How Much Synthetic's in that "Blend"?

[Dick in Falls Church]

Excellent article in the Sep "Lubes"n"Greases by Thomas F Glenn, President of Petroleum Trends International.

The primary question is"
Q How much synthetic is in a synthetic blend?
A. Correct!

Summary--some use almost 50% PAO.
Some agree that there should be about 50%, but doesn't need to be PAO, since Group III does well.
Most elect to use Group III rather than PAO because of cost, but feel that 10-20% is sufficient to give "measurable performance advantages".
And then there are a few that "reportedly" say that you don't have use actually have to use any synthetic base stock at all, because the additive package comprise enough synthetized molecules.

Let the buyer beware!!!

Hey, what issue of Lubes N Greases?

 

[Dick in Falls Church]

September 04

 

[TallPaul]

Thanks. I don't recall the article and can only find up to Aug 04 in my magazine stack. Guess it's still on its way.

 

[Pablo]

Ain't got my Sept 04 issue, neither.

I got mine today. Sounds like marketers are trying to label all they can as synthetics now.
But from a few articles in the Sept issue, it looks like this time they're going to have some real opposition.

 

[TallPaul]

Wow! Finally got my Sept Lubes N Greases today.

Also got my e-copy of the Sept-Oct Machinery Lubrication today and and it has a Synthetic Lubricants Buyers Guide in it. The issue should be posted on their website soon.

TallPall, Can you come up with a link or a url for the above. I'd like to see that one. Thank you.

krholm. 1Fmf posted the link in the Car and Truck forum at this thread.

It takes a while to download, maybe 10 minutes if you have a fast connection.

What is even more unsettling is the next queston in the article:
Q How much synthetic is in a full synthetic?
A. Correct!

 

[MolaKule]

In a full synthetic (I define a full synthetic as as a PAO, PAO/ester, or PAO/AN/ester) and it's around 80-85%, the rest is add pack.

 

[dropitby]

I am not sure but I would venture to guess without making wholesale changes to there formula the oil that may be what we read about Drive Clean Plus will lower its % without notifying anybody.The only sure thing may be buy your Redline and add to your sump as needed.

 

[MGBV8]

What is the add pack - carrier mineral + additives, or ester + additives?

 

[MolaKule]

The add pack consists of:

1. VII - little if any necessary to tune taget viscosity.
2. Detergent
3. Dispersant
4. Antiwear agents
5. Friction reduction agents (not much needed here).
6. antioxidants

For a comprehensive list of additives and their functions, please see:

The claim by Synlube is that minerals are included in so called true synths, which spoil package for extended drain.

If M1 is pure synth + adds then this claim is false (synlube is not an option).

With regard to esters the tendancy is to use these in race oils. On the basis of no expense spared, with a road car with short trips etc can too many esters cause a problem.

Small amounts of mineral oils as carriers for additives (commonly called - "process oils") have little effect on a full synth's OCI.

Does it say how much synthetic is in the motorcraft 5W20 and 5W30? Or are there any guesses? I kinda assumed its as little as possible to keep costs down. Like maybe 10%

 

[Mackelroy]

((Does it say how much synthetic is in the motorcraft 5W20 and 5W30? ))

My nose is very accustomed to high end synthetics. They all seem have one thing in common they have a distinqt plastic smell. All the Hydrocracked oil, whether syn blend or or sold as full synthetic, still smell like plain old oil to me.

But a hydracked oil is suppose to be better made than the original process. So is there any difference between a $1.42 bottle hydrocracked motorcraft oil and a $2.50 hydrocracked syn blend like valvoline?

The used and new oil samples I've seen suggest the motorcraft has the edge. Although I have ran the Valve syn blend, and it did hold up better than valvoline original.

But I installed some Motorcraft today (10w30), via all the good results from the new and used samples. All it said was made from hydrocrack process.

Another regular Maxlife user here. Familiar with that smell. Quite similar scent to Rotella T 5w40 albeit this HDEO is stronger. Gives me that more "viscousy crude heavy dutiness" compared to a pcmo as my Motul.
