Shell Royal Dutch Shell produces Rotella, a series of heavy-duty engine lubricating solutions. Engine oils, gear oils, and coolants are all part of the series. The oil is rated “C” for diesel engines and “S” for gasoline engines by the American Petroleum Institute (API). The oil has different ratings. Rotella oils, such as the T3 15W-40, are API CJ-4 and SM compliant and can be used in both gasoline and diesel engines. It is, however, designed for automobiles without catalytic converters and contains phosphorus levels in excess of 600800 ppm. Rotella is therefore not suggested for gasoline vehicles equipped with catalytic converters due to the increased risk of harming these emission controls. API SM has rated newer Rotella T6 formulations as safe for pre-2011 gasoline automobiles.
Is it possible to use 15-40 diesel oil in a gasoline engine?
Yes, diesel oil can be used in a gas engine as long as the diesel oil fits the engine’s specs and viscosity criteria.
If your gas engine requires a 5W-30 motor oil that satisfies the API SN PLUS criteria, for example, you can safely use a diesel oil of the appropriate viscosity that fulfills the API SN PLUS specification.
However, for most gasoline applications, a diesel oil isn’t necessary, and a good gasoline motor oil is a better alternative in terms of performance and cost. Let’s take a closer look at the diesel vs. gasoline dispute.
Is it possible to use Rotella oil in a gas engine?
Shell Rotella is a range of heavy-duty engine lubricating products manufactured by Royal Dutch Shell. Rotella oils must meet both the API CJ-4 and SM requirements, and they can be utilized in both gasoline and diesel engines.

What happens if you run a gas engine with diesel oil?
The fuel pump will struggle to transfer the diesel/gasoline mixture through the system since diesel fuel is thicker and denser than gasoline. Additionally, the diesel will be unable to pass through the fuel filter easily. It will instead clog the fuel filter. And any diesel that makes its way into the engine will block the fuel injectors, rendering them useless. The engine will clog up and seize as a result of this. The gasoline engine may continue to run after the diesel tank has been filled, but this is only because it is still running on the residual gasoline in the fuel line.
As awful as that circumstance would be, putting gasoline into a diesel tank would be much worse. Because of its enormous combustion potential, gasoline would ignite more faster than diesel fuel. The diesel engine and its components could suffer catastrophic damage as a result of the early ignition and volatility.
Is it possible to utilize Rotella T4 in a gas engine?
Shell Rotella T4 NG Plus 15W-40 is a natural gas-powered car oil that has been particularly developed to handle the high heat and give the necessary engine protection.
What’s the distinction between diesel and gasoline oil?
To obtain the desired performance, gasoline and diesel engine oils are created by blending basic oils and additives.
When we look at the lubricant’s required performance for each engine type, however, we start to see some differences.
The Viscosity
One of the most significant lubricant factors is viscosity, which comes to mind when thinking about engine oil. As a result, determining the proper viscosity is critical.
When compared to gas engine oil, diesel engine oil has a higher viscosity and lower temperature pumpability. If it was used in gas engines, several issues might develop, such as heat generation, premature wear & tear, and more.
The Additive Levels
As previously stated, additives are an important component of engine oils. Each engine oil, on the other hand, has a variable level of per volume and various components.
Diesel engine oil has more compounds, allowing it to withstand the high pressures of the engine, but such additives added to gasoline oil might have an adverse effect on the car’s performance, resulting in decreased compression and efficiency.
The Replacement Intervals
With the various types of engine oils on the market, each has a varied suggested lifespan, and diesel oil lasts longer and requires fewer oil changes due to the high quantity of additives.
The Catalytic Converter & Emissions
A catalytic converter is a part of the exhaust system that is located between the engine and the muffler and contains porous metal filler. Its job is to convert hazardous pollutants from the engine into stable byproducts before they enter the atmosphere.
Diesel engine oils have a greater anti-wear level, and diesel catalytic converters are intended to handle it, whereas gasoline catalytic converters are not. As a result, using diesel engine oil in a gasoline engine is not recommended.
Is Rotella T6 harmful to a gasoline engine?
T6 Multi-Vehicle 5W-30 complete synthetic fulfills the API CK-4 diesel engine specification and the API SN gasoline engine specification.
Is Rotella T5 compatible with gasoline engines?

Approved for use in Cummins LNG/CNG engines and suitable for mobile vehicles running on 100 percent LNG/CNG fuel.
Is it possible to use 15w40 instead of 10w30?
Many medium and big fleets are switching to 10W-30 HDEOs instead of 15W-40 HDEOs. According to a recent survey, 10W-30 HDEO is presently used by around 20% of medium and large fleets (Power Systems Research, 2014). Switching to lower viscosity oil increases fuel economy, which is the most typical reason for the change.
1. IMPROVEMENTS IN FUEL ECONOMY ARE LINKED TO VISCOSITY The primary function of engine oil is to safeguard the engines in your trucks. The combustion cycle produces heat, soot, and acid, all of which must be mitigated by the HDEO. HDEO, on the other hand, has the drawback of adding drag to the engines’ movements. Imagine swimming in honey; getting across the pool and staying afloat would take a lot of effort. Swimming through honey is similar to the movement of your engine’s moving parts through oil. The thicker the oil, as you might expect, the more energy it takes for the engine’s parts to travel through it. There’s nothing magical about a 10W-30 HDEO being more fuel efficient; it’s simply thinner, which reduces engine drag.
2. DON’T FORGET TO WEAR PROTECTION JUST TO SAVE MONEY ON FUEL. While the viscosity of an HDEO contributes to its fuel efficiency, the composition of the base oil and additives protects your engine from wear, smoke, and acid. Because 10W-30 oil is thinner than 15W-40 oil, it has a lower film strength and is more prone to oxidation. To compensate for these flaws, high-quality additives are required in order for a 10W-30 engine oil to protect as well as a 15W-40 and last as long. High-quality 10W-30 oils can work just as well as 15W-40 oils, if not better.
3. 10W-30 ENGINE OIL IS NOT ALL THE SAME VISCOSITY. The claimed viscosity of an HDEO is a viscosity within a range on the SAE viscosity scale, rather than an exact viscosity. The viscosity of engine oil is measured in centistokes (cST) at 100C. “At 40C, W’ grades are measured. The temperature range for 10W-30 engine oils is 9.30cST to 12.49cST. Engine oils with a viscosity index of 9.30cST or lower will deliver better fuel economy than oils with a viscosity index of 12.49cST or higher. As a result, two different 10W-30 engine oils could provide two different fuel economy outcomes. Furthermore, because the 15W-40 label indicates a range of viscosities, the fuel economy benefits of a 10W-30 vs a 15W-40 oil would vary depending on the specific viscosity of the 15W-40 oil. Before you switch to 10W-30 engine oil, here are five things you should know.
4. A BETTER FUEL ECONOMY DOESN’T MEAN YOU’LL HAVE TO BUY LESS FUEL. While this may appear to be a no-brainer, many fleets are disappointed when they move to 10W-30 HDEO and don’t see a decrease in their fuel costs. When all other factors are equal, 10W-30 HDEO uses less fuel than 15W-40 HDEO. However, not everything is created equal. Fuel prices fluctuate, routes alter, cargo weights vary, the weather never remains the same, and drivers’ actions change. The best approach to ensuring that your trucks receive improved fuel economy with 10W-30 HDEO is to design and maintain a precise fuel efficiency calculation procedure. To analyze the fuel efficiency benefits of switching to 10W-30 engine oil, don’t only look at your gas costs. One method is to use data from the electronic control module (ECM) to statistically isolate key characteristics and compare different trucks’ fuel economy before and after switching to 10W-30 engine oil. The main result is that 10W-30 HDEO produces less drag than 15W-40 HDEO, but sometimes noticing the differences requires going beneath the surface of a fuel invoice.
5. VISCOSITY REDUCTION HDEO IS GOING TO BE THE NEW STANDARD. New government regulations for greenhouse gas (GHG) emissions and fuel economy are putting pressure on engine manufacturers to provide more fuel-efficient engines. Furthermore, truck, engine, lubricant, and gasoline producers are always seeking for ways to offer value to their consumers; one method is to create a product that allows customers to use less fuel. The American Petroleum Institute (API) is currently developing and evaluating a new category of engine oil in connection with the EPA’s new heavy-duty emission requirements, which will take effect in 2016. The new engine oils haven’t been given a name yet (like the old ones) “CJ-4), but are now known as PC-11 (proposed category 11). Although the specifics of PC-11 have yet to be worked out, industry trends indicate that the bulk of heavy-duty engine oil will migrate from 15W-40 to XW-30 (i.e. 0W-30, 5W-30, and or 10W-30). The good news is that you don’t have to wait for the entire industry to switch to 10W-30 engine oils to reap the benefits of 10W-30’s fuel economy.
