Short Review on the 0W40 Engine Oil

The 0 indicator represents how incredible it can be in the extreme winter season. Being extremely thin and synthesized, it ensures an easy flow level and even in summers, the 40 indicator prevents the oil to break down and works great.


  • Fully synthesized
  • Expensive
  • Doesn’t need oil change frequently.
  • Give extra mileage to vehicles.

Short Review on the 5W30 Engine Oil

Well, this oil has been the traditional oil that can work magnificently on a balanced atmosphere. This works just great on both moderate winters and summers and can be your best pick for the limited budget.


  • Synthetic blend
  • Easily available
  • Protect engines from being worn out
  • Relatively less expensive.

What does 5w30 mean?

W means that the oil is made for winter and the numbers stand for the oil’s viscosity. The viscosity is the regulator by which we can characterize the oils. By reading the numbers, we can say that the product is developed for low temperature. And it is one of the most widely-used oils in extreme conditions for their thinness and overwhelming performance.

Can you mix 5w30 and 0w40?

In terms of mixing, it is wiser to mix only the grades, never the brands. These two can be combined. The first one is thicker than the later and the added viscosity will ease the start-up flow. The temperature is another crucial factor which will decide if you can mix them or not like it is generally hot in Africa so both of the oil will work just fine but in a colder region like Europe, the 0w will have the upper hand.

What does 0w40 used for?

This engine oil is your best friend in extremely cold weather. A look at the numbers will assure you of the allegation. The oil has an unparalleled ability to ease flow to start and enough weight to it to avoid any sorts of break down. Suitable for diesel and gasoline-powered engines, the oil is good for everyday vehicles with an industry best fuel economy.

What does 0w40 mean?

The properties of the oil have justified the oil’s fame in recent times. As the names suggest, it will flow like weight o in the colder region but with a viscosity of 40 when the operating heat level is enabled. Fully synthesized in the making, it gives extra mileage to the vehicle without frequent oil changing. The engineering formulation allows the oil to flow with such grace in winter and still provides protection like weight 40 without breaking down. If you are more interest in other comparison then i suggest you to look at 0w20 vs 5w20.
