What type of petrol is best for a Vantage

[revs88]

Hi all,

Has anyone noticed any differences between using normal unleaded and the super/ultimate varieties with the Vantage?

- apart from the extra cash spent at the tills.

Thanks, Richard

Out of habit with my cars I tend to just use super regardless.

But have had to put the odd tank of regular in and don't recall issues.

No issues at all. Fed both the MY06 V8 and my current N400 exclusively on regular - just not worth the extra cost of super for the potential small performance increase IMHO ....

Is the AMV8 not similar to my old 911 where the engine retarded itslef if used with normal unleaded and the power dropped - this was noticeable but if not the case with the Aston no point in wasting money.

Most performance cars do this.

Only the best for my baby, it's V-power all the way. Could be one of the reasons why on a rolling road she was rated at 400BHP at the flywheel, when other Vantages on the same day and same equipment were showing 365-381bhp. I know there could be other factors at play here (new tyres, not a friday car, she never does short city trips, and always gets a good workout), but I was happy. The 10% or so uplift is nothing really. I also run my diesel on v-power diesel when I can get it, and I really notice the difference here, but then she is a 331bhp diesel.

My dealer said not to bother with the super stuff, doesnt reckon it will make any difference on AMV8.

Unless the ECU can adapt or has been remapped then a 1 in 4 fill of V-Power should do the trick. It's not just the octane level, but the additives in V-Power which really do keep the engine clean.

I always use V-Power - but then I nearly always have a remap for this reason.

On a std Vantage, the "super" fuels are worth about 20Nm of torque at peak torque, but on a usual UK day (i.e. cold!) don't make much difference on peak power, as the engine is not detonation limited above 6800rpm. BUT on a warm day, (or a dyno run), super fuels will give you the full power output, wereas a 95ron fuel will drop you maybe 5 to 10 bhp.

Best power / torque i have seen was always on Shell V Power, especially the Euro grade stuff which is 100ron as std.

I'm afraid your dealer is talking out of his bottom.

You'll need Super Unleaded to achieve the full potential in the V8. I know, I mapped the things!

[disad-vantage-d]

I may be wrong, but I'm sure I read/heard somewhere that the super will degrade to the equivalent of regular if left in the tank for a period. Anyone can support or negate this? I'm curious.

That's very interesting, is that the standard map or is there some custom map for the V8. Been filling mine up with std thinking that super was a waste of money.
