Why I Switched to 0W8

[NitroM3]

Seems like a thin oil like that wouldn't stay on parts very long.

This would be determined by the flash point of the oil I would think. Even higher viscosity motor oils may have a flash point that is not suitable for the engine they are intended to be used in?

 

[NitroM3]

Don't forget to add a little MMO, just in case it decides to thicken up a bit!

You are brave, although I use and still use Marvel Mystery oil since I guess the 70's for various things I get the distinct impression reading on other threads that many member's on this forum don't care for it use these days?

You think?

I wouldn’t get near that “oil”

I would think it flashes as you pour it in.

Championship race teams are now qualifying on highest quality 0W8 motor oil.
They then find it unnecessary to rebuild engines prior to race day.
The bearings are unscathed.
Fly Erica Fly..

Yeah, but Erica is just running the 08 oil for 6.5 seconds at a time.

I haven’t seen it used in years. Decades even.

I knew of someone who used it as a fuel additive. This was back in the 60’s-70’s on a carbureted engine.

I wouldn’t use it on a modern engine.

 

[SlavaB]

Not to show off, but when I only had a Kia in my garage I cared about “what’s the next oil I’m gonna use” BS. When I’ve got my first Porsche (yeah, it’s an entry level Macan, but still has this Porsche badge on it) I’ve realized that it’s the car that provides you with the incredible driving emotions, not oil or anything else. I only use the OEM recommended oil and intervals now on, there’s more important stuff in life

 

[BMW Dom]

Hmm I see some members run in a packs?

Ever tore down an engine that the bearings got so hot the oil failed? Be honest? Most will generally diagnose it as an engine that was run without the proper oil in the sump. There are specific indicator's that are different from low oil to an oil flashed.

As for Marvel Mystery Oil I take it then you have used it and have experience and also it obvious I am interpreting from your comment something that must have failed using it?

For us, it’s experience without MMO

This thread has devolved into personal attacks and bickering. Lock time

 

[Astro14]

Unlocked, now that everyone has had a chance to calm down.

Thanks

^^^ Don't take your finger off the lock button, lol.

 

[aquariuscsm]

Why stop at 0W-8?

 

[ZeeOSix]

I'd be interested to know if the OP monitors the oil level and sees any increased oil consumption.

That's LAT though, probably the only company that has more dye in their oil than ZDDP... and they have a lot of ZDDP.

Light oils require a different mindset when it comes to formulating. You can't just toss an SP add pack into a Yubase 4 base oil with a 24 SSI VII and call it good. Shear stability, thermal stability, and volatility have to be rock solid. The margin for error is much smaller. It takes a good bit of R&D to get reliable and repeatable results from light oils. Some companies have the ability and mindset to make that happen, others don't.

If you want to know who's doing light oils successfully, go to an NHRA race, check out the Pro Stock cars, and see what company is on the cars.

Yep, because these puppies can be quite volatile:

Speaking of Noack, how does something like 0W-8 and 0W-16 shown above meet the 15% max limit? Or are they not API or ILSAC rated?

There were exceptions made initially for these grades, they didn't have to meet the limit. Not sure if that's still the case now?

The main brands of 0W-16 being sold have the API SP rating and ILSAC GF-6B rating, so I'd expect them to meet the 15% max Noack unless there is some other Noack spec for them. Not sure what 0W-8 bottles show for ratings.

tgmo was sub 15 by the time it hit our shores. non-API 0w16s were already circulating in the 90s
