Read up on the Mobil1 fiasco in aviation.

Lost their asses in liability costs would be a polite way to say it.

@Eric: I am in disbelief that something so simple could be overlooked in this discussion. All of this technical talk and it is just now discovered that we are talking about different products.

Oh well. I guess we can sum it up this way then for the average viewer who might be unnecessarily concerned that M1 15w-50 may not be flat tappet friendly all of the time... Silver cap, formerly red cap, is fine. Extended Performance or gold cap GL-5 was not.

I apologize to Eric, Roger, Sean, etc. if I came off hard headed and that offended you. I don't like unproven statements to go on uncontested. I was not aware that you all were referring to the Extended Performance oils. But hey, if someone else happens to learn something from this then it is thread space well spent, right?

First, my apologies for the misquotes. I did not mean to add confusion to this, of all threads!

Second, did you guys actually read the Product Information pdf I linked to? (And docmirror, their selection tool is just more bad marketing- to find the PI sheet look under Products>Consumer>Racing Motor Oil (and Hacker- both synthetic and dyno are there, along with "not street legal".) No, the amount of ZDDP is not on the VR1 bottle, but it is on the PI sheet, for VR1 20W-50 synthetic it is 0.14/0.13 (1400/1300ppm - I have emailed Valvoline to ask for clarification on the use of two numbers- range? test? haven't heard back yet). That's about as clear as I can get it.

The Valvoline VR1 is really good stuff. You can actually hear the difference when you switch from ordinary Castrol GTX 20W50 (Valvoline were out of stock for about 3 months out here in the sand pit) to Valvoline VR1. Engine runs smoother and sounds better. I reckon the VR1 must be up there with the likes of Royal Purple.
Out here it would cost me around $350 to do an oil change with Royal purple, so it doesn't make sense in my mind. VR1 is my preferred.

well now we are starting to get back to the original thought of the thread

Seems to be the direction of how it went

depami

I tried.


Yes.

I realize the ZDDP percentage is on the data sheet. That’s why I said their site “has full info”. When I said it wasn’t listed, I meant on the label.

The two numbers are Zinc/Phosphorus.

So, you didn't use the selection tool, but gave a link to it in this thread. Other 928 owners may use that tool and come up with the same thing I did, and use the wrong oil. Then here I come trying to correct this and get corrected by someone else who didn't use the tool to select their oil choice either.

To close this out; 1) Don't use the selector tool for the 928. 2) VR-1 20W-50 'racing' oil is fine for the 928. 3) Don't use the VR-1 "Racing" (real racing oil) in the 928 unless it's tracked or has no cats. 4) It's a cool color.

docmirror

Yes I did read it. Denny brought up a link and it did not lead to the correct oil. Subsequently, he advised he didn't use the tool, and doesn't use the oil the tool recommends(lucky).

You brought up VR-1, which I said is a fine oil, but is not called out by tool. I'm trying to keep others from going off the reservation and using the wrong oil in their car. Which leads us back to apples and granola bars.

Offended? Us? ....... just a typical day around here

Kibort should be here soon, then we move to DEFCON 5.

In all seriousness, I do thank you for the discussion. All of you.

Thank you, Ed, for your blessing to allow it.

With this and your following post I am in complete agreement! The only thing left unclear to me is why the Valvoline web site is so badly organized, to the point of being, as you point out, misleading. And other oil company's sites are not much better, often worse. Dumbing down messages to consumers, assuming they are of the same intelligence level as they are, seems to be the modern marketers' sense of their goal. End'o'rant.

Marketing 101 - cater to the lowest common denominator.

The best sales person knows very little about a particular product, their only job is to say just enough to convince you to buy.

Yes there are a few exceptions, selling motor oil isn't one of them

Need an example? Picture Kibort selling motor oil at Pep Boys or Greg Brown on a used car lot.

And so ends another informative oil thread! Somebody else's turn
