Hi Jon the  castrol 747 when it burns it smells sweeter I have been told that\'s why the rotary boys use it.
I some times use shell 2 stroke that smells like burnt oil
Me and Aston now use royal purple but bit more expensive.  
We like to look after our rotary engines.
Check Essexrotary.co.uk. I think its on his web site.
I can\'t comment on  any cheaper makes not used any.

just been doing some research.....Royal Purple is completely ashless! Ill check out Astons site!

[mikey-t]

protekr is another option

Just stumbled across this. I am thinking of running premix on my 20B conversion as I cannot get OMP control via my ECU and a standalone controller is quite pricey and I am a little worried about reliability on that. Can you give me some first hand advice and experiences running premix? What ratio are you mixing too? There seems to be a wide range of answers on forums!

Cheers

Theres good info on the essex rotary site. But you need a ratio for premix only which i dont know the answer....prob best phoning one of specialist. Or suspect somebody will be along soon on here.

[leeroy_25]

Oh.. Are you running premix as well as stock Omp? Or through a Reservoir on the stock Omp? I will find the answer. I had a ratio already. Was looking for a comparison. Don\'t want to crash your thread.

No worries mate....im running premix as well as omp. Just some extra insurance.
In your scenario your gonna defo gonna need the right ratio...but at 17 quid a litre i was looking at alternatives. Hence the comma stuff.

Prob gonna use same amount as you as got 4 rotarys to supply for!

[leeroy_25]

4 rotaries! Gluten for punishment.. Do you really need premix if you still have the Omp working?
I think I found another one that was around the Comma price as well.. Otherwise it would start getting quite pricey!

Yeah mine the wifes the nieghbours and the race car!

Been doing alot of research on the classifications of the oils!

3 series 1 rx8 engines known to not feed oil to centre of apex seal and  1 r3 and jury still out on it!

Using a747 at mo in 1litre bottles. Want to buy in 5 litre and save that way....

[leeroy_25]

This any good to you?

One thing I found reading around on this is people only seem to recommend using synthetic??
Look slike the cheaper options are always mineral? The above one does not state so I assume it is mineral?

[boosted]

Done a shed load of reading and confused the hell out of myself!

sticking with A747 at mo ! til stocks run out. If i can find in 5 litres then prob stick with this and save that way.

[leeroy_25]

It\'s a tough call when you read so much different stuff! I found another one for £30 and 5 litres.. Think it was on ebay. Will have to find it again now! I think it seems like a good reasonable price from what I can find.

[boosted]

Well i ended up in a 2 stroke performance motorcycle forum and will be sticking with A747.
 
The cheaper end of the market fouls the plugs and ceased solid some of the motors.....its cost alot for a reason!
