Hi.

I has pured a Auto-RX to clean my engine which is 140k on it and then followed the instruction.However I couldn't feel any differeces. What should I expect from Auto-RX? How can I find out if my engine has sludge or not?
Has anyone used the stuff?

Thanks.

 

well it shuold be faster as to the fact that there is less weight( money) being carried around!
I think 99% of "addidtives" are gimicks.There is one that I have seen some results from and that is Techron .other than that...

 

auto-rx is nto a gimmick and it is not an additive. not to mention techron goes in yoru gas tank and auto-rx goes into the oil so your comparison doesnt apply.

that said, you cant really tell if your engine has sludge without opening it up. You may see some buildup underneath your oil cap. or see staining when you look in through the fill hole. If you want to see what is coming out after using Auto-rx, cut open the old filter. Using Auto-rx takes time. you wont "feel" a difference until after the rinse phase is complete. Follow the instructions carefully and all should be well. I have used it one 3 of my personal cars and had other people use it.

 

That is from Auto-rx site. As the application, I have to use one more bottle. Do you think I have to?

Thanks.

 

did you do the clean and rinse phase already? I didnt bother with a second cleaning, especially since we arent know for sludge production.

 

there was no comparison being made! I simply stated that most of that stuff is a gimmick...it is.
second, do you ever stop to think what happens to the"sludge " that breaks loose??? sure some of it gets in the filter, some of it circul;ates around until your next oil change ,and some of the bigger pieces can and do clog up the oil p/u screen which can in turn starve the engine of lubricant. been there ,got the t-shirt.
now i know that some people wont agree with that but I am not basing this on my one or two cars that I fool around with on the weekends. I am basing this on a lifetime of experience. I have litereally grown up around cars and spent most of my adult life working on japanees vehicals.
if you are worried about existing sludge,short of an overhaul, I would suggest you use a high detergent oil(such as castrol ).I dont use it because I have no conceren of sludge.its just not much of an issue with nissans.
before I get slammed I am NOT talking about stuff like lucas oil stabalizer and x-1r and that kind of stuff.they serve a purpose.I AM talking about the "pour-in fix it" stuff

 

if you are referring to castrol dino.............it doesnt clean as no dino oil does. if you are referring to syntec, only the 0w30 is a pure synthetic and even then is not meant for cleaning.

research the product before you "slam" it. it dissolves deposits. not "breaking loose" chunks.

oh, and i dont "fool around with cars on the weeekend". i break them. and i grew up around cars too. literally (the cardboard box we lived in was in the middle of a parking lot).

 

WOW! ok it "dissolves" deposites...ok...instantly too I suppose!
look ,detergent oil does clean up sludge (dino or synth) and no oil is meant for cleaning...its meant for lubricating,the cleaning is just a helpful bonus,
about the dissolving thing, it doesnt do it instantly, its a process. so there will be stuff"breaking loose " and floating around...ugh
I dont mean to be an ***, I am just offering my experince because unlike you (the cardboard box thing) I grew up in a HOUSE with a 5 bay auto repair shop that my family owend about 150 feet away from my front door.I found out that I can learn alot if I dont know it all!

 

I have used AutoRX twice. 1st time did not notice any difference. Second time was about 50KM after the first time. On the second time, I left AutoRX in for 3,000 miles (twice as long as the 1st time). The rinse phase this time was also 3,000 miles. Car is much smoother now. The steering wheel used to vibrate a little at stop while in Drive (automatic). Not anymore. I think there is a benefit, but not like day and night.

 

Auto-Rx is not a gimmick. Please read up on how it does its business before lumping it into the same group as Lucas and Marvel mystery oil...or seafoam....

 

i did notice a difference after i used it in my auto trans and the engine....it's no quick fix but it can clean a dirty engine and trans. It's probably best used with neglected cars...like mine was before i bought it. Now my dino castrol oil is still clean after 4,000 miles, i see no use to clean my engine now.

 

You are wrong!! He grew up next to a garage!!!

 

you know, you are right! I will admit I have not researched much at all on this product. I am guilty of contempt prior to investigation,however i have seen a lot of these type products come and go and some do much damage(not saying auto-rx) before they go.
with that said you mention sea foam, i have gathered that they are pretty much considered a joke correct? well I bet if I research that product I am likely to find a lot of "miracle"claims about it, largley propegated by the manufacturer themselves(or other interested parties such as vendors and the like...).is all I am saying is I have seen this over and over throughout the years.
It boils down to this, I (and the majority of technicians I know) consider these "sludge cleaners" a bit more risky than people think.anytime you are "dissolving" sludge you will have a great amount of concentrated debris circulating in the engine, this can be very damaging.and since things dont dissolve in a uniform and constant rate,then you are going to have large deposites that can and will clog up the oil pick up and starve the engine of oil. this I have seen quite a bit.its not a pretty sight I tell you.
I am not saying not to use it...its your car do as you feel best,if you value real life experince,this is mine thats all.

p.s. BTW I thik that the lucas stuff actully serves a purpose,I dont use it myself.i even like x-1r! this I have used a lot.

 

LoL -I like you...you're alright.

 

thanks. I'm just messing with ya.

 

Auto-rx is not a traditional solvent. It does its business by gradually dissolving and liquifying the sludge layer by layer, not breaking chunks off. It doesn't affect the chemistry of the oil either like solvents do..

 

thanks,like I admitted before...I havent researched.sometimes I get caught up in the "old school"LOL!!!
when I myself would be the first to point out that we are advancing everyday.
It will probably take some good hard proof for me to personally change my opinion ...because of the evidence from the old solvent stuff.
anyway I dont need it ,my oil looks like honey and its half way through the oil change cycle. something to be said for routine maintainance I guess

 

Well there ya go...lol

 

I used AutoRX a while ago and didn't notice a difference. But then again I didn't keep stats on my car's mileage or whatever. If it got cleaner I'd never know because it's not like I'm going to pull the heads off to see what it looks like. I did it because I thought my engine burnt oil (turned out it was a leak) and for peace of mind. I might do it again someday just because I have some leftover.
