so i've been doing alot of research and what not on this forum and thanks to google about Seafoam. so i used it today. 1/3 in pcv valve while idling car, 1/3 in gas tank, 1/3 in oil. yes there was a TON of white smoke from what i read this is normal. white smoke everywhere drove it white smoke. yada yada.

anywho 15-25 minutes later i decide to really drive it. so i take it out. it felt like i kick the engine and it was crying. the car felt heavy like it was a huge effort just to get to 6k . as if the engine was about to blow up if i took it any higher. it definitly felt very very sluggish and just freaked me out.

anyone have any idea why my car is running dramaticly worse?

 

Are you sure it's completely flushed out of the system already? No CEL?

 

no cel! idk been idling all together for good 20mins and drvien it for 10. its got a good 30mins of engine running after its all said and done. maybe its cause its in the gas?

 

How's the engine sound? I've read plenty of Seafoam posts where too much was in the engine and they bent a rod.
How full is your gas tank? 1/3 of a can in an empty tank might have a more dramatic effect on your car.

 

i put it in at 1/2 and then i went and filled it up to top. the engine sounds well great. its super quite. sounds smooth.

 

did you not change your oil after putting in the seafoam?

 

i just did it literaly today. so no. but i think it says to drive it for a day or two then change it. not exactly 100% positive.

 

I always though you had to change it immediately afterwards.. I could be wrong though.

I was always to afraid to put some in the oil...

 

being easter i'll have it changed asap on monday. but i cant imagine it slowing down the engine. maybe because it pulled up all the carbon in the oil the oils alot heavier? its still smoking several hours later after work tonight. and its getting a little better. but still.

 

plugs loaded up?
