1st Seafoam Treatment + Oil Change

I bought my GC in February with 100,840 miles. Oil was fairly clean so I've waited till now to change it. Done the 3 step Seafoam treatment Monday and changed the oil yesterday evening. 1st, Monday the carbon release (white smoke) was huge. Then when changing the oil yesterday it was filthy (very dark) giving me notion that the Seafoam done its job there too. The pan plug was a #*%$# to remove. With little persuasion with a pair of Vise-Grips and a hammer it finally came off. Thankfully I'd bought the Fumoto Quik Valve so with it installed the next time should be easier. Used Mobile 1 High Mileage Full Synthetic 5w-20 and Fram Xtra Gaurd filter.
My drive to work this morning (33 mile drive) I can already tell there is a HUGE improvement in my Hemi's performance. Not sure if synthetic was used previously (my bets on no) but the combo of the Seafoam and the synthetic oil helped to quiet the lifter tick some and throttle response was greatly improved. The idle hesitation is completely gone!
Funny thing to share. When changing the air filter I found a dead bird in the air box. Attachment 38955Attachment 38956Brought a song to mind "I wanna fly like a sparrow into your Jeep, Fly like a sparrow let your Hemi carry me". Sorry. Couldn't resist.

Re: 1st Seafoam Treatment + Oil Change

Nice job, I am going to do mine by the end of the month mine is only a v6
how many miles did you run in between seafoam and oil change?
I read it somewhere that it can go as much as 300 miles before changing oil, does it really heart engine if let it run that long?

Re: 1st Seafoam Treatment + Oil Change

I put the Seafoam in on a Monday evening half into the crankshaft and half into my gas-tank with about 3/8 of fuel in it. I then drove two days back and forth to work (140 miles) then changed the oil and refilled the tank that Wednesday evening. I had also heard of some driving 300 miles but also heard the warnings of overdriving with it in the engine and it sludging up. Most say 100-200 miles is sufficient. As far as adding it to the fuel you can have however much is in there. The timing just worked out to where it was nearly empty by that Wednesday evening so I refilled the same day. I will plan on doing the Seafoam treatment about twice a year from hear on out in order to keep the carbon build up to a minimal Good luck bro and hope you get happy results

Re: 1st Seafoam Treatment + Oil Change

I am also sold on Seafoam, as it does the trick on those sticking MDS lifters. Synth oil actually makes no difference in terms of throttle response, it is the Seafoam treatment. In case you dont have a catch can, make sure to get one and clean the throttle body, which makes a world of difference in improving throttle response and mpg.

Re: 1st Seafoam Treatment + Oil Change

i usually do a seafoam treatment every 2 oil changes- and i throw it down the brake booster and in the gas tank. i rarely throw it in the crankcase.

btw next time you do an oil change, id shy away from fram filters.

Re: 1st Seafoam Treatment + Oil Change

Yeah no more Fram from here on out. It wasn't until after I'd already bought and installed it that I began to read about all the flaws with Fram filters.
