New Ravenol Ultra Fuel Economy 0W-8

[Shel_B]

If they used Red Line 20W-50, the engine likely wouldn't survive the race. The hydrodynamic friction with the 0W-16 already contributes a 75°F temp rise across the bearing. The temp rise through the bearing (in those engines) is ~10°F for every 0.6 cP increase in HTHS. Their oil is ~2.3 cP and Red Line HP 20W-50 is 6.1 cP. The bearings would likely give way to fatigue from the friction and heat, that's if you can still get sufficient oil flow. They run way too tight of bearing clearance to run a 50 grade oil.

Also, doesn't NASCAR require the use of certain viscosities?

But when you need a $10,000 new engine after it wears out after 100,000 miles on 0W-8, those $72 a year savings won't cover it.
Also, all the top off oil you would need to add due to the increased engine wear/oil consumption could use up the $72 a year.

But you don't know that any of that is true, or that it would happen

But seriously, I honestly would feel very uneasy if I ever had to use a 20 weight or 16 weight or 8 weight oil.

It's 2022 Bill. EVERY factory fluid is low viscosity now. Trans, differential, even brake fluid.

Yes, I know. It's great for the oil companies, as they can put less product and more water into their fluids to make more profit.
Kind of like going to a McDonalds for a large coke with ice, and half the drink is ice (which is free water) which increases the fast food company's profits. The cola is much thinner because it's half water. The future is getting worse, not better (in my opinion).

The future I would appreciate more is if we were all using European A3/B4 Synthetic oil and not 0W-16.
The only way I can wrap my head around it is to realize the motivation (CAFE), and ignore owners manual 0W-16 or 0W-20 recommendations
and use a viscosity which would have a higher HTHS to protect the engine better.

Oil that's been watered down? Are you actually suggesting that oil companies are diluting their product to make them thinner and to save money? Have you looked at any of the VOAs here to see just how much water is mixed with the oil?

 

[Jimmy_Russells]

TIL that oil and water do actually, in fact, mix.

Well, I hope the entire industry moves to 0W-8. Lets see how long those engines last. If we see engines on 0W-8 making it to 200k or even 300k miles with little to no engine wear, then I will change my mind about thin oil. But until that happens, it's only 5W-30 for me no matter what the owner's manual says. I heard that 5W-30 has more market share than 0W-20/5W-20 combined, so at least the majority of oil buyers are still on 30 weight oil.

From what I understand, Toyota-model taxicabs are achieving 200,000 miles on 0W-16.

FWIW, I'm running 5W-30 in my Camry, and I feel that the greater HTHS affords more protection for my driving scenario, but if I were just driving around town, short-tripping, I'd certainly consider a 0W-20.

Bill7, you're making yourself sound like a fool. I'm telling you that as a fellow human being, this is one of those moments where it's good to stop before you dig your hole any deeper. You're trying make a point about something your posts show you don't know much about.

Again, nobody is forcing you to use a low viscosity oil. If you like 5W-30, run 5W-30. I can assure you nobody here will lose a wink of sleep over it.

Keep in mind the 1.15% improved economy over a 16 grade. Let's call it 1.5% over a 20 grade.

So if you spend $400 a month on fuel, you're saving about $72 a year, which I don't think I would call a rounding error. That's more than a full tank for most vehicles, just from using different oil.

$72? That IS a rounding error.

Well look at mr money bags over here

When you're talking about $4,800/year in fuel costs, yes, it's a rounding error, Mr. Jimmy's are Rustled.

 

[sk_pete]

A 1.15% increase in fuel economy over 0W-16? Are we reading that correctly? Lol

Literally chasing flea farts. With electron microscope.

f the thickies want to see how well low viscosity oils can hold up to extreme conditions, look at NASCAR. They run small crank journals with tight bearing clearances and a 0W-5 oil for qualifying and 0W-16 oil on race day.

Can you provide a link that shows the differences in the crank journal design/size compared to a similar engine used on the streets? Just how much smaller are they?

Keep in mind that MOFT is also a function of bearing RPM. If those engines lived a lifetime of running a very low RPM it might be a different story.

Maybe I'm weird or something but a free tank of fuel once a year with no other detriment sounds alright to me.

 

[ZeeOSix]

the 0w8 is currently used in the new toyota yaris in europe, toyota gives a guarantee of 10 years or a maximum of 160,000 km. i think japanese know what they are doing.

Engines specified to use 0W-8 and 0W-16 do have design aspects that take that low viscosity oil into consideration. Wider journal bearing, specific materials and coatings, etc. That's why ILSAC has put a different designation on those oils, so people don't mistakenly put 8 or 16 into an engine not designed for it.

Yeah right and how many people would lose their minds if all 1.5% cash back rewards credit cards stopped offering the reward.

My wife is a CPA and the controller of a medium sized business. I can assure you that rounding errors are a lot smaller than 1.5%.

I'll wait for 0w0 or straight kerosene.
Zero saps, cat will last forever.
Each oci comes with free engine . factory filled(for life)and sealed..
Eci, engine change interval

You are. And again, we have no concrete data/evidence to show that there's no "other detriment" right now.
