My auto-rx experince

[znamya]

Today, I finished my first cleaning phase and put new oil filter and oil to it for the rinsing phase. I did 2000 miles with it, my car is 92 nissan sentra XE 1.6 liter GA16DE with 101k miles. It was bought by my family in 92 and rarely used until year 2000. Actually from 97 to 2000, we drove it for at max 50 miles.And for 3 years, we didnt change the oil. Then my sister drove it for 2 years putting 20k on it without changing the oil at all, After I get the car at 86k 2 years ago, I changed the oil every 1k until 94k and now every 3k. I change my own oil and I used usually mototech brand oil which Kroger sells here, because I got the 3 cases for 5 dollars when they were trying to get rid of it.

Anyways, about auto-rx, I didnt feel any difference before and after using it, to be honest I was expecting some things to happen as people are saying. I have front main seal leak and it is leaking 0.75 quartz per 1k.Still leaking the same amount, About mileage,I didnt observe any change. I am still getting 38mpg mixed city and highway.(I drive the car never exceeding 3000rpm,thats why it is high). About the engine sound, my car is always doesnt have any noise at the idle, the only way is to look at the rpm of the engine, still the same. Actually, my aim is to stop the leak, otherwise I will change the front main seal by myself which is not fun, hope things will change. I am not saying this stuff is not working because I know that it is too early to say it. I was gonna cut open the filet to see the results but the filter that I used was Advance auto oil filter and I coudnt cut it to open.

I also told my father to use Auto-rx in his Nissan Altima, he said no, he doesnt believe these things. Hopefully, my leak will dissepear so I can put this stuff into his car too. By the way, his car is 1994 Nissan Altima with over 450k miles with original engine, original transmission but he always takes his car to Nissan dealer for maintanance and they use Pennzoil oil and OEM oil filter.

The GA16DE seems to be known for front main seal failure at around 100k miles. The same thing happend to my sister's '97 Sentra at just over 100k. The seal is physically worn, and Auto-RX will not be much help there. However, I do feel that it will certainly be of benefit for the rest of the engine. If you want some tips for doing the front main seal replacement look here: http://www.nissanforums.com/showthread.php?t=70714

It may take up 3,000 miles or more into the rinse cycle before the leak close (if not worn).

Thats how lone it took one of my cars.

I agree with the seal. Mine was replaced about 85,000 miles. It may need to be replaced. I have had good results so far on my 93 Sentra. But, this car had years of driving 2 miles to work in the middle of winter, many times a day with a job I had. Did a lot of stop and go. Also, I used Fuel Power in combination with the Auto-RX, and did two treatments of Auto-RX. It may also be your driving style. I noticed the most gain a wide open throttle. You are getting great mileage! Your Sentra seems like it is in great shape, apart from the seal. Mine was dying, literally. Failed emmisions several years ago, and many trips to the mechanic. So, that might account for my noticable improvement.

Yeah, hope I dont need to replace the front seal,actually my mechanic said, he will do it for $100, which is not bad at all. But I instead I ordered two Auto-rx for 45 bucks to see the results, I know the sticky in Nissanforums.com about replacing the main seal but I dont know, maybe I am just lazy.

About the mileage, it is manual transmission and I changed sparkplugs, fuel filter, PCV valve about 10k miles ago. I also drive my car like old lady(no offense please)I dont push the gas pedal and brake very fast if the light is red in front like some idiots in here. Actually, after I put the Auto-rx in, I went to Miami from Atlanta with 70mph at cruise control and my mileage was 40.8 mpg. And about the emission, two weeks ago I was in and my walues were 1/20 of the maximum values.Maybe that's why I didnt observe anything. But anyways, I will do two treatments and let you know the results

 

[MONKEYMAN]

Seems like a decent price for the seal replacement. Mine was over $200 at the dealership. I agree with replacing it a DIY project. It would be my luck that I would not be able to get the crankshaft pulley nut off, with the tools I have. Considering your sister did not change the oil for 20k, and knowing this engine can be hard on oil (my experience), the Auto-RX may clean deposits, even if it does not resolve the leak at your seal. My front seal and rear seal are leaking more after doing two treatments of Auto-RX, but nothing on the ground. Still have 2,000 miles of driving for conclusive results. But, my car runs like a champ, so I am not complaining.

I want to be the first to tell you that a maintence schedule like that is shameful! I would be ashamed to have anyone know I was neglecting a piece of machinery that way!!!

Rest assured you have some sludge in that engine!!! Even if Auto-Rx is able to remove the sludge I would not expect it to make a huge diffeence in performance. Your describtion above is a recipe for sludge and dry rotting seals! You may also have accelerted pitting on surface's that would affect sealing.

1) 50 miles of use over a 3 year time frame bad!
2) No oil change dureing those 3 years and 50 miles bad.
3)20,000 miles of use over a two year time frame with no oil change bad.
4) No history of maintence from 20,050 miles too 86,000 miles bad.

While I am sure their are worse cases of neglect this car had a rough start in life! Auto-Rx can clean the sludge out but it is not going to fix any accelerated wear and tear due to neglect!

I definitly agree with you word by word. Thank you. But my father was gonna trade this in for a brand new Nissan Murano in 2003. They gave $500 to this car so he bought the murano to my mom without trading this car. So the car is mine until then, I did everything to make this car run for at least 10 more years, now the car is not that bad I think, I changed oil 9 times with 1k interval and now add this oil treatment. I gave it a full tune-up also. Actually my father does not believe in oil changes that frequently, he changed his cars oil every 6 months which is 20k. Now his Altima has 450k without any problem at all. Maybe Nissan engines are strong or the Pennzoil is very nice oil, I dont know but that's fact lying in front on me. But I am changing my oil every 3k now.

I have a question to you John; do you think that with 2 Auto-rx treatments, dry rotting seal will still leak? or can it decrease the leak.

 

[MONKEYMAN]

Despite the lapse in oil changes/maintenance, this engine may do well. Seems to be able to take a beating in my experience. I was offered $500 for my Sentra when I wanted to trade it in. It was worth keeping as a second car in my case. I hope Auto-RX takes care of the seal issue. I was under my Sentra last night, and I saw even more oil on the frame from the front and rear seals leaking.

Uuu, that sucks. Monkeyman, as you know, in our cars, replacing the front main seal is not that very bad but the rear is really difficult (expensive) because I think you need to take the transmission out. What do you guys say about this theory of mine.As auto-rx is removing the junk in the engine and as engine is leaking oil, maybe that junk closes the gap in the seal that is leaking. People seeing the leak gone is experiencing this maybe.

 

[JohnBrowning]

If a seal is hard or dirty Auto-Rx will take care of it. If the seal is damaged in any way Auto-RX is not going to fix it! I would suspect that you are going to have to replace that seal. In all fainess though we have seen Auto-RX do some preety incredable things so give it time ans see what you see.

I am glad taht you are not neglecting the car now!!! That is good as a bad situation can be turned around if caught before too much damage is done. I have no idea about the oil you are useing. I would just make sure it is an SJ rated oil or better. IF not throw it out and buy a major brand name like Chevron Supreme,Havoline,Castrol,Pensoil etc........ You never truly know what you are getting with wierd obsecure regional or generic brands.

Sometimes AutoRx just never works. There are people on this forum that just won't own up to it.

All of this tune up in can stuff is the same. Let's get real here.

 

[Frank]

Auto-Rx works if you work it.How many posts are there on bitog telling you not to expect any improvement until you finished rinse phase.Poster
needs to follow the instructions for cleaning his engine and when thats done we will go on to trying to stop seal leaks.

Auto-Rx is real chemistry as such respect the applications for your engine problems and follow them. Thats why we guarantee Auto-Rx. That guarantee is a two way street we expect you to follow application and to read how it works so you not looking for results in the cleaning mode.

20k/6 month interval on Pennzoil dino?? UOA PLEASE!! 40k miles a year and two dino changes. I guess my two dino changes a year 4-5k oci is a chump change.

 

[bfort44]

As my Farher likes'to say,"If all else fail's, read the direction's!" I have a 03 Toyota Avalon that was not performing like it use to. I heard about Auro-Rx from a friend, figured what the heck, if my car will run better for $25., count me in. Went to the web site, printed out the direction's when I ordered. Put the stuff in my car, did the first run, then had the oil changed for the rinse cycle. Now my Avalon is running like the day I bought it and I am thrilled with Auto-Rx!! I ended up buying a bottle for all my grown children to use in their car's as they had bought them used and did not know how they had been kept up. They are now in all stages of the process, but those on the rinse cycle are seeing a difference in performance, but what do I know, I am just a lowly woman that is not mechanically inclined!

So, if the UOA sucks at a car at 450k, you will say that see you shouldnt have changed the oil every 20k. Right? Did something missing in your thinking? The CAR IS AT 450k, who cares whether the UOA sucks or not, who cares the car throws a rod tomorrow. you dont see the point, do you?

I dont know also how my father achieved this, if you ask me whether I will do it, my answer is NO. Again I am not saying Nissan are good, or the penzzoil rocks but getting a car with 20k oil changes are possible

Okay, I'll say it.

Auto-Rx is not a "mechanic in a can" (memories of Janitor in a Drum®). It doesn't "fix" anything. It's a cleaner. If it can't be fixed by cleaning, Auto-Rx won't do squat.

I'm sorry if it did nothing in your case/situation. It has, however, provided good value to the vast majority that have used it. Just ask on allpar.com (in the minivan section)for all the Caravan foggers that were cured or at least greatly improved with its use.

btw-if you're disatisfied and have actually tried the product, it has a money back offer. Use it if this is the case.

Well, as an owner of 3 B13 Sentra's and 2 of them with the GA16DE engine, I will say that the front main leaking is a typical problem for that engine. It is a quick, cheap and easy fix. I replaced mine on my current Sentra a few years ago, and it took about 20 minutes total, and I think the seal was around $6 from the dealer. The rear main, is another story. I replaced that, when I swapped from an automatic to manual transmission. Yes, the rear main requires removal of the transmission and oil pan.

With your oil change history, I imagine your engine is highly sludged. I have had my current Sentra since new, and have been good on maintenance and you can see what a mess the engine looks like here: http://theoildrop.server101.com/cgi/ultimatebb.cgi?ubb=get_topic;f=5;t=003064#000000

I am currently just starting my 2nd rinse phase, and will update the post with more pictures of the engine and filters this week.

Awesome, I am looking forward to that pictures and updates. Yeah, I guess I will need to change the front main seal, by the way, did you change PCV valve in your GA16De lately, my leak was 1qt/1000miles and after putting a new PCV valve, leak reduced to 0.7qt/1000mile.
