Im curently some semi syntec premix oil. 100:1
But i wonder if the Royal Purple Two-Cycle Racing Oil really make a difference on the lubrification, carbon deposit, and performances.

Anyone using it, or have any comparaison chart?

 

im using it and it seems to work great. I haven't had an engine apart yet though.

 

hummm, ok tnx!

Any other output?

 

i cant imagine anyone doing a test on '2-stroke in a rotary' like the tests done on conventional oils in engines. i might like some input, preferably multiple tests, regarding wal mart brands (or similar) vs royal purple (and/or similar).
whats the royal p cost per 16oz? i bought the wal mart stuff for $1.30-$1.80 per 16oz (its been a couple weeks, i forget the price).

 

heh, you shouldnt! unless i was ill-informed (or misunderstood which i dont see how i could have), the first rotaries (dont know which ones exactly) didn't run oil injection. so with their older design (not sure what effect that had), older seals and lack of oil injection, they still ran awhile. i imagine any (proper) oil in the engine has gotta help in that respect.

 

Its ungodly, like $7-9 a quart. I bought their syn premix and motor oil a couple years ago, wayyyy too spendy for an fc owner....

 

I've been running Castor 927 in my 87 turbo for a while and it loves it. I dont drive it much so i dont mind buying it plus its what i run in my 89 250R.
