can i run my everyday mini on this? or is it not a good idea? i read somewhere that it leaves a gummy residue in the engine that needs cleaned by stripping the engine every so often.

help apprechiated, my engine is nearly finished and ready to go in in the next few days.

If you search for oil related threads you will find many on this subject!

Use 20W50 Mineral oil.

Castor based engine oil with the distinctive Castrol 'R' aroma, often used in race Minis in the 1960's but superceded for most purposes by modern oils. Used to make a nice smell in the paddock at Brands though!!

[cityandcolour]

why would it be illegal though?

also, which castor oil do i need for the castrol smell, as this is what i'm after with it

This is what seems to still be available for 4 stroke engines, you need to find out more before using it in a Mini though.
Castrol Classic R40, 4 Litres
A high performance castor based engine oil with distinctive Castrol 'R' aroma suitable for 4 stroke engines. SAE40

"A castor based lubricant which is primarily designed for the racing world; however its unique properties can also benefit private owners interested in high performance.
Never mix Castrol R40 with mineral based or synthetic crankcase oils"

As above once you fill your engine with Castrol R I don't think you can change back to normal mineral or synthetic oils without stripping and cleaning the engine/gearbox?
Some people say a teaspoonful or two of castor oil in your petrol tank will create the required smell!

dont do thiiiis

knew someone who did this and it smells bloody aweful when following them in convoy....and generaly no point really

[LOWRIDERHORNET]

why would it be illegal though?

Because it gives of an smell even though its an nice smell but also it gives of too much smoke unlike standanrd oils so its band for road use

[mini93]

shouldnt smell much if you have decent piston ring seal as thats the job to scrape oil off while lubricating the rings...not to lubricate the the combustion chamber.

still, why not just go for a decent racing oil like valvoline and be glad you dont have to spend £130 a tub

It's not illegal as far as i know. I was passed a few weeks ago on the A34 by a Mini Sprint on the way back from Beaulieu with the distinctive Castrol R smell. I've put a small amount in the fuel a couple of times and you do get the nice smell but it's no where near as strong.
Not really worth running your car on this, especially on an everyday car. It gets quite thick when cold and i believe in the winter you need to warm the oil to be able to turn the engine over and start the car.

Its is illegal

A few of my scooter mates been stoped for it

[mini93]

thats because scooters are 2 stoke...you put oil in the fuel to lubracate the crank and thus they smoke like hell...its NOT the same on a 4 stroke

[LOWRIDERHORNET]

they smoke like hell

They don`t actully

[mini93]

some iv seen do..the fact your burning oil still remains and you cant argue that without then saying your running your engine without lubrication
