are they ok to use in conjunction with eachother? becasue the throttle body cleaner gets sprayed into the engine, and then the fuel system cleaner obviously gets into the engine and the fuel system cleaner that i have says it cleans intake valves. i doubt they would interfere with eachother but i was just wondering. should i space it out like do the TB cleaner today and the fuel cleaner tomor? thanks guys.

 

it shouldnt be a problem. people that use seafoam pour that stuff into the gas tank, crankcase, and tb all at once.

 

you can do both but do them seperately

 

i'd do them seperate too...not that i really know much about it but just to be safe...it can't hurt to be safe.
