidation-controlling additive for the prevention of the breakdown of oil.

The Mobil 1 Extended Performance full synthetic motor oil has been acclaimed by American Petroleum Institute and International Lubricant Specification Advisory Committee GF-6A licenses for low-speed pre-ignition. From compact-sized daily drivers to full-blown sports cars, this motor oil is compatible with all gas-powered engines. Some buyers have reported burning this oil quickly. However, most of them are very much satisfied with the durability and affordability of the Mobil 1 Extended Performance full-synthetic oil.

Castrol GTX Magnatec

For those who are seeking an affordable engine oil which is light on pocket yet efficient at its best, the Castrol GTX Magnatec is one engine oil which they shouldn’t ignore. Awarded as the best budget oil, the Castrol GTX Magnatec claims to offer six times better protection than the current industry standards. This claim is backed by Sequence IVA tests used for measuring common wear of engine components. Available in viscosity grades of 0W-20, 5W-20 and 5W-30, the Castrol GTX Magnatec is compatible with all the modern and previous-generation engines of mass-oriented cars.

Throughout its life cycle, this engine oil performs efficiently with its additive molecules clinging to engine components. It results in reduced wear and tear of components, even during idling and stop-and-go traffic. The Castrol GTX Magnatec is efficient in its performance even at temperatures as low as minus 49 degrees Celsius. However, some people have reported that its thickness is higher than expected at lower temperatures.

Shell Rotella T6

Perfectly suitable for all kinds of diesel engines engineered for passenger vehicles, the Shell Rotella T6 is one engine oil which is formulated exclusively for heavy-duty powertrains. Compared to 15W-40 engine oils, the Shell Rotella T6 claims to enhance the fuel efficiency of the diesel engine by up to 1.5 per cent.

Also, when compared to previous-generation lubricants for diesel engines, the Shell Rotella T6 has improved wear protection, as the additives in it provide added protection against dirt and other contaminants. This engine oil helps the engine in low ash formulation, which helps in achieving cleaner emission levels and better heat resistance, thus preventing oil breakdowns and viscosity loss.

Pennzoil Ultra Platinum

If you are someone who intends to take a stand for making this environment cleaner, the Pennzoil Ultra Platinum is one engine to which you should pay attention. Most of the engine oils are derived from crude oils through a process depleting mother nature. However, Pennzoil Ultra Platinum is formulated using natural gas, which makes it much more carbon-neutral.

While the Pennzoil Ultra Platinum is exclusively designed for high-performance engines like the Hemi V8s of the Dodge and Jeep families, it is suitable even for compact engines. Besides this, it also claims to enhance the fuel efficiency figures and clean pistons better than the current range of engine oils derived from crude oils. However, while it is a highly efficient motor oil for cars in the US, it is also one of the most expensive oils to buy.
