Re: Mixing Castrol r30 castor with synthetic oils
Yeah the whole engine feels tighter yet smoother since I started running some in the mix. My theory was that because of the sloppy build tolerances these engines could really benefit with some of that magic Castor Varnish. The head dome has a dark brown smooth coating from the Castor which is as smooth as teflon! I have left it there to boost compression and the stuff on the piston head is pretty easy to chip off. I'm thinking it may well be worth the hassle with all the benefits.
Should I be scared of mixing oils though? some bad reaction between them? The Castrol Mineral I have at the moment has mixed ok in a test bottle and has not changed consistency or reacted in days now.
