New Ravenol Ultra Fuel Economy 0W-8

[ZeeOSix]

Except perhaps a clue...hard to defend any vehicle engineers these days with the junk they produce.

Who's defending them? They need to be defended from CAFE or their heads will explode.

CAFE targets will be vertually impossible to meet, and the car companies will just pay the fines and pass the cost into the price of the ICE vehicles they still make. Call it vehicle cost Inflation due to CAFE, nice.

Thinner oil is NOT going to get them even close. It is a fruitless endeavor and their time and money would be better spent elsewhere. The 1.5% improvement due to 0W8 with 2-4 years to go is essentially meaningless.

Nobody has ever claimed thinner oil is the thing that is going to "get them there". It's part of the equation, has been for decades and will continue to be as long as ICE vehicles are made. That's pretty obvious at this point.

When you add another dumpster fire to the first - you get this thread

There's always room for more dumpsters and matches ... mostly in the MOFT and mathematical realm.

I dont think you understand how these huge companies making complex products work. They have entire teams working on every single component or system in the car to meet goals. Every marginal improvement in every part of the vehicle results in a total result that is more than the sum of its parts. Since low hanging fruit for car improvements have all been picked, fine optimization is key to getting ahead with consumers and gov regulation. 1.x% improvement is not insignificant, in many cases with highly optimized parts/systems engineers would kill for 1-2%, and remember that improvement is compared to already thin 0w-16.

What?! That's what this ENTIRE "discussion" is all about. Will moving to 0W8 result in a meaningful increase in mpgs? My position all along has been no.

Read what I said again. Lower viscosity ALONE is not going to get them there, BUT is one of the main tools that has been used ever since CAFE was invented. And it will continue to be used by the engine engineers as long as there are ICE vehicles. What's so hard to grasp in this?

So with 2 years to go with a goal of 49mpg and car companies selling NEWLY RELEASED models that get 18mpg and "since low hanging fruit for car improvements have all been picked" I'm supposed to believe every manufacturer has a crack team of engineers that is going to piece together 24 mpgs out of 1.5% increases? Sure!

If what you say is true then these manufactures are screwed!!

If that's "one of the MAIN tools" they ain't going to make it...not even close.

He, nor anyone else has never claimed they were going to make the new CAFE targets. See post #121.

Here's my educated guess...0.375mpg is well within the standard error for MPG testing under the best controlled conditions.

How do you or anyone else here know exactly how that testing was done. It was probably more controlled then you think. I've never seen anyone this worked up over thin oil and fuel economy. Just make sure you're set with the ICE vehicles you want before it all hits the fan. Plus, nobody (yet) is forced to use a certain viscosity in their engine ... so go "thicker" and get that added MOFT headroom and forget about it.

I said educated guess...

My educated guess is it's way more controlled than you think. Those places showing that kind of test data do that kind of testing for a living ... people here don't.

I would vote for “ZeeOSix” for president but that would be a political statement, which is a no-no.

 

[ZeeOSix]

I think the CAFE targets should be left as is, and leave them there forever because EV ownership will make up the difference. Engineers really don't have many tricks left to use for ICE, but they will be forced to try as the targets keep increasing. Makes their job very difficult IMO.

Variation is inherent to ANY sampling method used...ALWAYS. This is a fact in statistical inference.

....and he'd fit right in with the vast majority of previous presidents who had a poor handle on the issues at hand with a laser focus on things that make no real difference. He's perfect!

Yeah, well their final figure may very well take that into account. Now you're questioning there testing without even knowing exactly how the test was done?

Now you go on an obvious political personal attack without knowing anything. You have no idea where I stand, but if you actually read what I said above you'd probably agree. It's typically a bad idea to drink and post here.
