As title says , I'm going to be converting my lovely LS1 truck over to running on used french fry grease ! CAn't wait to have that delicious smelling exhaust ! They say it smells just like frech fries or whatever else it was used to cook with . Maybe I'll go out back and rob the grease trap at the doughnut place too . What would you guys rather have - french fry exhaust or Krispy Kreme exhaust ? I'm afraid that if I use Long John Silvers grease that I'd have too many stray cats hanging around under the truck because of the shrimp and catfish smell .Course , all you guys out there in the the land of tex-mex might like to burn used flauta grease . To each his own ! Wonder if Allen can come up with a special "frygrease" tune for me ! All feed back appreciated as usual ! http://greasecar.com/
