Track has a ton of stuff for heavy oil: Mutant, Super-Freak, Phenom,
Columbia has the new Throttle,
Brunswick has the Raging Inferno,
Dyno-Thane has the Vendetta Particle (inexpensive; I have one and can hardly find enough oil for it.)
Roto-Grip jas the Silver Streak Particle & the Fule,
Visionary has the Gryphon Particle, and the good old Granite Gargoyle (Cheap on the internet- $85 plus shipping)
Ebonite has the Jungle Green (cheap), the new V2 Strong (inexpensive), and the Addiction,
Hammer has the Diesel Particle (inexpensive) and the recently discontinued Vicious Particle,
Morich has the Colossus and the Colossus Supreme,
Storm has the X-Factor Deuce.
All should handle a good deal of oil.
