Castrol R

[The Prophet of Doom]

Has anyone tried using Castrol R in their fuel tank to make your bike smell like a speedway bike?

I found this on another forum...

I have e-mailed Castrol to ask whether or not the sweet smelling oil 'Castrol R' can still be purchased and be used in modern bikes, I have pasted their reply below. What I would like to know is if anyone has added it to their petrol without any problems and if so what ratio they used, thanks, Joe.

I can confirm that you can still purchase Castrol R as a SAE 40 grade oil. Castrol R 40 can be obtained from Castrol Classic Oils (Tel: 01954 231668 or see the link on the Castrol.com/uk website) or one of their distributors.

We don't really recommend it for use in modern machinery because there are more suitable modern oils available such as Castrol Power 1 Racing 10W-40 and Castrol Power 1 GPS 10W-40. The oil change guidelines for your machine will be calculated based on the use of a modern oil such as these and it is difficult for us to give accurate advice on what frequency of oil change would be needed if you were running on Castrol R40, but it could be as low as every 1,000 miles.

Castrol R 40 is a very good lubricant under certain circumstances, however it is relatively unstable and will therefore tend to promote the build up of deposits in your engine. It may not work perfectly with your wet clutch either.

The instability of Castrol R means it is also not recommended for long term storage, so if you were going to store your bike for 6 months, we would suggest you consider filling with new Castrol R at the start of the storage period and draining and replacing with new oil at the end, before using the bike again. If storing for longer than 6 months, it may be worth switching back to a modern mineral, part-synthetic or full synthetic.

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!

Any thoughts?

I used methanol in my speedway bike to make it smell like a speedway bike. ::)

Castor oil is highly carbonizing, will coat your combustion chamber with shiny black (carbon) surface if you use too much in your fuel.  I used to run Castrol R 30 in my 2 stroke racers and can attest to the black coating.

In a 4 stroke a couple tablespoons in a tank of gas will give you some "scent of glory" to your exhaust.

I was thinking about mounting a small 2 stroke APU on the Vision. My first thought was to turn a starter drive with it eliminating issues with electric motors and their inherent problems. Now I'm thinking why not have it do double duty and turn a generator as well? It will run continuously in this role and could be fed with the sweet Castrol R elixir at 16:1. Imagine how pleased the other motorists will be when they come upon my exhaust trail.  :) Or not.  :-\ 

The smoke may be dense enough to obscure my image on traffic light cameras so there's that too.

Just kidding!  :)

Or am I......  :P

 Castor oil, yuck, you don't want that stuff anywhere near a internal combustion engine, two or four stroke.

While it is a fair lubricant it's also a great way to glue the rings to the piston.

Oh yeah, I forgot about the rings too.  All that carbon has to go somewhere!

The two redeeming qualities of castor oil is that it smells so good when burned in an internal combustion motor, and that it is drawn to heat instead of being repelled, which is why it was used for racing in the first place.

Castor oil can make a real mess if not contained and cleaned up if spilled.  On the outside of a motor it turns into a varnish that is very difficult to remove.
