Hi Chaps
I am a newbie on here as I am only a dreamer, but very interested in what goes on.
I did build a GT40 in about 1989 but that is long gone.
However, when I was a kid, here in England, about 16 yrs old I had a Lambretta scooter, along with my pals we used to put a little Castrol R on the tank ( 2 stroke engine) and the smell was wonderful.
Found this quote on the internet just now from Castrol
We are often asked about the best way to obtain the Castrol R odour and from our discussions we are aware that many people add a small amount to their fuel. Just how much seems to be an inexact science, but generally the less you can get away with the better. You might like to start with 1000:1 fuel:R ratio (20ml of R in a 20 litre fuel tank) and see how that works, adding more
oil if there is insufficient effect. I would suggest if you get as far as 100:1 (200ml of
oil in a 20 litre fuel tank) and still aren’t getting the effect you want, you might want to re-consider the benefits versus the downsides!
Try some it cant do any harm.
