anyone know where I can buy castrol r40, or have a link? I can only find stores in united kingdom... any info would be appreciated. Thank you

 

If you're dead set on that, I can't help you so much, but if I may make a recommendation to Benol...that works very well and is synthetic as well. I haven't run the E85 setup very long but so far so good.

I also happen to be in the UK as well so if need be, perhaps I can help get it and ship if for a better rate.

 

thank you very much for your recommendation. Yes, i really wanted a 4 liter container of the castrol R40 but its totaling out to be $100.00 USD just to get it to orlando, FL. =( I think I may just try the Klotz Benol like you said. Seems quite a few people have been running it with E85.
