This oil can deliver not only 85% copper corrosion protection but also 98% lead corrosion protection that is going beyond the CK-4 standards. Thus, it provides engine wear protection on an average of 50%.
The most striking feature of this oil is to provide 1. 5% improved fuel economy performance. Due to this, the oil is more fuel-efficient than SAE 15W40 motor oils. The Rotella T6 engine oil has detergent and dispersant additives.
These additives will help you to deliver lower volatility. As it comes with lower volatility, there will be less fuel consumption. Besides, this oil also features strong shear stability. Thus, Rotella T6 can prevent oil viscosity loss by resisting it. And, the oil pressure can be easily maintained at an optimum level.
If your vehicle has a hard-working older engine, you must use this T6 15W40 motor oil. Not only that but this oil can also be used on all types of modern low-emission engines.
Furthermore, if you have to operate your engine at an extreme temperature, this oil will perform best. It lets your vehicle’s engine protect itself from cold temperature by offering better cold-cranking properties. This oil also provides pump ability at low temperatures. So, your critical engine parts can reach faster in extreme cold climatic conditions.
Rotella T6 5W40 review
In our Rotella T6 diesel engine oil review, we have another product-Rotella T6 5W40 Diesel Engine Oil. This oil is one of the most fuel-efficient oils that are providing 1.5% improved fuel economy.
It also has Triple Protection Plus technology. Therefore, this T6 5W40 oil increases the life expectancy of the engine by providing superior engine protection. The advanced additives that are combined with fully synthetic base oils help to protect the engine from engine wear, friction, building up of sludge and deposits as well as the breakdown of oil.
The Rotella T6 oil also features improved engine wear performance. Most heavy-duty engines face this wear problem which causes engine failure. But, this CK-4 heavy-duty engine oil protects the engine with an enhanced level of wear protection.
Besides, you will be happy to know that this oil offers more wear protection than its previous generation API CJ-4 engine oils. So, you don’t have to worry at all about harmful engine wear.
Moreover, this oil keeps your engine clean with improved deposit control features. It comes with advanced multi-functional dispersant additives. These additives control the formation of dirt, deposits, sludge, etc. in the engine.
They also protect the engine from the effects of soot as well as various types of contaminants. Therefore, it provides super cleanliness.
This oil helps to maintain the flow of the oil at low temperatures. Besides, it offers improved heat resistance ability. Thus, the Rotella T6 5W40 diesel engine oil can easily prevent oil breakdown.
Not only that but also this oil has emissions system compatibility. Therefore, the Rotella T6 oil suits most in low emission fuel engine vehicles.
It provides an advanced low-ash formulation that assists in maintaining vehicle emission compliance. Furthermore, the shearing stability of this oil also resists oil viscosity loss. So, the oil pressure in the engine remains at an optimum level. By doing so, usually enhances fuel efficiency and prevents more fuel consumption.
The Shell Rotella T6 5W40 motor oil meets all the API industry specifications, approvals as well as recommendations. Thus, you can use this oil for your diesel-powered vehicles like tractors, trailers to classic cars as well as heavy-duty diesel pickups that permit SAE 5W40 diesel oil.
Rotella T6 15W40 & 5W40 (FAQs)
What is the difference between 15W40 AND 5W40 engine oils?
Generally, both of these oils have the same viscosity grade of 40. But, the difference between these two oils is that the 15W40 oil has a higher viscosity and the 5W40 has lower viscosity while the engine is getting started.
Which Shell Rotella T6 oil is better 15W40 or 5W40?
Both 15W40 and 5w40 diesel engine oil are better and deliver their best performances depending on the vehicle’s requirements.u003cbru003eHowever, as the 5W40 comes with lower viscosity this oil promotes cold startup of the engine in extremely cold temperature compared to 15W40 diesel engine oil. Besides, the 5W40 engine oil also lubricates the engine parts faster than the 15W40 engine oil.u003cbru003eAnd the 15W40 engine oil performs better at extremely high temperatures by maintaining the oil flow and the oil pressure at an optimum level.
Why is Rotella T6 engine oil good for your vehicle?
Shell Rotella T6 oil is good for your heavy-duty diesel engine vehicle. This oil is designed with triple protection plus technology. Therefore, it has a faster lubrication ability and also provides excellent wear protection of the engine that most heavy-duty vehicles needed. So, this Rotella T6 oil performs oil in diesel as well as gasoline engines.
Can you use T6 5W40 oil instead of T6 15w40 engine oil?
Yes, you can use T6 5W40 oil instead of T6 15w40 engine oil in most cases. Usually, when the engine is at its operating temperature, the starting viscosity grade doesn’t affect it at all. Yet, the issue is when the engine is in too cold condition and also in extremely hot conditions.u003cbru003eIn that case, 5W40 oil performs better in cold conditions and 15W40 in extremely hot conditions. However, it basically depends on your vehicle’s demand and also the outside temperatures.
In this article, we have focused on Rotella T6 15W40 & 5W40 reviews. This review lets you know so many outstanding features of these two Rotella T6 oils. So, you won’t face any problems while selecting the best one for your vehicle.
