Does PAO content matter?

It was nothing to do the oil's labelling.

My comments were more to do with how I was 'set up' to do what was a crazily impossible task by someone who over-promised what could be achieved for business that was massively overstated by customers who should never ever have been trusted. As I recall he also whinged at how much I spent (but only after I'd spent it!).

I likened this program to trying to turn 's**t into sugar'. I did, with a lot of ingenuity & employing every formulating trick in the book, get to The End but this was one of those jobs that should never have been started in the first place. In retrospect, I wonder if he deliberately set this up to see me fail. Envy, malice & spite have no place in the workplace but in my experience, it's all too common.

Gotcha. So other additives including ZDDP, MoDTC, VII polymers, etc... are competing with the detergent package. I guess this is what's meant by a "balanced formula." Thanks.
 
I see. Still no specfics regarding the chart. Nor anything why group III is so inferior group III based blends meet some of the toughest specs.

I didn't quite say it right. A motor oil is "Base Oil" + DI + VM + PPD to be more accurate. VM=ViscosityModifier, which thickens the oil when hot; & PPD is Pour Point Depressant which tries to prevent waxy crystals from forming when cold. The DI has the FM (moly, tungsten, OFM), ZDDP, detergents, boron maybe, corrosion inhibitors, dispersants, etc., the real vitamins of the mix. PAO, GroupIII, esters, etc. are in the base oil.

It looks like the above, being 100% PAO with a little ester, is what Ravenol typically does, as most Mobil1 oils mix PAO with GroupIII, and it works well. Note the low NOACK in the all-PAO/ester stuff though. The 5w30 has a very low NOACK.

You may think that is silly, but when it's your engine knocking and all you had to do was quiet it was to use a saturated group 4/5 oil, then you would understand first hand the benefits of this formula, and when you add the fact the uoa's are killing it then it gets even better, and now add that to the tendency for these engines to eat up cams/lifters at 70k-100k miles, you understand why we are researching lubrication and are searching for answers to protect those engines.

Taking that all at face value, which I do, you should spit an equal amount of venom at Chrysler as you lavish praise on Red Line. After all, it's not an oil issue; it's an engine issue.

Beautiful! I wish other brands had shared such as this to the public. Thanks.

Note this system DIDN'T need ester to pass seals & I was very happy to leave it out. The DI was extremely skinny (anorexic?) & it was a minor miracle that I got the oil to squeak through all the tests it had to pass. The thing I learnt from this program was that all Business Managers are lying, two-faced idiots & should all be drowned at birth.


Zing!
