Indeed, one reason that prompted me to take on a little extra work. My concern was not with the engine oil, rather the gear oil. It is supposed to be GL-4 & GL-5. Being GL-5 it in theory shouldn’t be used where there is yellow metal. However Royal Purple was claiming it was safe for use in transmissions with brass blocking gears. A couple of us Audi guys with very expensive transmissions didn’t want to go on marketing hype. After cornering a Royal Purple rep at SEMA and many, many phone calls they finally admitted it probably shouldn’t be used in a transmission, or at least they thought maybe it wouldn’t be a good idea. There words were something to the effect of, we don’t really know Audi transmissions, so maybe you don’t want to use it. Of course I had just flushed and filled one of my spare boxes with it just a month ago. I hadn’t run that set of gears yet, and thankfully so. I’m going to drain and flush it as soon as I get some more oil in stock. I ran out of what I normally carry, so I have to restock. More details to follow. ---

I love how people will throw “whatever’s cheap” into their daily drivers that get exposed to more miles, harsher conditions, and are generally required to be reliable… while putting $50 oil into the car that may see 3k miles a year and only on sunny days. ---

The DD has been reliable for over 135k miles on bargain oil, only making 90whp has its advantages. I do put more expensive oil in the car that makes over 4.5 times that amount of power with the hope that it will buy my finicky little rotary a few more thousand miles over its already short lifespan. ---
