Thread: Seafoam Works

In many cases when you clean out an engine with any "flush' it just washes away the sludge that has been attracted to, and blocked out, developing leaks in seals and gaskets. Any engine will get leaky with time. Sometimes it seems like the sludge is all that holds some engines together, lol. I used to own an 85 300zx and used the NAPA brand flush, CRC I think, and soon after it popped a hole in number 1. Don't know if that caused it, but the timing of it didn't put my mind at ease. It leaked like a sieve after to.

that is what I should get I think. If I push it I can see 280-300 but not over. I am thinking maybe a new O2 sensor. I think the car set for a while and never was drove, also never saw premium fuel on a regular basis until I own it.

Of course, I drive 80-90 every where I go so that might do it.

I would think so with the nx gearbox you are revving pretty high at 70 already, 80-90 isnt going to even come close to yeilding the best fuel economy. If you are that worried about fuel economy just slow down a bit on the highway.

Before I turbod my car I was getting about 380 per tank. Now, I'm lucky if I get 290.... lame.

^^^gotta pay to play man...

nitrous cleans your motor good too

you can also run the seafoam through your gas tank to clean out those lines and your injectors as well as add some to your crank case to help clean the rest of the motor. make sure you change your oil within 1000 miles though. and make sure you run the car almost out of gas and run it with 93 oct

Haha Amen to that!

Not true at all. A properly boosted car should become MORE efficient, not less. I went from 29mpg highway to 34mpg highway when I went boost.


I have used seafoam on a few cars, it does seem to work well.

i'm getting a average of 130 per tank I can't seem to find the fukkin problem it has a new o2.new fuel filter,sparkplugs were changed 15 k ago,cap an rotor and im using no air filter. this car is making me broke if anything and it's all stock.

I actually was getting 34mpg hwy on my boosted 190k mile b13 as long as I didnt go into boost to often......

Now though 230 a tank n/a but I never see the top of third... City driving 100%
