When should I use 5W 30 oil?
5w30 oil is particularly well suited for cars driven in cold climates. Unlike oils with a higher hot temperature rating such as 10 or 15, 5w30 oil can flow freely enough when the engine is started at low temperatures to coat and protect the engine’s internal components.
What does 10w30 mean?
The 10W30 designation on engine oil means that the viscosity of the oil is rated at 10W when an engine is cold and 30 when the engine is hot. This is different than an oil labelled 5W30, which has a thinner viscosity when the engine is cold at 5W.
What’s the difference between 5W30 and 10W30 oil?
It is recommended for use at -31°F up to 95°F / -35°C up to +35°C (outside temperature). It’s more fuel-efficient and flows faster as well. 10W30 – While still quite “fluid”, this oil is a little bit thicker at low temperatures than 5W30, making the process of starting your engine a little bit harder.
What is the viscosity of 10W30 multigrade engine oil?
10w30 multigrade engine oil has a viscosity grade 10 for lower temperatures and a viscosity grade 30 at higher temperatures. 10w30 oils have a viscosity grade of 10 at low temperatures and a viscosity grade of 30 at high temperatures. It has a low viscosity grade at lower temperatures which means the oil is thin at such temperatures.
What kind of oil is in the engine cap?
The cap on the oil reservoir calls for 5W-30 oil. I know that the engine is full of 10W-30 oil. I know that the number ahead of the “W” is an indication of viscosity at very low temperatures.
Is it OK to put 10W oil in my car?
With temperatures going down to 20F a 10W oil will not be an issue. Should you be faced with that kind of “extreme” cold you can just let your car warm up for 30 to 60 seconds before you start rolling.
It is recommended for use at -31°F up to 95°F / -35°C up to +35°C (outside temperature).

It has a low viscosity grade at lower temperatures which means the oil is thin at such temperatures.
Can you use 10W30 oil on an old engine?
Yes, it will be prudent to use thick engine oil like 10w30 on older engines and motors. Thick engine oil will improve the oil pressure of older engines. This is because when the engine gets old, their clearances extend, thus demanding less liquid oil for better protection.
What kind of oil is used in a diesel engine?
5w30 is used in light-duty diesel engines, light-duty petrol engines, and automotive gasoline engines. 5w30 engine oil is preferred for engines working in cold climates, as it gives good flow at lower temperatures.
