Our motor oil market continues to undergo a period of dramatic change as the result of three factors: changing emissions ratio, increased fuel economy requirements and the need to maintain durability under severe operating conditions. This has lead to the development of new engine oil technology designed to operate in vehicles with the latest after treatment systems, while also delivering ever increased durability and fuel economy improvement.
It is expected that the need for engine oils to deliver even greater levels of fuel economic improvements may have the single greatest impact on the type of engine oil that is used over the next five years.
Improving fuel economy
The need to increase the fuel efficiency of vehicles is driven by a number of factors including:
-- reducing carbon dioxide (CO2) emissions
-- lowering operating costs
-- reducing fossil fuel consumption
The role of engine oils
Engine oils can contribute to improvements in the fuel economy in two ways:
-- As an Enabler by providing high performance robustness that allows changes to engine design and after-treatment technology without impacting the fuel economy;
-- As a Direct Contributor through formulating changes which maximise the fuel economy.
Both of these roles are interlinked and ensuring the right balance of components (additive chemistry, viscosity modifier and base oils) by selecting and tailoring it for each application is essential to achieve the optimum fuel economy improvement.
Toyota Genuine Motor Oil
Toyota genuine oils are formulated to meet the needs of Toyota vehicle components, recommended by Toyota Manufacturer and are used in all Toyota vehicles. Toyota Lubricants are classified ensuring American Petroleum Institute Classification, ILSAC Standard, and ACEA Standard, and by viscosity standards using the SAE Classification. These are used as major references for selecting the motor oil that is suitable for a vehicle's usage area and usage conditions.
Using Toyota Genuine Motor Oil is not only recommended by Toyota Manufacturers but also it gives you total performance required for the engine components. There is strong research work done behind Toyota own formulated Engine oil that ensure the safety & performance of your vehicle & longer the vehicle's life.
The value of Engine Oil in fuel economy
The development in the science of engine oils and its efficiency will provide greater levels of improvements in the fuel economy and will enable cost savings for both OEMs and vehicle operators. Since new after-treatment compatible engine oil technology has delivered greater value by ensuring emissions compliance through the protection of advanced after-treatment systems, the next generation of fuel efficient engine oil technology will provide greater value, often directly quantifiable in terms of cost savings or avoidance of fines obtained through its usage.
As we will know that Improvement of engine fuel efficiency is one of the most important goals of current automotive development and maximising the contribution of engine oils to fuel efficiency is a very important part of this process. Engine friction modelling, based on fundamental tri-biological considerations, has shown that further engine friction improvements are possible through engine oil reformulation. This reformulation should minimise friction under hydrodynamic conditions through modification of the rheological properties of oils and should also minimise friction under mixed and boundary lubrication conditions through changes in the chemical composition of the oils.
These improvements can be achieved by appropriate selection of base oil as well as by the use of effective friction-reducing additive systems. A very important consideration in formulating these highly fuel-efficient oils is their ability to retain their fuel efficiency during the entire oil service interval.
As wear increases, the efficiency of an engine declines. Valve train wear slightly changes the valve timing and movements whereas the ring and liner wear affects the compression. The wear hurts fuel efficiency and power output by an imperceptible amount at first. Similarly, efficiency continues to decline as the process of wear goes on. Thus, optimising the wear protection is an efficient way of reducing the fuel consumption over the life span of an engine.
However, an engine wears at a certain rate - sometimes slow, sometimes fast. The rate at which this wear occurs can indeed be influenced by lubrication in many ways. In certain exceptional cases, wear can be nearly held in check. Nurture your oil and you nurture your engine. After all, what comes in more regular contact with the engine's critical frictional surfaces than the lubricant that bathes them?
Most automobile engines have a long life expectancy. It is due to the wide range that many consider as an especial opportunity - perhaps you see it as well. The specific life of a particular engine is largely influenced by its wear rate, that is, the amount of metal that is worn away from frictional surfaces per highway mile, per year, per gallon of fuel, etc. This wear rate in turn is influenced by such things as driving patterns, climate, engine design, environmental contamination and lubrication. A few of these things are in the realm of car-owner control, but many are not.
Some have observed that peoples' motives and objectives differ radically when it comes to the selection of automobiles. This is reflected not only in the cars they own but also in the way they drive, the fuel they purchase, routine maintenance and general upkeep. Therefore, a good starting point in customising motor oil selection and lubrication practices for automobiles is to get a better understanding of an owner's objectives and how they relate to their chicer of lubricants.
However, one can also improve the gas mileage by 1-2 percent by using the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1-2 percent.
Moreover, the careful selection of motor oil can have a noticeable positive influence on fuel consumption as for many car owners, better gas mileage is of little concern as evidenced by the kinds of cars they choose to own. For others who tend to pay more attention to their savings, anything that saves a penny will attract their attention. However, some lubrication options that offer enhanced fuel conservation might also be more expensive and perhaps also provide less protection against engine wear and endurance. Incidentally, if you are an environmentalist, any lubricant that also saves you gas money, by default, is good for the environment. When there is less fuel burned by your car's engine, there are less harmful emissions being exhausted out of the tailpipe.
