hey guys - just gone through my first tank of gas (00 se 5 speed) and I've used those fuel system cleaners or gas additives in the past, I was wondering which you guys prefer?

btw, I'm only @ 45000 miles so I don't expect to see too much improvement, but I figure its probably best to do it right

 

I only use Chevron Techron Concentrate (not the Chevron Progard, which has a lower concentration of Techron) in my Maxima. Redline SI-1 has also a good reputation. BG 44K is expensive and hard to find but some people swear by it.

I stay away from the cheap stuff (STP, for example). There is a lot of stuff out there that may cause more harm than good...

 

techron concentrate here too...

 

yea, I think i've used that - Also I do remember hearing scary things about STP products, ruining seals and cylinderwalls....

 

SeaFoam

 

BG44k is the best fuel system cleaner currently available.

 

BG44k - a shop that uses it will usually sell you a can, but it'll be pricey...probably not needed at 45K

 

Do you guys actually notice a difference with these cleaners? I threw a bottle of the Techron stuff in my max at 68k and can't say I noticed any difference.

 

You will only notice a difference if your injectors are clogged. I use BG44K as a precaution every 10k. My first experience was in a 1989 Hyundai Excel. My car wouldn't go past 60mph, would buck, knock and ping. I tried at least 3 different fuel system cleaners and none did anything. I was at a Toyota dealership with a friend and asked the parts guy what I could do and he handed me the BG44K. At the time it was $13 which in 90 was very expensive. It absolutely cured all of my problems and they never came back before selling the car some 30k later.

 

On a whim, I went to Napa and bought a bottle of Seafoam. The guys there swore by it. I sucked about 1/2 can into the vacuum system and really didnt see much white smoke at all--which I attributed to having clean injectors. Well after letting my car sit for a day, all I can say is wow. I noticed a HUGE difference driving to work today with my throttle response, as well as an increase in gas milage. I'm now a convert. (Dont mean to hijack this thread into another Seafoam thread...)

 

Now I just wish I can buy Seafoam in Vancouver.

 

If you suck Seafoam through a vacuum line, it doesn't clean the injectors. It cleans the carbon buildup in the combustion chamber. You have to dump it in your fuel tank or use a machine to force it through the fuel rail for it to clean the injectors.

 

You know, I didn't even think about that. I guess I'll throw some in the gas tank now.

 

Do not put it in the gas tank! It's not an injector cleaner. How you already used it was how you were supposed to.

Oops, my bad. I was thinking this product actually foamed like another one I'm familiar with. I didn't realize it was a liquid. I guess I should have done some more research before opening my big mouth.

 

No prob When I first saw the name a few months ago I thought it would foam up too
