[QUOTE=20774;846239]I started an oil thread...of sorts in the Airheads forum. I have completed testing of 18 oils similar to testing that was done by Jeffrey DiCarlo (1999) and Matt Parkhouse (2002). My results start with this post:
The Spectro products, BMWs, as well as some other popular oils were tested for ZDDP, viscosity, and TBN. I will be submitting an article to the ON soon.[/QUOTE]
Can I bust into my new gallon jug of Rotella T6 yet?-Or must I wait for the results?:eat:laugh
[QUOTE=20774;846261]I've never seen Golden Spectro sold at the dealer. If you mean that the BMW oil is blended by Spectro, then yes, the dealer sells that. But not the straight-up oil in Spectro bottles.[/QUOTE]
I had to double check. I've bought both, by the case. The BMW "brand" as well as straight up Golden Spectro.
However, per my last post, I no longer purchase either, since I'm a Mobil 1 kind of guy now.

Go ahead with your oil...Rotella T6 wasn't on the menu. Shell Rotella T in 15w40 flavor was. It was the only 40w tested. It was so-so on ZDDP...would have been better if it had more. It was pretty good in the other two categories, but I think people are more concerned with ZDDP.
