im happy this post came about. Im at 125k and i dont know when the last time my car was seafoamed so I need to do this soon but im not sure what the process is.

 

i put in half of whatever fuel i was going to put in. so in my case, i put in 8-9 total gallons. i then put 4 gallons of 91octane in my gas tank and then dumped like 2/3 of the seafoam contents into the gas tank. its kind of a PITA due to how it goes in. i had to keep useing the pump handle to push the little door open to allow the seafoam to enter the tank. i ended up spilling a little too. otherwise, i added the rest of the fuel afterwards so that it would mix well and then started the. better be working
