Why does Wildcat use MORE oil than the competitions fuels?.....
Why do some fuels burn dirty leaving a nasty brown goo behind? This is due to the quality of the castor used. Wildcat uses the highest quality (and more expensive) Klotz BeNol Degummed Racing Castor in which the harmful resins are removed which reduces the carboning, varnish, and glazing.....
I have been very picky about my fuels and I truly think wildcat has a good package going. But thats just me.......
While I won't argue about the quality of the Klotz oils beeing used on Wildcat's fuel, I will desagree with the statement that more oil is better. I think that more oil produces more friction thus higher temp on today's tight tolerance high revving engines.
I can assure you that most Italian manufacturers today suggest 9% total oil content.
The second statement about using degummed castor oil...well most top brands of fuel do so, but what Wildcat doesn't say is how much of the total 10% oil in their fuel is Castor oil....and that is where the difference might be, more Castor more protection to high temp friction loses off oter oils....hell in Europe the top brand fuels almost use only Castor oil...and degummed or not Castor oil will allways live black deposits on the long run, and if the fuel has more off it, surely faster....and there is nothing wrong with it, when you service your engine efter every race you just clean it out...big deal.
The bottom line here is that I would use a fuel with max 9% total oil and the one with more Castor oil in the blend with the synthetic....maybe 50-50.
Now if you ask me what fuel do I use....It's MAXY'S FUEL Clear Formula
