Hey everyone just got my fc up and running! I have a bottle of lucas upper cylinder lubricant and fuel injector cleaner and was wondering if using it on my next fill up would hurt the engine? Thanks for the help (true rotary noob)

 

Snake oil. All additives are snake oil.

If you want to clean the injectors, have them professionally cleaned/tested at an injection.

 

I use Seafoam on the Rotary, Lucas on the 96 Boinger...
