Caster Oil Question?

[bluejets]

Yes, well, that may be but the reason for the post was to show the brand etc.
There are most likely other suppliers with a lower retail price.

Example ...... https://www.campbelltownhobbies.com.au ... -5-litres

So all you need to do now is sort out your transport.....

Sorry, thought I had shown or mentioned the supplier I have been talking about, here is their link "New Directions" https://www.newdirections.com.au/epages ... s/OV5KCAST a skin care company, and the price for the 5 litre bottle comes out at $13.64au a litre.

All the suppliers mentioned in this thread are close by, a 20-to-30-minute drive from my place, for me price is the deciding factor.

Well, if anyone’s interested, I have 2x sealed gallon cans of Castro’s M left, £40 a tin, I am in North Manchester, OL4. Drop me a message on alancantwell47@gmail.com

I'm sorry, but I have to totally disagree about castor oil. I've been running ALL my engines - ancient and modern - for decades on fully synthetic, and never had an issue.

This includes Cox .049 and 09s, Webras (the German made ones, not the later Austrian ones) Hirtenburgers, HBs, OS, Super-Tigres, and on and on.

Some of these are ABC, but most are ringed or plain pistons.

They all thrive on good synthetic (Klotz Techniplate - NOT Super-Techniplate, which contains castor, sometimes with a trace of EDL added).

They stay clean, don't get varnished up in hot environments (helicopters) and show no signs of wearing out anytime soon.

Castor can and will cause varnish build up inside as well as outside, which leads to worse heat dissipation.

Back in the early 70s, I used to race Karts (class 4 standard - 200cc Villiers 2-strokes, capable of about 110 MPH flat out). Ours was the only team in the club NOT running castor. We were also the only team to regularly get through not one, but two seasons without a single seizure, and I only recall replacing a piston once!

The other teams were getting through two or three pistons every season.

'Nuff said!

I'm with Pete, in our case 2-stroke motorbike racing, how can a laxative possibly compete with a properly engineered, highly developed and specialised lubricant?

Yes, well, maybe, maybe not, but I'll be staying with castor.
Used it for nearly 60 years now and result of preservation of the engines is undeniable.
There are many factors why your "go kart" engines may or may not bugger up but the arguement cannot be placed on castor being unreliable or insufficient for good lubrication, there are too many prooven cases against.

Use what you will but I'm with castor.

I'm with Jeff, used castor for over 50 years, never damaged an engine diesel or glow, 2 and 4 stroke, I will stay with what I know. Anyway, the synthetics on the market sell for twice the price of castor, that's here in Sydney, not sure the castor prices around the rest of the world. The only synthetic I ever used (in the late 1980's) that I would have continued to use today, dropped off the market when the company changed hands.

I have now used this "refined castor oil" for two months now, the OS15 loves the new fuel. Running 20% castor, 10% nitro and 70% methanol, and I don't miss the castor oil smell.
