I wonder if you can get castr R aftershave? 😆 |

I wonder if you can get castr R aftershave? 😆 I chuck about a teaspoon of R40 into the lawnmower. Was told years ago that Castrol R and normal two stroke oil wouldn`t mix. Two weeks ago i put about 10ml of R40 and 10ml of Full synthetic 2 t in a small pot, still mixed nicely. This may change if you run the R mix through an engine, have heard that burnt R residue can turn acidic if left for a while, not good for engine internals on an infrequently used bike ? Put a drop in the LC tank when I knew it was going to do a lot of miles , and was getting a few tankful's of fresh super before it was parked up for any length of time. |

Castor Oil (not Castrol) works for me. Egg cup full per fill up with petrol.

Castrol R and minerar/synthetic oil don't mix, but that's in a tank. Sure its OK if its in petrol

The road racing boys have been using home brewed fuel mixes involving castor and mineral oil for years, but they do strip, clean and replace parts frequently.

Ahh, i used to own a hilux that ran great on veg oil, anyway i once used a petrol can that had remnants of veg oil in ( virtually none) and used it to fill my ktm 300. it smelt great but gummed the rings so they stuck in the piston forcing a top end rebuild . ill not be risking it just for a nice smell.

Never understood the obsession with wanting to mess with the fuel mix of a bike that already you ride with two fingers over the clutch, but hey what do I know lol If you like the smell dont they do a candle? www.ebay.co.uk/itm/193770743309 |

I believe Blendzall makes a synthetic castor oil that smells just like the original and can be used in injector pumps  |

I have used Maxima Castor 927 in my enduro 2 strokes for the last 17 years. Never had a problem with it at 40:1 and it doesn't gum up the carb if you don't drain it if it's stood for a while.
A word of warning though. Do not run it through the autolube system, it will have to be premix.
Like the comments earlier, putting a bit in the tank should be ok as the castor and mineral oils will only mix in the carb just before combustion. Castrol R used to always separate from the fuel that's why we had to shake our bikes before we started them (I still do that now! Old habits).
You can't beat the smell, I still get comments, especially from the old boys.

Just enjoy the smell 👍🏻 I just dont get that bit either.. but hey each to his own. You can get strawberry 2T oil as well   Always amuses me that people 'put a bit in' their tanks, lowering the fuel content in the fuel air mix. Hope they upjet accordingly? |

Exol full synth 2t and R40 mixing quite happily in a jar, but only two weeks into my test. Does it not separate into 2 levels of specific gravity? Yes separated out, but stayed liquid, no apparent reaction between the two. |

You can't beat the smell, I still get comments, especially from the old boys. how does pre-mix and injector two stroke oil differ ? Premix oil is a slightly thicker heavier oil specifically designed to mix freely with fuel in a tank or a can, injector oil is thinner and easier for the pump to push to where it is needed, it still readily mixes with the fuel air mix. There are various trains of thought as to which is the better of the two methods, in race engines castor based oils are frequently used as castor oils provide higher lubricity than mineral oils however castor based oils require more engine maintenance to prevent rings gumming up and deposits forming inside the engine. The best for a roadgoing bike in modern times is the modern fully synthetic 2 stroke oils run through the oil pump. These provide the highest protection and lubricity for the money and are cleaner burning to protect the internals of engine and exhaust as well as the environment..(Did I just say environment)   |
