[Field Marshal Dr. Opti]

It isn't always easy to find super unleaded 99 octane fuel around here.

Will octane booster work when added to supermarket petrol, or is it snake oil?

[Nick W]

Of course it will work.
But why would you bother?

[Field Marshal Dr. Opti]

Of course it will work.
But why would you bother?

Because my car (according to the handbook) is designed to run on super unleaded. It may be the placebo effect but the car does seem more lively and less sluggish when filled with Shell Vpower or similar.

See, if you had a car that runs on DERV you wouldn't have worry about such stuff!

The highest octane shit over here seems to be 91.  No wonder they only manage about 250bhp from their 6.5l wagons.

It has more veggie juice mixed in over there as well I think?

A 5.0 supercharged, I believe? Feels sluggish unless fed on rocket fuel. You couldn't make it up

Go to Tesco and use there 99.

Used to run my Cosworth on AvGas from the local Airfield, it really liked that stuff. 

God, I really miss that Car now.

On it's knees before 4000 RPM. No thanks. I'd rather eat coal.

It's all relative.

When was the last time you revved anything other than a tiny hatchback to 4000rpm, let alone past it?

Just been having a read about your motor on autocar. It really is something. I would have a permanent semi if I owned one.

Every day that ends with the letter Y.

Not in top gear though as the Tata pulls almost 50MPH for each 1000 RPM in top (8th)

I have  Autocar on subscription. It works out at less than £2 an issue delivered. Cover price is £3.80.

In it's day the XFR was 'a properly quick car '...........  It still feels nippy but car performance has moved on since then.

With regard to your semi I'd rather not dwell on the mental image.
