Shell V-Power Fuel launches

[gsb876]

Filled both the SLK and the RX7 up on this last weekend,

SLK actually you can notice the difference alot smoother and more responsive, not to an amazing amount of course but it is noticeable :Ladys-man

The RX7 feels alittle smoother otherwise no real difference but then again the carbon eating formula is the reason we use this more than the power stuff.

The sales dude at the shell garage though knew nothing about V-MAX ie the ron rating or what it does just said "its supposed to be better than optimax" ??

Anyone know if the ron rating decreases over time as with the optimax

There was a chap who posted on here that he had left his car for some considerable time and when he used it again he noticed that knock was pretty much the same as before.

Does anyone know how long it takes for the ron rating to decrease?

I take my car out once or twice a week and used to fill the car up when empty but since I heard this I just put 20 quid in a time - but then you run the risk of always feeding any crap at the bottom of the fuel tank through the car.

What am I best to do? Fill it up and risk the ron rating decreasing, or just putting fuel in as I need it?

Thanks.
