Full impact of thin oil on environment

[OilUzer]

I keep reading thin oil is because of cafe ...
Saving very little fuel (is it 0.5 mpg or %0.5?) will help the pollution & the environment and I can understand that it adds up if multiplied by millions of cars ...

I also know xWx20 oils have a relatively similar Noack compared with thicker oils.
However seems like 0Wx8 and 0Wx16 have a much higher Noack!
Also thinner oils (including 0Wx20) can cause more leaks (damage to environment) but let's forget about that for now.

Regarding Noack:
the environment gains from less fuel (due to thinner oil) but get polluted with more oil (higher Noack & potential leaks)

Any studies on overall impact?

You have to buy into some pretty shaky hypothesis's with a history of repeatedly being incorrect on impact measurements to believe the co2 line.
Now pulluted waterways from runnoff and phosphorous..I can buy into being a preventable problem.

It's something that I've oft wondered.

The NHTSA described thinner oils as teh cheapest way for an OEM to make a mileage improvement.

But it locks you into these oils, with manufactured basestocks...which uses energy - I have no idea how much.

SoJ reckons a dino 10W20 could be made cheaply, and be very robust....but would cost s little in economy.

So which side wins, both in cost of ownership, and overall energy conservation ?

Don't know, but I like to think about it.

Why do you assume lighter oils, when specified, result in leaks? I'd remove that assumption right off the bat.

Interesting that the op brought this up but then says to forget about it for now. Why bring it up then?

Not much out there when searching. But yeah, if indeed cars start using more oil because of lower and lower viscosity (leaks and burning) then it certainly could increase pollution in a couple of ways.

https://sciencing.com/effects-car-pollution-5509901.html

"Oil leaked from cars is among the major contributors to water pollution, according to the Washington State Department of Ecology in its website post "Car Maintenance." Each year, people spill 180 million gallons of used motor oil into lakes and rivers, making it the biggest contributor to oil pollution in those types of waterways. Even if you're not near a stream, rain can wash oil into storm drains, where it travels to waterways."

"A car doesn't have to blow a thick cloud of smoke to be a major source of air pollution. Cars burn oil, a fossil fuel that releases nitrogen oxides, which contribute to acid rain and smog."

The result of studies benefit those that paid for the study.

The higher the NOACK, the more volatile the oil is; and is either going to evaporate, or get burned by the engine.

You tree huggers should be running 10w30.

I have used 0w-20 and 5w-20 for many years without any oil consumption or leaks. I don't see why anyone would not want to use it if that is what
is recommended by the factory.

I wonder where WA DOE got that 180 million gallons figure from? I'm skeptical.

That's a lot of people dumping oil down the storm drain.

Tree huggers drive electric cars.

What about that coal fired powerplant to charge that electric car?

Not everywhere is still using coal

I'd like to mention the BILLION GALLONS of gas burned every year by cars sitting and idling in the drive-thru lane........................

That's complete and total BS.

180 million gallons?

That's about a half gallon of oil spilled for every man, woman, and child in the entire unites states (assuming approx. 360 million at current population)

That's impossible.
