Double-Super-Secret 5W-40 Audi RS4 Racing Oil

Well, most DI engines are hard on oil. Check out some of the Mazdas that also use this technology. The only other VAG engine that is hard on oil is the 1.8T, which has a turbo and a design flaw in that it has a small sump. But you can pretty much run almost anything in the other engines. As for Toyota, it wasn't long ago that their V6's sludged unless you were very precise with your maintenance schedule and oil selection.
Interesting. I was looking at Summits online catalog for some Redline gear oil, and there were 2 footnotes for the product:
(3) The part is classified hazardous.
(4) If you purchase this part, your order can only be shipped by ground.
And in their shipping FAQ is this statement:
"There is an additional $21.00 charge for hazardous materials shipped by Ground; these items are noted."
Whoever is in charge of classifying the products they sell as Hazmat is wrong. Unfortunately, I'm guessing they wouldn't even listen if somebody tired to explain it to them anyway. Regardless, there is a certain online oil shop that specializes in Redline and doesn't charge a Hazmat fee. Plus, IIRC, their prices are better too.

Why are you being so secretive about this "certain online shop"? Gimme the name!!!
you aren't allowed to publicize an online store that sells oil unless they are a board sponsor.
ah well I pm'd him so hopefully he'll reply.
Yep, against the rules to post retail links to non sponsors

What was the last API spec that had a similar amount of zinc (and other AW additives) as RLI 5W40? It wouldn't both me to run a non-API oil, but I am concerned about catalytic converter life.
Oil is not hazardous material.

Hammer I shot you a private message about the place. Could you respond?
Thanks

My cost for RLI in a 5-gal pail shipped comes to $9 a quart from Ohio to S California. At least I save the sales tax.
I replied back...not sure why you don't have it

I posted this picture in another thread, but for the record I thought I'd post it here, also.
My engine has been running 5W-40 BioSyn for over 15K miles. During that time it's seen 10F to 105F ambient temperature, local stop and go driving, multiple cold starts during winter days after full cold soak, long trips during the summer at 105F, and 5 hours of track time at Lime Rock and Watkins Glen.
My normal engine oil temperature ranges between 212F to 235F on the street. On the track the oil temperature ranges between 250F and 275F when the engine is under severe stress under full horsepower at 8,000 rpm. UOAs show no oxidation, no soot, no viscosity shear beyond the initial shear, no additional acid formation, no combustion problems or deposit formations. Finally, visual inspection of the cam shaft through the oil fill shows no varnish buildup.
This engine has 31K miles on it, with the last 16K miles of runtime on the engine using RLI BioSyn. The current oil has been in the engine for 5,700 miles and just came back from 2 days at Watkins Glen. Iron wear rates (not just ppm levels) are running 2x to 5x lower than Audi 502 approved oils, and have been continuously since BioSyn was introduced.
Here's a picture of a cam lobe and mounting block taken through the oil fill in the valve cover. Note, the valve cover is a funky yellow plastic composite.

It's made of some sort of plastic resin composite.
Wear is pretty much identical, but viscosity is higher.
e35'n, Probably not. It is currently part of testing to provide potential oil tweaks to reach 10K OCIs. Summer was a good time test, since there was no risk. I have some different tests slated for the winter months.
