Can I use 5W50 instead of 10w40?
10w-50 is going to give you pretty much the same ambient temperature spread, so it should be OK for the same car, but perhaps a bit harder to find and a bit more expensive as it isn't as common an oil viscosity.
Is 5W-50 oil thick?
So 5W-50 is a very wide range multi-grade oil that is relatively thick oil, that still pours very well at sub zero temperatures, and does not thin out at very high temperatures. 10W-30 is a slightly thinner oil, but it thickens up at sub zero, and becomes quite thin at high temperatures.
Is 5W50 oil good?
A 5W-50 motor oil is suited for a broad range of applications including motorsport, classic/collector cars and extreme driving conditions like towing and high operating temperatures.
Is 5W50 oil thick?
5W50 is what I have ever used in all my cars since 1995. Of course, 5W50 is a better, more expensive full synthetic oil with a higher viscosity index (viscosity less dependent of its temperature) and longer life, so that you can extend your mileage between oil changes.
What oil can I use instead of 5W50?
To use instead of 5W50, you can (in order of decreasing cost): 5W40 if you drive a tight motor and the oil mostly keeps its level on the sump; 10W40/50 if (Cold) Start-up Temps are close to 0º Celsius. 20W50 in a well used eng.
What happens if you put 10W-40 instead of 5W-40?
10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.
Can you use 10W40 instead of 5W50?
Can I Use 10w-40 Instead Of 5w40? If you need a 10w-40, you can use 5w-40. Both oils are equivalent at operating temperatures of 40Wt. Colder oil viscosity is only affected by the first number (with a “w”).
