Your car will serve you well only if you take good care of it. And one of the most important things you have to do is keep the car engine running in tip-top condition all the time is by regularly lubricating and conditioning the engine using the right motor oil.
It’s only if your engine works well, and is kept well maintained will it give you a good return on your investment. So though you may head to your mechanic to do an oil change instead of you doing it yourself, you still need to know which motor oil to use for your car.
Everyone knows that synthetic oils are rather popular and considered a better option for today’s car engines. Though there are so many types and brands of synthetic motor oils available, 5w20 motor oils are rather popular. These oils are in fact a better choice if you live in a colder climate, where you need thinner oil that quickly heats up and flows easily.
The low viscosity of 5w20 oils creates less friction which means that there is a minimal drag on the engine parts like pistons, crankshaft and valve trains. This, in turn, gives an indirect benefit to you through improved fuel economy. Besides, the runnier nature of 5w20 oils helps the oil pump easily move it from the oil pan to the rest of the engine. This is the main reason it’s a better option if you live in colder climates. However, the 5w 20 oil is relatively safe to use if the temperatures where you live are not too extreme.

The Castrol 03086 Extended Performance Advanced 5W-20 Full Synthetic Motor Oil is just what your engine requires to work consistently even in changing environments. It comes from the huge, immensely popular global company Castrol, one of the most dominating producers for synthetic oil.
They do indeed produce some of the best synthetic motor oils, making their oils a safe choice for car owners. The Castrol 03086 EDGE is one of them, and just what your car and the engine needs to run perfectly.
Unique structure
It efficiently responds to the different pressures, temperatures and demands of the different metal to metal contact points in the engine while driving at varied speeds. This is because the Castrol EDGE is uniquely structured, and engineered with the help of fluid titanium technology. This technology physically changes the oil’s behaviour at high pressures by doubling its oil film strength. This is how the oil reduces the friction created in the engine.
The preferred choice of racing car drivers
This, in turn, provides unsurpassed protection for all your important engine parts so that it performs optimally as you want your car to. The oil is thus highly recommended for use in severe applications like high-performance driving or racing, idling or regular short trips, driving in humid or extreme temperature conditions and while towing and hauling. Sports and racing car drivers, in fact, prefer using this oil for their car’s maximum performance and protection from the wear and tear of racing and sports.
Extended drain interval
Castrol EDGE offers the advantage of a guaranteed extended drain interval of a maximum of 15,000 miles in everyday and normal driving. However, Castrol does not recommend such an extended interval while driving in severe applications or while driving in extremely dusty and dirty conditions. Oil changes will have to be more frequent in these cases.
Reduces engine deposits
With its reduced viscosity, the oil helps reduce engine deposit formation which in turn helps maximize fuel economy and the engine response. All these features make this 5w-20 motor oil one of the most advanced full synthetic oils money can buy. For best results, Castrol recommends using the oil with Bosch oil filters.
