What do you feed your RS4?

With the imminent arrival of my RS4 next Saturday :biggrin3:

Which grade fuel do you use, Standard or Super unleaded?

Which grade do Audi recommend?

Shell Nitro+ since day one. But then I've always done that with any decent motor I've owned. When I collected mine I spoke to the service manager & he was adamant that a premium fuel should be used. He said the difference you see in an engine thats been stripped is quite surprising.
It's all torque talk.

Super, always. Needs thinking about if you own a garage queen as the super bit quickly becomes not so super if in the tank for a while. However, it's an RS4 V8 so thats impossible if your 'on it' even remotely...and if your not then it's time to get a diesel?!

Well..... I always fill mine with Vpower or at a minimum Tesco momentum 99
However, in the week leading up the the rs246 rolling road day at AMD at the end of last year I'd lent my car to a mate for a couple if days, and his wife, in her infinite wisdom, had filled it up in asda on their shitty 95 Ron cheapo bollocks on the way to mine
I then ran it at the AMD day and it still made exactly the 444bhp that the book claims and I felt no difference in power on the drive down
The only real difference is it seemed to smoke a bit on the rollers

Regardless, I've still used Vpower since

I'm VPower or Tesco too. Normally the former. Supermarket plonk does not have the same additives, I would not want to run a performance car on it.

I'm really no expert, but I think you'll find one tank will make little to no difference. It's has more effect if it's a regular occurance. Using Nitro+ over Asda may have given a better throttle response but I doubt one tank would have hindered the results from AMD that much. It's something that in my experience is often debated on forums & rarely confirmed as very few of us are in the habit of dismantling our engines! However, for the dealer to recommend a certain fuel type when there is little benefit to them is in my mind a pretty strong rationale to go with what they suggest.

Feel free to correct me by all means though...

I agree, as modern cars are so well tuned and adjustable that they can run on most fuels without much discernible difference. After all, can people really feel the difference of 5-10bhp when you have 400+ ? I can't imagine. Maybe a placebo effect makes owners feel it faster than it actually is.
It's pretty well recognised that vpower nitro is the best and that's what I normally go for as it's also the closest fuel station to my house
