I was just wondering if the Curtis Youngblood blend from Wildcat would be ok to use for break in? I know that your not supposed to use castor for fear of messing with the regulator, they use the Benol brand castor. This is what it says about it;

BENOL CHARACTERISTICS: BeNol has a 25% greater film strength, higher load carrying capacity, and reduced varnishing properties than the lower grade AA castors.


Smoke Rating: 4-5 1=Fog 10=No Smoke
Clean Burn: 3-5 1=Heavy Deposits 10=No Carbon
Film Strength: 10 1=Failure 10=Virtually No Wear
Viscosity @ 100 F 950 - 1000 SUS 50W @ 40 C: 220cSt
Pour Point: 0 F
Flash Point: 520 F
Rust Prevention: Contains rust inhibitors
Certification: A.P.I. S.A. Intended for Racing Engines
Biodegradability: 100%

I have about 1/4 gallon of it that I had left and was just wondering if I should just use it for starting fires or if it is ok to use?


Thanks Shane

I don't know anything about this fuel. Sorry.

I don't use Castor. Look under the part where it says Clean burn. This is what castor does. Leaves deposits. Namely Carbon


Running a gallon of fuel is not going to ruin your engine, if its a good quality fuel. I'm sure Wildcat has a good following of people. I have no experience with it, so I can't say.
