V12V fuel grade ?
Discussion
What fuel grade are you guys using in your V12 Vantage engines?
The sticker behind the fuel flap says to use super unleaded, but I have read that there is no performance or engine health benefit, as the engine was designed for ordinary unleaded. There is a £7 or £8 difference per fill.
I only ever used super unleaded in my V8 from new.

If they state super unleaded then that is because the ECU is set to that, no doubt it will run on unleaded but with poor performance and with a risk of engine damage.The sticker behind the fuel flap says to use super unleaded, but I have read that there is no performance or engine health benefit, as the engine was designed for ordinary unleaded.

The V12 does not have knock sensors and is tuned for 95 octane. Im sure it was Bamford Mike who posted this information.
Sure the additives are nice but you can get these in any decent regular 95 octane unleaded such as shell. Buying Vpower is a waste of time and money in the V12 - not the case in the V8V however!

Here you go - 2nd posting down on the BR advice thread.

I'm only asking, as I believe I have read some where that the V12 has no knock sensor technology, as is already confirmed in this thread. If so there is no benefit and it's only a waste using the better fuel.
Yes, good point.My Noble was the same, it was tuned for 95, so nothing to be gained from using 98.
Do you use cheap oil too? 
You get no performance benefit as no knock sensors but the fuel is often better quality (if you use Shell) and the additives are a good thing. For a few quid a tank, it's worth it, to me at least.
My V12 has has the timing changed so it runs on Super Unleaded only.

I'm not sure if it's true, but someone told me the other day that supermarket fuel is only cheap because they buy it off the big brands (i.e. Shell, BP etc) because it doesn't meet their standards. I always get BP Ultimate or Shell V Power.Not sure I believe that George
Both my V8's have been run on what ever I can lay my hands in in remote parts of Europe
Neither of the engines are highly stressed engineering master pieces that have very specific fuel requirements
That is also part of the reason I have found no benefit from 98 RON in either of mine
Now Yetis monster is a different animal

Supermarket fuels will always contain slightly higher bio content, as will some of the majors lower end product. They will also be co-mingled at tank farms with other non descript (but still on spec) product. The majors will have slightly higher flash points, lower bio content and increased additives in their top end products, as well as a slightly more favourable specific gravity.
Most of the cost in top end fuels is not the octane value, but the density and additives. If you were to have 95 octane analysed, you would be surprised to see the results often come in at 96/97. But it will be missing the additives.
My take - stick to majors but buy the basics if you have a V12, and fill up every 5th/6th tank with super just to flush through and benefit from the cleaning agents.

I'm very interested to know how you did this? Via a dealer? How much was it? Does it improve performance/drivability/anything at all?You get no performance benefit as no knock sensors but the fuel is often better quality (if you use Shell) and the additives are a good thing.
