For the 5w20 motor oil, the twenty indicates that the motor oil has a low viscosity and is also thinner in high temperatures. So, you can substitute 0w20 with 5w20, but the latter will offer more resistance in its flow. Not saying you can't use what you want but a mechanic that says you can use different grades doesn't know his job very well. Whether you use 10w30 instead of 5w30 oil actually depends on the situation. 20W40 oils on the other hand work better at a bit higher temperature. 4) 10w30 oil is less likely to cause engine damage than 5w30 oil. But since the concentration of whatever waxes in the 10W-XX is diluted, it would seem like the viscosity would be lower due to the 0W-XX. It lubricates, cools and cleans the engine parts. You’ll find that older engines use the SAE30 type of oil, while a mower manufacturer recommends often 10W 30 type of oil on modern mower engines. Q. My assumption is that the new oil took. 10w30 Nissan. In warmer regions, the thickness of 10W30 will make it easier to flow. Synthetic 5W-30 can be used in all temperatures.

A: NO, this is NOT the same as 0W-30 oil. 0, but i gotta tell you that I am completely disappointed. From my understanding, both 5W-30 and 10W-30 will have the same viscosity at operating temperature. SAE 30 vs 5w30 (The Short Version) Basically, SAE 30 and 5w30 have the same rating or viscosity of 30 while hot, but when cold their ratings differ. While both 5W-30 and 10W-30 oils are commonly used in vehicles, they have different viscosities, with 5W-30 being thinner than 10W-30. Mobil's 0w40 is actually right in the middle of a 40wt, it's not on the thin side like their other viscosities. 25 MPG per vehicle if they changed to 5w-20.
