whats the best fuel injector cleaner for our maximas I am buying some tommarow I would really appericate the help! thanks alot

 

Chevron with techron is gonna get a ton of votes. im sure its good stuff but i have yet to try it although i have it. if you have a local pep boys you can get there calender for $1 and it gets you a free bottle of chevron with thecron, free rainx car wash and free wax as u dry plus a ton of coupons. other than that ive had decent luck with lucas injector cleaner but i dont think it really cleans to well it just makes your gas better quality. iv also used the entire Zmax system and i again dont know how well it cleans but overall i was pretty happy with it.

 

BG 44k, but it's expensive. Chevron w/ Techron Fuel System cleaner is also good. This is the stuff they mix in with the gas that they sell.

Check the "Fluid and Lub" section of the forum

 

I have read many positive comments about both Techron and Seafoam (which can be purchased at NAPA for about $6 bucks). “But” I have never seen any data which proves that this expensive stuff is any better than the many other types of injector cleaners that cost maybe $2 bucks a bottle.

Has anyone actually seen any independent test results that proves that Techron (and Seafoam) is better than the cheaper stuff?

 

I can definitely tell a difference with the Seafoam. I ran a 1/2 a can with each fill and the cars idles very smooth now. Now that Autozone sells it, I pick up a can every time I go there and just keep it stocked in my utility closet. I do plan on using it in the tank after every 3000 miles.

 

I "believe" I can tell the difference too (after using Seafoam). But it's kinda funny that (to me anyway) a car almost always seems to run better after it's washed too!

 

the cheap stuff is almost like diesal........i think that in this aera you pay for what you get

 

I decided to go with Chevron Techron was 5.99 at AutoZone and see how it goes if it does not work as well i will try Seafoam...thats only 4.99..thanks for all the posts and help i really appericate it

 

ohh ohh let us know

 

Pep-Boys and NAPA sells Chevron-Techron 12Oz. bottle for $5.99 a piece usually.

I always get 16 Oz. 4-Pack bottles of Chevron-Techron for $9.99 from Costco here. It comes out to be less than $3 per larger bottle after taxes.

I used to buy BG44K in bulk before but earlier this year they have changed their formula and now it is not as effective as before so I am not gonna buy it at $12-15 per can in comparison to $3 of Chevron-techron.

 

It's not worth buying cleaner. Just have it done professionally.

 

I always thought I am the only one!

 

BG44k is considered to be the best pour in fuel system. Techron works well, but BG44k is only a few dollars more expensive if you shop around.

NO fuel injector cleaner on the market is capable of cleaing the carbon particles on the injector filter screen. In the past I've tried about every one on the market, then decided to install all new seals on my injectors and manualy clean the filter screens. My filter screens on the injectors were at least 30-40% plugged with super tiny particles that got past the fuel filter.


Fuel injector cleaner mainly clean carbon out of the combustion chamber and off the valves by burning hotter. Also, atleast for the 3rd gen max, Nissan says NOT to use any injector cleaner, and that we have pintle-less injectors THAT DO NOT CLOG. The solvents associated with the cleaner can attack the insulation on the injectors solenoid and lead to a failure.

 

I ran it through my system..havent noticed much difference seems to idle better quiter thats about it...

 

just threw in a can of b-12 chemtool ill let you know how it works but it deff is burnin somthing off cause my exhaust is different

 

same stor for me. must be our heads f*ckin with us.

 

Im gonna be Putting "Rislone Engine Treatment" in my car here in a few days. I'll see how that stuff works.

 

Hate to be the bearer of bad news, but Rislone sucks.......you should've just gone with the Techron.

 

I bought a bottle of Redline on Sunday and put in 1/2, then refill up to half tank. I had read some good comment on it, so I figure I will give it a try.

 

I'll try Techron out next after another 3000 miles or so.

 

where can i find bg44k?

 

http://www.bgprod.com/ Look under BG distr. locator. I personally haven't used it since they changed the formulation about a year, year and a half ago, so I can't say anything about it. The old formulation worked like a charm.

 

None.....

 

I thought this applied to 4th gens as well.
Anyone know for sure?

 

My owners manual says not to use fuel additives. The Haynes manual says not to clean the throttle body as it has a protective coating on it that shouldn't be removed.

 

Is the fuel injector cleaner from STP or Gumout any good? I've been using those brands in my other car for the past year after every oil change.

 

The PEA additives (like Techron) should not hurt the protective coating in the throttle body. I won't repeat myself, but you may want to check out my comments on this thread, from Post #29 through Post # 32.

What does PEA stand for and where do you find this information? I just checked the bottles of STP Fuel Injector Cleaner I have in the garage and the web sites but they don't post chemical makeup of the cleaner. Do you just email the company and ask if they use PEA in their fuel injector cleaner products? would it be listed in their msds sheets? hmmm....

 

Did some searching on the internet and I found some more info on fuel injector cleaner products. Here's the link

Fuel Injector Cleaner Comparison

 

Good question. I though that Techron listed this on their bottle, but I'm wrong -- they don't post chemical makeup either. I know that Techron and BG-44K are PEA and that STP and Gumout are not. Sorry I can't be of more help. Later, I went to the link shown above and was advised: "PEA is what's in Gumout Regane. Nice stuff. It was in BG44K until about November when it was removed." Don't know if this is true or not, so I'm sticking with Techron.

I just found the answer to "What Is PEA: Techron is Polyetheramine (PEA), probably the best class of additive in that it can clean all of the components, including combustion chambers. Texaco's System 3 is the same formulation. The big problem is that they cost quite a bit more than other additive packages.

 

It is my understanding from this thread in BITOG that BG44K no longer contains PEA. The Nissan stealer I used to buy it from even dropped selling it.

 

Yes. I've seen that same point made in some other web locations. BG44K is no longer PEA, even though my original information on this topic lists this product as one of the best PEA products available. Bad move on their part -- would not use it.

 

Silvermax, just wanted to know how good is Seafoam as a fuel system cleaner. Does it contain PEA at all !?! I dumped a can of Seafoam last time and all I felt was the car was smoother in 4th gear

 

I've had no direct experience with Seafoam. I've read on other threads that it is PEA, but I can't confirm that fact. I also believe (but don't know for certain) that it is more expensive than Techron when it has a special sale price at your local auto store.

 

No PEA. From the Seafoam MSDS:

COMPONENT............EPC#............% BY WT.
1 PALE OIL...............4229..............40-60%
2 NAPHTHA..................20..............25-35%
3 IPA.........................125..............10-20%

I'm not sure what EPC# is. I'm more familiar with CAS registry numbers. 99.9% sure that IPA is isopropyl alcohol.

 

Isn't Seafoam mostly for marine applications, hence its name?

 

It might have started for marine applications, but they now claim automotive, trucks and marine use in 2 and 4 cycle gasoline as well as diesel engines.

 

Thanks CCS2k for the research, probably i'll stick to Techron next time ...

I think Techron sells for $5.69 in walmart and Seafoam sells for $5.29 in Autozone here.

Probably my car engine is already clean with those techron treatments that i didn't feel any difference after adding Seafoam. However, I need to do the other two methods of seafoam induction .. just waiting for the oil change time.

A while ago, I read here on the forums that GumOut Regane is one of the better products. Does anyone think so now ?? I had hard time finding it then, but now I see Autozone carries it. Not found in Walmart.
