"Swepco 503 Fuel Improver" Yeh, or Neh?

[ldl]

Well I was searching the all mighty "DriveWerks" catalog, and I came across this:

So, I'm asking... Shall I? Or is there any other products out there that are similar that anyonbe recommends over this product?
In conclusion... I'm thinking to myself "It wouldn't hurt"... Or am I wrong?

Well thanks for your time fellow Porsche drivers. Stay safe.

better or worse?

[Roger Hall]

Swepco makes qualitity product. I wouldn't use anyhing else in the tranny. As for fuel additives Porsche recomends Mobile 1. I used the Zmax and liked it but the cost it is expensive.

how does it compare to the Chevron F/I cleaner?

[tomeiche]

I used GREASED LIGHTNING 12000 mile petrol additive.cleans everything,but every porsche owner should use ROIL GOLD metal condtioner oil additive.Saved m y engine head from exploding when it overheated without me realizing.It was way into the red.Now i have a slightly smaller steering wheel{astrali}and i can now clearly see the temp guage.Do some engine searches to find info and local supplier.Engine now runs like silk.By the way roil gold leaves no coatings on the engine parts

[Roger Hall]

Sorry I ment to write Chevron.

I must not have been paying much attention writing Mobile 1???????

I tried that and the car behind me got all ticked off when it his his windshield. My question....How does this benefit ME?

JK...I use MM oil in my oil at oil changing time just because I hear it is ok. But, my big question is how do you know it actually helps?

i had an 86 300zx that was misfireing due to build up in the injectors, and i put a quart of marvel in with half of a tank of gas, didn't have time to pull the injectors and clean them properly. i did this as i was leaveing my old job,and had about a 30 min commute to get home.as i was driving i slowley noticed a difference in the performance of the car.when i got home and parked it i left the engine on for a minuit and opened the hood, i had noticed my idle was a lot smoother, it seemed to be running fine. i ate dinner and watched some tv for a while giving the car time to cool. when i went back out side to put it in the garage it instantly started(a first for the car) and put it in the garage. i pulled one of the injectors and was going to clean it and the lower tip allmost looked new so i just put it back and the car continued to run ok. about a week later i used the sea foam in the intake(put a vacume line in the sea foam ). *****very important to follow the directions EXACTLY******. when i started the car the smell was horrible(do it in an open parkinglot, not your front yard, your neighbors will never forgive the horrible smell)the car didn't have a cat(the first thing i do when i get ac car ,but if i get pulled i bought it like that ) and a free flow exhaust and i actually saw small carbon flakes comeing out.the car ran like it had just recieved a major tuneup! that was enough proof for me, i have done the same treatment on every car i have owned and never had anything but good results. all for well under $20

What exactly is sea foam? I've never heard of it.

[guinnastysassy]

it comes in a metal canw/ at twist off top,blue and white. they make one for engines and one for trans(just auto i think) http://www.seafoamsales.com/about.htm

[MikeCT]

So have you tried sea foam in the gas and oil or just through the intake? Which way works best or do you add it to everything?

[guinnastysassy]

just like marvel, you can use it on everything,fuel tank, crankcase and through the intake , just make sure you follow the instructions. http://www.seafoamsales.com/motorTuneUp.htm

I was asking for your personal experience. Thanks though I did check out the site. I'll probably try it sometime.
