Hi all,

We, in the UK, are now the happy recipients of shell V-Power, a high octane
fuel rated to 99 RON. I am interested to hear people's opinions of this
fuel, particularly from fellow CIS system pilots!

I filled up with V-Power and found that I was unable to make more than basic
boost, with very occasional spikes and quick drops back to basic boost.
Thinking there was an electrical fault in the APC system, I checked the
whole system over. Once empty, I happened to put a little 95 RON and found I
was able to make full boost again, albeit with a little knock a high revs.

I filled up on my normal supermarket fuel and my car was back to normal. I
have since swapped my aged Bosch HT leads for "proper" Bougicords and
replaced the distributor cap and rotor arm. Curiosity got the better of me
and I filled up on V-Power to find exactly the same situation. Upon
finishing that tank, I'm now on Total Excellium (rated to 97 RON) and again
have no problems and top boost throughout the rev range in all gears.

Can anyone shed any light on this? APC is reading the situation as "knock",
or that's what my APC knock LED says. With 99 RON, you'd think the exact
opposite would be happening. Is it just that I am unable to combust the
fuel?

I know a C900 8V driver who really rates it, but he has very odd timing to
suit an esoteric Heuschmid cam in his car. What do other stock C900/99T 8V
drivers think?

hmm well I tried a tank of tesco 99 ron in my T16 - felt more responsive at
low revs but boost was down and variable....

sometimes full boost, other times about 4mm shy of red....seemed better
after a 'good thrashing'

I've yet to try Tesco 99 ... If it runs fine, as other 8V drivers are
reporting, then V-Power will be confirmed as a dud for my car. If not, then
perhaps my car cannot handle higher octane fuels ... I'll be looking for
reasons why. I can run Texaco SUL quite happily (I think that is 98 RON) and
97 RON is perfectly acceptable.

Turned out to be my fuelling ... It was miles off :?
At 1.8% CO, V-Power ignites just fine.
