Has anyone here used Auto-RX in their 5th gen to clean out their engine from old oil build up on the seals and sludge that may have accumulated over time?

Have you felt any difference engine performance after? Can this engine treatment do more harm than good?

Thanks

 

Personally, I don't trust any of those engine cleaners. The only one I'd even consider is Seafoam, because it's the one I consistently hear good things about. Even in our manuals it says not to use any type of fuel system cleaners...

 

I've used auto-rx on my maxima. Couldn't tell a bit of difference afterwards.

 

now why would it say not to use fuel sytem cleaner? i thought it would be manditory for most cars around 70,000

 

Good question, but I don't believe any of that stuff does any good, anyway. I remember I got a free bottle of Techron (sp?) fuel system cleaner... Did absolutely nothing to my gas mileage. Now, I would consider spending the money and actually having the injectors cleaned, though.

 

try BG44k for your injectors. I hear it's really good stuff and cleans the injectors quite well.

 

ive put a couple stp cleaners and jiffy lube did a fuel sytem cleaner they put stuff in my gas intake manifold and oil i think

 

I think the effects of these things shines brighter on higher mileage cars. If you do a Auto-RX treatment or a fuel system cleaner treatment at 50k miles, you probably won't feel much. I am currently in the rinsing phase of the auto RX treatment at 80k, and I can say the engine seems smoother than it did before. The fuel system cleaners never really did yeild any results for me, just peace of mind.

 

SEAFOAM - FTW! I have 94K on my ride and always notice a difference every time when I use this stuff. Using it every 6 mos or so.

 

I always wonder how people know that their injectors are clean. Do they actually take them out and look at them? If not, then I'm not buying it. IMHO, it's all placebo effect. I've owned many cars and probably tried every product on the market. I've never noticed any improvements, but several product have killed my engines or led to costly repairs.

For example, I have tried AutoRX only because of all the BITOG hype. When used "as recommended," the engine does run smoother, etc. However, it feels no different than if I just did regular oil changes. Guess what AutoRX forces you to do? That's right, force you to do oil changes. That's like this new product that I've just developed. It makes you more alert and productive at work, which can lead to better income, which can lead to better health care and youthful appearance, which can lead to longer life. It can also elevate moods and relieve headaches. It's made from a proprietary recipe so I can not reveal the ingredients, but it must be activated by being mixed and drunk with fresh caffeinated double espresso. If not used as recommended, all aforementioned claims are void. Only $5 per vial. Anybody want to try it?

 

they may just say that so you have to go to the dealership for approved cleaners.

i use BG44K for my fuel system and seafoam for the intake system

 

I pretty much adhere to your line of thinking. However, with the AutoRX, try taking some of your used oil when you drain it, and let it sit for a week, then take a look at it again. Probably won't notice much. Hang on to it though. Throw a bottle of AutoRX into the engine, run it for 2k miles, then drain it. Repeat the steps mentioned above about saving it for a week. Bet you'll be surprised when you look at it after a week, I know I was.

Where do you buy seafoam, is there a specific product and if so how do you apply it?

 

check the fluids and lubricants section. i have a full write-up in there

 

Sweet...Thanks

 

My engine has 106k on it and has had 3-4k oil change intervals for its entire life. Am I safe to assume my engine is clean and does not need the auto-rx treatment?

 

did nothing for my car. waste of money!!!!

 

The only things that they had to list on the Material Safety Data Sheet was "fatty acids and lanolin". Is this the "lemony" product? Don't waste your time and money!

 

How can people claim Auto-RX does nothing? Did they dismantle their engines before and after and take comparison pictures? Doubtful. It's a well established product; BITOG people trust it, that's good enough for me. If your engine doesn't have bad deposits then you're not going to notice any miracles, why would you? Now buy a car with sludge problems and do the treatment then come back and say it's all hype.

I'm in the rinse stage of my Auto-RX treatment - haven't felt any huge differences, but I wasn't expecting to. My car's been well maintained and I expect buildup was minimal.

 

I think AutoRX works. I have ran it in two vehicles.

In my altima, I didn't notice any substancial difference, besides quieter starts after the rinse, which could have been the filter?

In another car (99 LHS), after the rinse- that thing got WAY quieter. This, I am sure of.

BTW, autorx must be run over 6k miles min, consisting of a 3k mile clean and 3k mile rinse, just so I don't confuse anyone who may not know.

 

i believe this is true. my nissan mechanic gave me bg44k for fuel injection cleaning. i believe this is what nissan does for fuel injection cleaning. he said it worked real good and etc. etc. this can be had for 15 bucks on ebay. i wouldn't necessarily go by what the manual says, if you have good reason to believe otherwise (such as this).

as far as auto-rx. if bitog says that it works well, then i believe them. i'm almost positive that they took apart an engine after using auto-rx and had good results. as far as using all the products available at your local auto parts store, lot of those are considered garbage on bitog because they will harm your engine more than they help.

 

Here is a guy's experience with Auto Rx, documented in pictures, not opinion.

I have heard that if you use cleaners like this, you may have an issue passing emisions testing (if you happen to use it near emisions test date). any truth to this?

 

I just did a seafoam treatment and def. noticed a smoother idle and smoother revs after it burned off all the white smoke, twice it poured out when i started the car so i guess i had a decent amount of crap in the intake. ran it through the brake booster line btw

 

Used auto rx... and combined Terra Clean after the rinse phrase... (When the engine is around 50000km, now is 67000km) and switched to 0W-30 since that... can not tell any difference, maybe smoother...

 

Guys, Auto-RX isn't an idle smoother, it isn't a performance enhancer, and it's not a miracle in a bottle. It's an engine cleaner. IF your engine is dirty to the extent that it effects these things, then Auto-RX will restore what was lost. If you run it through a clean engine, i.e. cleaning an already clean engine, guess what...

you aren't going to feel anything.

 

When I was looking for MAxima to buy, I looked at a number of 01-03 maxima with around 50-80K miles. Intrestingly, in all cases the inside of the engine (looking thru the oil filler cap) was exceptionally shiny/clean with no varnish and discoloration visible - I was impressed.

Perhaps maxima does not have a sludge problem as long as the owners follow some form of oil change regiment. On the other hand, my Q45 engine clearly showed varnish and deposits on the engine (again when looking from the oil filler cap hole).

So if these Gen5 are around these mileage (50-70K) and the owners have taken good care, perhaps there is not much for Auto-rx to clean - hence no real improvements experienced. On the other hand, my Camry is known to have sludge problems, I am thinkng about using Auto-rx treatment on it....

 

Jeez! Again? Please don't use this stuff. If you follow the Owners Manual "Periodic Maintenance Schedules..... SCHEDULE I", pertaining to Oil Changes, use the recommended oil and change it and the filter when you are supposed to (as well as using common sense) you won't need to use this crap. Like q45Owner above has alluded to......"most of the time the engine will look nice/shiny inside". Oils all have detergent additives to keep your engine clean. DO NOT TRY TO EXTEND the time between oil changes because of the use of synthetic oils or because of some other industry hype. Adding additives to the engine oil/doing some of these "cleanout" processes is just asking for trouble.

 

if anything use the BG product made for flushing motors out.


put it in 15 min before an oil change and watch the nastiest **** come out!!!

bg products ftw

quick clean

 

Well said. May I please see your sources, studies, and qualifications for making these claims? Particularly to the Auto-RX. Then tell me why the guys at www.bobistheoilguy.com (who run independent tests all the time) and http://www.auto-rx.com/rms13/ (provided by knapp9) is a sham in regards to this product, recommended by well regarded lubricant intellects. I have read a lot about oil additives, and Auto-RX is the first one I've used (and am in the process of using) simply because of how well it has been regarded in inependent tests and by how accepted it is by the people I trust as being knowledgeable. If what you say is true, I would like to know what it is based upon so I don't make this mistake again.


However, you do bring up the point:

I agree with this whole-heartedly, you are correct here.

However, there are some of us out there, myself included, who purchase our vehicles with 50k+ miles on them already. I purchased mine at 72k miles actually, and it now has 78k on it. For those first 72k miles, I have no idea what kind of oil-change schedule the car had been on, what kind of oil was used, or how the engine was treated. I can hardly be expected to accept "well it looked shiny through the oil cap" as a good test to the condition of the engine. I have never heard overwhelmingly negative testimonials about this product, but I have heard an overwhelming number of positive things and feedback from respectable people about it.

I find myself at better peace of mind knowing I did something to clean up a potentially dirty engine for 30 bucks and 60 seconds of my time. However, if you have overwhelming evidence that Auto-RX (and not just oil additives in general) works to damage a car or is completely ineffective, please present. The community should know.

 

if you take care of your car, use the proper high quality oil, and perform proper oil changes...you want need to use a product like these.
companies with these products prey on people that dont know any better.

 

Wow....now i remember why i steer clear of the 5th gen section



How many of you guys actually knew what Auto-Rx even was? maybe 5?


No offense guys (that first line was a joke) but dont post if you dont know what your talking about....this isnt a fuel system cleaner, its an ENGINE (as in oil system) cleaner. I doubt many 5th gens are old enough, or neglected enough to feel the full benefits, although some of you auto tranny guys might wanna try it in there.


Anyways, for cars that need the help, this stuff is great

 

If you happen to buy a used car with an unknown or suspect oil change history and/or the visible engine interior (usually it's what's visible under the oil filler cap) looks less than pristine, do two or three or more "quick" oil and filter changes, maybe driving a couple of hundred miles in between each change. This is a far safer way to "clean up" a dirty engine than using any oil additive. First, no auto company that I know of recommends them...... that's no.1. They've got a bunch of "P" engineers that I'm going to listen to long before I'll listen to marketing hype from Auto-RX or anybody on this forum or anywhere else. When you add one of these additives in the oil you don't have a clue how that may affect the properties of the oil and it's ability to lubricate etc. I just picked on Auto-RX after going to their website a couple of nights ago and then checking the MSDS info and finding the only two constituants that the company had to list on the MSDS was.... "fatty acids ---lanolin". That raised a red flag with me. Anybody who wants to get info (the contituants of a product) on most of the products that come up in this forum can get it from the Material Safety Data Sheets available from many sources online. Here is one source. http://www.msdssearch.com/ManufLinksS.htm

 

the nissan and infiniti dealer i work at recommends them? so they are wrong. BG oil additive is a proven product, so is their quick clean oil additive too.

 

The dealers can recommend it all they want. They are making bucks evertime they sell you the "service". There are the slow and safe methods and then there are the quick and dirty methods. I'll stick to the safe ones with my own car. Some products, used properly, when necessary are fine and can be the lesser of two evils. If the process/procedure is in the FSM or in a TB, then I have no porblem with it. I have done some very aggressive valve and combustion decoking processes because of emissions issues, but you've got to know what you are doing.

 

Just go over to BITOG and read in the additives forum, theres enough info in there for a fast reader to last weeks...literally, and thats just for auto-rx

 

From the owner's manual:

Aftermarket fuel additives

NISSAN does not recommend the use of any
fuel additives (i.e. fuel injector cleaner, octane
booster, intake valve deposit removers, etc.)
which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvent or similar
ingredients that can be harmful to the fuel
system and engine.

Having quoted that I noticed that a Nissan Dealer did use an injector cleaner (don't recall if it was commercially sold) during some service interval done on an Altima I once had that had the same warning in its manual. So who the heck knows?

 

I'm gonna try it soon, I have an 01 SE, with 122k miles on her. Always used Mobil 1 synthetic 10w-40 in summer and 5w-30 in winter. k&n air filter, curious to check under the covers after I complete the whole cleaning cycle. I will take before and after pics when I do.

 

Auto-RX isn't one of those detergents, which you're right, are harmful to your car. It's a natural, ether based product. The treatment takes thousands of miles, because unlike other detergents, it slowly liquifies the buildup in your engine. When you change your oil, you get rid of it all.
