so i have a friend who goes to one of those vocational schools and he just told me that one of the reasons rotaries dont last as long is because the owner doesnt clean out the carbon from the motor. honestly im not all that great with these types of things and im still learning alot about rotaries and 7's in general. but i was wondering do these things like atf and seafoam(i think thats what he said) actually work? or is it bad for the car??

 

I run a can of Seafoam through the tank every couple of months. Try it, you'll feel an immediate difference in power output.

Stay away from ATF (Automatic Transmission Fluid).

 

i like to use seafoam on a monthly basis in my 7's. if i have and engine that is out of the car and i'm trying to get it decarbonized i like to use marvel mystery oil.

 

Love the seafoam method.
