Fuel that really does make a difference …
Having covered around 6000 miles now in my 1991 Audi 100 S4, its 28 MPG thirst for fuel has meant that I’ve visited a lot of petrol stations .. and also filled up with a variety of fuels.
Recently Shell has introduced its new V Power product into the UK market. It’s a 99-RON blend which basically means a modern engine control can run with more advanced ignition. Which means more power.
On top of that it’s supposed to be packed with cleaners, and with lubricants that actually reduce the internal friction of the engine (I’m presuming between the piston and the bore!).
The S4 seems to really like it. There is none of the slight backing-off feeling under accelation that I’d been getting when running with Shell’s previous 97 RON Optimax. It just pulls smoothly and powerfully right round to the redline.
I understand it can improve fuel economy too, but I wouldn’t know about that …
