[GreenKeys] Lubrication question.

Sun Sep 13 12:45:46 EDT 2020

Scott,

Well link I posted shows a picture of a very modern looking bottle of
Castrol "R" Castor Based Racing Oil and it appears to be in stock at £14.00
a bottle.
Its also listed as current product on the Castrol UK web site:-

https://www.castrol.com/en_gb/united-kingdom/home/motorcycle-oil-and-fluids/
motorcycle-speciality-products.html.html#tab_power1-r-40

so it is still made , I assume its mainly for historic machines. I must
admit I was a bit surprised to see it pop up when I googled it and yes it
does have a distinctive aroma.
As you say most of their product range is of course traditional mineral,
semi-synthetic or fully synthetic oil, although of course the later two are
normally made from "mineral oil".
