Which Motor Oil to Use?
10W40, 5W40, 15W40, or SAE 40

Selecting the right motor oil to fit your car is
crucial to ensuring the highest performance of
your engine and its longevity. The range of
options available, including 10W40, 5W40, 15W40,
and SAE 40, is a bit complicated. In this blog,
we'll walk you through the aspects to consider
when choosing the appropriate engine oil
viscosity for your car to help you make an
informed choice.

Know Viscosity Ratings
Viscosity ratings indicate the characteristics of
flow in an oil at various temperatures. They are
comprised of two numbers, separated by the
letter "W" (winter) as well as the letters "SAE"
(Society of Automotive Engineers) for mono-grade
oils. The first number signifies the viscosity
of oil at cold temperatures, and the second
indicates its viscosity when operating at
temperatures normal to it. For instance, 10W40
is a reference to the viscosity of the oil at
low temperatures, whereas 40 represents its
viscosity at operating temperatures.

Check Manufacturer Recommendations
Automobile manufacturers usually provide specific
recommendations regarding the viscosity of
engine oil in their automobiles. These
suggestions are based on extensive testing and
engineering in order to ensure maximum
performance and durability. Refer to the owner's
manual of your car or get in touch with your
manufacturer for the appropriate viscosity,
whether it's 10W40, 5W40, 15W40, or motor oil
SAE 15w-40. These guidelines will help you keep
your warranty intact and ensure the proper
operation of your engine.
5
Age and condition of your engine
The condition and age of your engine affect the
selection of the proper viscosity of your engine
oil. Older engines that have more mileage could
benefit from oil that is slightly thicker, such
as 15W40 or SAE 40. These oils offer better
lubrication and reduce the amount of oil consumed
by filling in gaps in worn components of the
engine. However, engines that are newer and have
smaller tolerances may require more oils, such as
5W40 or 10W40, for the highest performance.
6
Driving Behaviours and Conditions
The way you drive and the conditions influence
the selection of the viscosity of your engine
oil. If you often engage in heavy towing,
hauling, or speed- driven driving and hauling, a
viscosity-higher oil such as 15W40 or SAE 40
will provide greater protection from the heat and
stress on your engine. However, in the event that
your driving is mostly short journeys or
stop-and- go, a lower viscosity oil such as 5W40
or even 10W40 might be a good choice.
7
Impact of Fuel Economy on your Car
If the economy of your vehicle is an important
issue for you, take note that oils with lower
viscosities like 5W40 or 10W40 usually provide
slightly higher fuel efficiency. Thicker oils
move more fluidly, which decreases drag and
friction on engine parts. However, the
differences in efficiency between different
viscosities are typically small.
