Well i used to use nonsynthetic oil for a long time but never in my CR because this was way before i had it i used to run it in my old elsinores anyway i mean i never seized one up and i rode a long time on its top end which by the way the guy who i bought it from had replaced and put the piston in backwards! but it still ran ok anyway one day i did decide to run some snythetic redline to be exact and i noticed an increase in overall power it felt smoother and just seemed to rev better and thats when i had become a beilever in snythetic plus i had always heard good stuff about it before personally id never run a non synthetic in my CR ever and actully what i hear is the best oil is castor bean oil but is a very dirty oil build carbon quickly ive actully heard that you can mix a bit of castor bean oil with the oil you regularly use and it will help i have yet to try it
