RI A6

So, the initial 3000 mile testing on the Double-Super-Secret Experimental Racing Oil is complete. The stuff that Terry Dyson designed for the RS4 engine and had formulated works. All wear numbers are down to lowest levels ever recorded in an RS4.

Sample points are shown. The curves are Excel fits to the points.

Flashpoint is up to 320F.

Fuel dilution is down to 1.29%, from a high of 2.37%.

Viscosities are highest recorded for 5W-40 Oil in an RS4

100C cSt - 13.3 (low 40W)
40C cSt - 76.6 (high 20W)

These measurements include two track days at Watkins Glen.

I would think that break in and age of motor play a part in the amount of wear, so I'm not sure how valid your results are. Do you have graphs of different vehicles that have used the same types of motor oil all along?

RI A6

Wear decreases after break-in and then normally reaches an asymptotic value of wear for a given oil chemistry and engine design. I cannot, will not reveal everything here, however, these numbers are nothing short of stunning and are quite valid.

The flashpoint number is most amazing. Until 2 months ago I was running fuel dilution twice as high and flashpoints down in the operating temperature of the engine at 235F.

Terry Dyson has designed this oil with some very leading-edge chemistry and additive packages, specifically to fight fuel dilution and decrease wear. These numbers are, in fact, lower than Mike (bhvrdr) posted recently on his S4 with 67K miles on the clock.<ul><li><a href="https://forums.audiworld.com/s4b6/msgs/400442.phtml">S4 UOA for comparison</a></li></ul>

if you had thought about perhaps going back to one of the oils you had used before so it can be a sort of multiple baseline study (ABAB) to rule out natural break in or whatever? Would that make sense to do or is it being neurotic?

Great work!

there are often inconsistencies in oil blends, lot to lot. this has been reported on by consumer groups is the past. in any multiple testing of same oil at different stages, it would be best to have bought the oil being used at one time, one case.

Will we get to buy this or is there a secret handshake only a few will know?

of course it does...at least someone else here is thinking.

I know he means well, but what bothers me about RI RS4's 'reports' is that his 'study' is inherently flawed in so many ways, the data don't even deserve to be reported. It's irresponsible, in my opinion.
