0w40 vs 5w40. Learn the key differences between 0W40 and 5W40 engine oil. Find out which oil viscosity grade is better for cold weather performance, fuel economy, and ease of starting.

This video explains what the numbers on motor oil mean - like 0W, 5W, 10W, etc. You'll understand viscosity grades and why they matter when picking the right oil. See how thinner oils like 0W flow faster when cold but thicker 5W or 10W oils may handle heat better.

Discover the advantages and disadvantages of 0W40 vs 5W40 oils for your vehicle:

Benefits of 0W40 Oil:

1. Exceptional cold weather flow
2. Easier starting in winter
3. Improves fuel efficiency
Benefits of 5W40 Oil:

1.Good viscosity balance in hot and cold
2. Meets requirements for some luxury cars
3. Handles extreme heat conditions well

Find out which is better for your driving needs - 0W40 or 5W40. Learn whether using 0W40 instead of 5W40 oil does any harm before substituting. Get the facts you need to decide the ideal motor oil grade for your car, truck, or SUV.

An 0w oil passes the SAE viscosity rating test for 5w or 10w or 15w or even 20w.
A 40 grade oil will pass SAE viscosity test for SAE 30 or SAE 25 or even SAE 20 or lower.
0w-40 oils tend to just scrape through the hot end test for 40 grade and are close to 0w-30 in reality. I use Mannol 0w-40 to BMW LL-01 or LL-04 year round in my BMW diesel engine

Hello! Lada Granta 1.6 16v-ben a 0w40 vagy a 5w40 a jobb választás. Téli hömérséklet -10-15, nyári + 35-40C. A gyári ajanlás: 0w40 - 40-+30, 5w40: -30-+35C. Köszönettel!😊

I would go for 5-40, unless its 25 Celsius or colder.

Thicker because GDI dilutes oil with fuel

hello! does 0w and 5w oil, for example at -10 degrees, behave the same? or is 0w always thinner than 5w?
