[doc] Re: Non DeLorean Techical Question

["Paul Reed" <paulreed_email@xxxxxxxxxxx>]

I own an Austin Healey Sprite and it also runs on. It's the petrol. 
When the cars were made the petrol was a differnt octane. Mgs are 
well known for running on. You can buy an anti-runon valve from the 
Mgoc that stops this.
