Castrol R in a TR

[Yertis]

The perfume thread over on P&P got me wondering if there isn't any reason I can't put Castrol R into the TR6. Love the smell of course, reminds me of Dad and his karts and bikes. Anyone know any problems with this oil in this type of car?

Do it.
Will be no problem and will smell like 50's GP car.

Not cheap though.
