Which Motor Oil to Choose

Both 5w40 and 10w40 are winter motor oils. So what’s the difference?
In general, the numbers at the front and end refer to the oil viscosity (or thickness) and operating temperature extremes.
The number ’40’ at the end indicates it’s thicker than the average motor, which is 30. This can lubricate an engine even when it’s hot, unlike other oils whose efficiency decreases with heat.
5W40 oil supports higher mileage engines and in locations that experience winters above freezing temperatures. 5W40 is much better than 10W40 in starting your engine at cold temperatures, down to 5 degrees Celsius. But both may be ineffective when used in freezing climates.

Best rule of thumb - don’t expect proper explanation from RUclips
😂 totally
Then explain it 💁
40 weight is 40 weight at operating temp. They'll both protect the engine thebsame at operating temps. 5w-40 will flow better at lower temps.. as the 5w means the viscosity acts like a 5wt at 0C (32⁰F), while still acting like a 40wt at 100C (212⁰F).
Weight has nothing to do with it. The W stands for winter and is a measurement for oil viscosity at cold temps
@@AH6man weight is common vernacular for viscosity in engine oil. W does indeed stand for winter; specifically the viscosity rated at the freezing temperature of water. The second viscosity rating is measured at the boiling point of water, or typically closer to engine operating temperature. That was the point of the original comment. Sorry for your confusion.
@@EricErnst yea agreed but the larger the gap the less stable the oil is that is why straight 40 weight in perfect conditions is best
Not necessarily
Just look at the spec of the oil and decide
5w40 are oftentimes more expensive because it is simply better
(Lower viscosity at low temp means better protection during startup)@@CarlosMartinez-pc7je
@@onehourmusicbc less polymers the better. It I live in Sadia Arabia Id run straight weight vs multi viscosity. Same base oil quality small the number gap more stable oil is.
This information is. Not correct guys
Best oil to choose is the one for your engine.
5/40 in winter & 10/40 summer if its full synthetic.
In australia normal temperature when hot is around 30 degrees upwards to nearly 40s..so my oil viscosity can be a 30 or 40 if my kms are really high in the 100s and 200s..in winter it can reach just below 10 like 6 to 8 but normally around close to the 10 degrees...so my oil viscosity is 10W...so all up I can use a 10W30 or 10W40..the difference betwwen the 2..is the 40 is much thicker than 30..so if my kilometres are high like over 100ks up to 200ks and over..I recommend you use the 10W40...but 10W30 is perfect as well..when new up all the way to getting close to 100ks and the 200ks..cheers
✔️ Guys Cooking oil mixed with WD40 will make your engine feel like New again ! 💯👌
10w 40 is better for older engines than 5w 40 because the oil is thicker at startup which prevents oil leak through worn seals
As a former car mechanic, I recommend:
0w40 for cold climates and normal use
5w40 for hot climates and normal use
10w40 for hot climates and heavy use
Or use 10w60, 20w60 or 20w50. Whatever k bye
I like to switch a car I buy to 10W40 high mileage full synthetic even if a car oem recommends 5W30. I stay in Michigan where it’s gets cold but not negative degrees cold. Is that bad?
I use 15w-40 in my truck and it works fine
@@lhester379Yes that's too bad, never to that sir, if use the preferred grade for your car please.
Dont censor it, its shell Helix Ultra
Which is best oil viscosity Verna diesel
What about 20W50?
Does anyone know what the modern equivalent of 'super premium motor oil'? Is that a synthetic blend or full synthetic?
oil?
Did i hear oil?
Follow the engine label. 😮
My car calls for 0w-20 but I live in a desert that gets over 105°F in summer. Should I run thicker oil? Also what’s a good and bad temp for your engine oil
you should run 0w20, operating temperature of engine oil is around 100 degrees Celsius up to around 125, and anything over 140 degrees Celsius is considered high temperature that degrades the oil
Your Explanation is Not Accurate!!
The only difference of 5w40 and 10w40 is the Cold Start Viscosity.. 5w is thinner than 10w but Both of them have same Viscosity in Operating Temperature "SAE 40" 🌡️.
It's not that simple.
@@Shadows-RC actually it is
Can we have it?
Not exactly but ok
