Synthetic Oil

[HEMIMANN]

PUP is what we thought it was (apologies to the late, wacky coach Dennis Green):

Here is Lake Speed again from a year ago with differences between Pennzoil Platinum and Ultra Platinum.
Takeaways -

- Both are same visosity in 5W-30, but are a very light 30 weight (only 10 cSt @ 100C)
- PP is Dexos licensed, PUP is not
- PUP has MORE antioxidant, detergent, and antiwear than PP
- PUP is BETTER than PP, despite not being Dexos licensed, in terms of not degrading as fast (oxidation), cleaning engines (detergency), and wear prevention - just as advertised and as we thought in the last decade.
- PUP can be used in Hemi, but needs more moly than stock (has only 97 ppm Moly), which is why guys add LubeGard Moly supplment
- PUP is marginal for heavy towing due to the light 30 weight viscosity. I stick with Red Line 5W-30 for Hemi.
- PUP looks like a great oil for small 4 cylinder engines with single injector GDI and turbos.
- PUP is BETTER than a basic Dexos oil.

Is Shell planning to Dexos license? Who knows? Maybe they just push PP because most buyers are price sensitive, so no point licensing their super oil?

Bottom line - PUP is preferred to PP (per me). Other Dexos oils might be as good, or not, unless somebody does a VOA.

What Makes This Oil So Special?

Pennzoil Ultra Platinum is chemically different from Pennzoil Platinum. So what makes it so special? Going beyond the elemental analysis, Certified Lubricati...

see my post on previous page, PUP has dexos on the label.

When did that happen? Spec sheet doesn't/didn't?
I'm not getting all post push notices, fyi

I dunno when, I am guessing fairly recent.

Weird, PUP specs old GM specs but not dexos on their page, and is on some bottles, weird?

Is GM6094M the same as Dexos?

dexos1™ is factory fill and service fill in all GM gasoline engine vehicles. dexos1™ supersedes the GM6094M, GM4718M and GM-LL-A-025 specifications for 2010 and older GM vehicles and is now the only motor oil GM recommends for those vehicles. GM's brand of dexos1™ is a synthetic blend, not a full synthetic.

If it doesn't say dexos, then it isn't dexos, unless it is super recent.

Catch cans are an afterthought/ bandaid to a huge engineering oversight germane to GDI engines. Toyota was the first to correct the problem with an obvious fix by adding port injectors.

Sad fact: GDI engines are sludge/ carbon generators at a level much higher than old fashioned PFI.
I recently came across an internal memo of one of the major manufacturers addressing the issue by saying that the engine oil change needs to be accompanied by adding Techron to the fuel tank EVERY oil change!

This is tantamount to an admission of deficiency in design. The proclivity for LSPI in GDI engines is another problem.

This is the world in which we live, and must function. Meanwhile, the critical nature of staying on schedule regarding maintenance has intensified.

Some engine builders are finally adding the port injector for rich burn mode instead of sooting the cylinder with the direct injector.
It's unbelievable they implemented GDI incorrectly to save money. A four cylinder only needs 4 more injectors + software.
And they shouldn't be doing GDI at all for V8 truck engines!

Well heres a thought for you to mull over,all Hellcats employ an air/oil seperator aka catch can,but they vent it back into the oil pan,as FCA realized they couldn't run a stand alone catch can,and count on owners emptying it on a timely basis.Look at the differances between a Hellcat valve cover and a standard 5.7/6.4 valve cover,and you'll see the obvious differances,and how the engineers developed a air/oil seperator system that doesn't require constant maintence.

I don't get why this is such a big deal. Coalescing crankcase breathers have been available for diesels for 30 years. May even be mandatory today.
Here in 2024, Harley recently announced their FIRST ever crankcase breather, always needed for an uneven-firing big bore engine.

I mean, wtaf?

I've never really considered Harley to be at the forefront of new technology

My god, man! Where have you been?
I got a 4 valve head and fuel injectors!

Ok, ok - i did have to add my own crankcase breather. And they still use a clunky, mechanical torsional vibration damper instead of a rubber or viscous one.

 

[Burla]

CA emissions wont allow for any breathers that I know of, we were punching hole in valve covers in the 80's but we knew it was "wrong". The cars were from the 60's and they still didn't have breathers right out the cover. More then 50 years they have been worry about fumes, lol.

Think about the oil we were using in the 80's, we had to punch holes- pvc's didn't last for isht.

Don't forget WHY the VCT transmissions made a come-back: GDI engines which have a NASTY problem with LSPI. By not having piston slow down at or near TDC/BDC cause load related Low Speed Pre Ignition, the VCT's correct only one of several inherent engineering challenges! VCT's are WAY to effete to handle a truck with a V-8.

And just think! The PCV valves of today are heated!

 

[Burla]

There is an easier way to solve that, go to pi instead of di problem solved. My guess 90% of truck owners will give 15% HP to not worry about lspi. But lets be honest manu's love di and shorter lasting engines. Japan Shaken.

What's left? They wrecked diesels with their exhaust aftertreatment factories.

That's the main reason I won't get a moden diesel.

I would love to have a Cummins but I dont want to be on the side of the road because a NOx sensor isn't working and the truck is derated to 5mph.

Plus the dumb diaper regenerating and the DEF fluid and all the rest of it.

Must drive users nuts.
