run 5w-30 in a car long-term with oil passages and piston clearances designed for 0w-8 (or 16) and see what happens. it isnt pleasant

You should 100% use the weigh that the manufacturer recommends especially in any newer vehicle.

Run whatever the engineers tell you due to your bearing clearances, not what the internet tell you! LMAO.

if it’s got a piston it’s getting 15w-40

Truck designed for 0w-20 I run 5w-30 and never had issues, it actually runs better 😂

Toyota is also using a 0w8 in many cars.

Mudd I guess :
I wouldn't run 0w20 or 5w20 in anything. Its getting 5w30 if it takes 20, and 5w40 if it takes 5w30. If it takes lighter, I wouldn't buy it.

you know more then the manufacturer who has literally nothing to gain from using another oil?

because oil runs at room temp qnd a plastic case with metal ball is an accurate representation of an engine 🙄

This only shows the difference of the oil cold

You know the epa is forcing companies to use lighter weight oil right? I’ve been noticing when I look up cars at work on all data a lot say that 0w20 is USA and Canada exclusive and outside of North America they recommend 5w30

dry engine kills, low viscosity gets to it quicker

Liqui moly 5W-40 warm up before you push. And I run this in my b48 G30 530i.

My old Buick calls for 5w20 but it leaks and burns a quart a week so it gets whatever I have… some weeks I’m adding 15w-40 from a diesel and then the next it’s getting 0w20 recycled from my VW

Doesn’t really matter when you get it to operating temps the viscosity is very similar no matter what weight it is, 0w is just how good the flow is in cold temps

Tristan :
5w-30 is the perfect oil, some of the most reliable cars have used this and been reliable. EPA regulations are ridiculous running such a thin oil + forced induction with higher compression ratios. Thicker oil cushions much better, so you have a higher force on bearings, but running a thinner oil? How does that make sense…

My car uses 0W20 and it has almost 300,000 miles on it. She still runs like a champ
