The main difference between Shell Rotella T6 5W40 and 15W4 is viscosity which allows you to choose one for your diesel engine vehicles. Diesel engines are a unique breed in terms of compression ratios, torque, and output. This new low-emission diesel can run at exceptionally high temperatures, shearing oil at a much faster pace and producing more soot than older diesel.
Use synthetic oil on your automobile as it improves performance, reduces wear and tear, and extends engine life. These lubricants are more efficient than ordinary motor oil because they go through an engine’s components with less friction.
Less friction in the engine means less fuel consumption. Synthetic oils last significantly longer than traditional engine oils, making them less expensive over time. These oils protect against rust corrosion and oxidation induced by oxygen interaction.
In terms of quality and performance, Rotella oils have a long track record of reliability. More and more people are turning to Shell Rotella T6 5W-40 and Shell Rotella T6 15W-40 as alternatives throughout time.

Before going deep into the Shell Rotella T6 5w-40 vs 15w-40 review, it is essential to understand the Rotella T4, T5, and T6.
You may choose from three different kinds of engine oils depending on your vehicle. Synthetic and synthetic blends are better suited to current engines than conventional oils, which are best suited for older and simpler engine models. Even if you’re a vehicle aficionado or at least know a little about motor oils, it might be tough to narrow your search to just one.
The overall oil type of T4, T5, and T6 are:
- Rotella T4 is typical engine oil with additives to improve viscosity, anti-wear, and other qualities. Compared to synthetic and semi-synthetic oils, the significant benefit of using traditional engine oil like Rotella T4 is a 10 percent savings. But during the depths of winter, they are rendered almost useless.
- Rotella T5 is a synthetic mix of semi-synthetic oil that combines traditional and artificial components. It allows for far more extended periods between oil changes than either conventional or completely synthetic motor oils.
- Rotella T6 engine oil is completely synthetic and may be used in any weather situation. This synthetic motor oil, like all others, does a fantastic job of protecting engines, but it comes at a high price.

Understand the difference between Shell Rotella T6 5W40 vs 15W40:
The 5w40 is premium oil, which means it’s been developed specifically for high-performance engines. The viscosity of Rotella T6 5W40 vs 15W40 has major difference. Due to its greater viscosity, 5W40 surpasses 15W40. High viscosity oils flow readily when cold and protect against wear and corrosion when heated.
Industrial engine oil 15W40 is designed to withstand higher loads and higher temperatures than those often found in automobile engines. The viscosity grade 40 is the same for each of these oils. However, the 15W40 oil has a greater viscosity, whereas the 5W40 crude has a lower viscosity when the engine starts up.
Shell Rotella T6 5W40 vs 15W40 – which one is the best?
Both 15W40 and 5w40 diesel engine oils are superior in terms of performance. Both of these fully synthetic oils offer their best results according to the vehicle’s needs. However, since the 5W40 has a lower viscosity than the 15W40 diesel engine oil, it facilitates cold start-up in very cold temperatures.
Aside from that, the 5W40 engine oil also lubricates the engine components more quickly than the 15W40 engine oil. There is no match for the 15W40 engine oil’s ability to keep the oil flow and pressure optimally balanced at high temperatures.
In the conclusion of Shell Rotella T6 5W40 vs 15W40, we suggest that both the products have top-notch quality, and you can decide one that is best for your car’s engine.
Shell Rotella T6 5W40 and 15W40 heavy-duty diesel oils provide extraordinary lubrication for your vehicle’s engine and good protection against wear. For optimal protection against wear and corrosion, as well as a reduction in friction and heat, you can use both of these premium-quality oils.
These products also provide benefits to essential parts like spark plugs and cylinders by decreasing the buildup of sludge and varnish, as well as a reduction in the amount of smoke and an improvement in horsepower.
Q#01: Why T6 5W40 is more commonly used than T6 15W40 oil in your engine?
Answer: T6 5W40 oil may be used in most circumstances instead of T6 15W40 engine oil because its start-up viscosity grade seldom affects an engine after it reaches operating temperature. However, the problem arises when the engine is too cold and too hot. In this scenario, 5W40 oil works better in cold circumstances, whereas 15W40 performs better in excessive heat. However, the demand for your car and the outside temperature is the primary determinants.
Q#02: How long does Shell Rotella T6 last?
Answer: As long as you use Shell ROTELLA T6 Full Synthetic heavy-duty diesel engine oils regularly and correctly, your engine should last for up to 10 years with no significant issues (500,000 miles on a single cylinder).
Q#03: What’s the difference between Rotella T5 and T6?
Answer: Rotella T5 and T6 perform better in cold climates since their oil flow features enable you to safeguard your engine at a lower temperature. However, if you must drive it, its temperature decrease makes it the best option for keeping you cool.
