Auto-rx and Nissan Maxima

[Trouthead]

I am not sure I am doing this quite right, but here is what I did.

1995 Nissan Maxima with 3.0L V-6 approx 95,000 miles. Mobil I (5w-30) for the first 60 thousand miles or so and then Amsoil 5w-30. since then. Oil filters were either Napa Golds or Frams (I didn't know any better). changed oil approx 2x per year with about 6-7 thousand per oil change, untill the last couple of years where the oil change mileage stayed the same but the interval was approx 1x per year. Air filter has been a K&N cleaned once in a while. I live on a dirt road in Wyoming.

I put the full bottle of Auto-RX in approx 1300 ago, in Amsoil 5W-30 oil that had about 4000 miles on it miles on it and will run it to 1500 miles. Changed the oil filters twice, (Supertechs, and cut them open and found nothing)

Now what do I do? There are no oil leaks, the filters are clean, and the engine apprently did not have much sludge.

Should I get the Auto-RX oil analysied? Should I run Dino oil for 500 miles? Or should I just put in a good synthetic and run it 5000 miles and then analyse?? What do I do???

What symptoms are you trying to treat? I would doubt with your regimen you would have much (any) "sludge".

You definitely want to get an analysis no matter what you decide to do. Having done the 1 year drain on my 99 VQ engine for 2 years, I wasn't very pleased with the viscosity thickening well into the 40-weight range.

I would probably change the oil (with analysis for a baseline), put 3 quarts Castrol GTX 5W/30 and 1 quart of the Auto-Rx for the recommended amount of miles (I think 500 is correct). Then change the oil again, going back to Amsoil or whichever synthetic you prefer, and running maybe a slightly shorter interval and have that analyzed, but at least 5k so you have a "normal" oil run to compare with the baseline analysis.

That way you will have a good idea on Auto-Rx's effect, and I'll have 2 more VQ analyses to integrate into the oil spreadsheet.

And feel free to visit the maxima.org website (or do a search here) for a link to the oil analysis spreadsheet where you can see results on at least 20 VQ-equipped Maximas.

This is not the ratio Frank gives.

Auto-RX does not even come in 1 quart containers, as far as I know. It comes in 12 oz. bottles. For a cleaning you use the entire 12 oz. and you have to have a clean new oil filter. The instructions for use are at the Auto-RX web site. A maintenance dose is 3 oz.

Doesn't look like the directions were followed as on Auto-RX's website, did Frank give you alternate directions for your application?

 

[Frank]

With every Auto-Rx order, an e-mail is sent to each customer with specific instructions to re-visit the website (engines: www.auto-rx.com and transmissions: www.auto-rx.net) and follow the application instructions for your specific need. I made sure you had my e-mail address and told you to contact me if you had any questions, you did not. There is no way you can tell anything about the cleanliness of your engine using Auto-Rx and your own application ideas.

Good heavens......quart = bottle. Better now?


That pushes the ratio to 4 quarts Castrol GTX and a bottle of Auto-Rx. New filter should be a given based on the oil change occurring anyway.

OK Frank, I did read your site carefully, and the only thing I did differently was this, I changed the filter again after the first 500 miles of treatment. Your site says I did not have to change the oil at the start, but only the filter. That is what I did. I also read on this site that with sythetic oil to run it longer, which I did. Was the the wrong thing to do????

The reason for this was the prospect of a 700 mile trip I needed to take with this car. If I had a lot of sludge I did not want the filter full of sludge and the bypass valve coming into play.

I am not making any insinuation that AUTO-RX did not work. It is certainly possible with my engine I had very few deposits to clean up. It is also possible that with the extra oil filter change the amount of sludge in each filter was too small to be apparent.

More so what I wanted to do with this AUTO-RX treatment was to clean any deposits I might have. I will put another 50,000 miles on this car and want to give it the best possible maintanence. If AUTO-RX helps with that it was worth it.

Trouthead - the first thing you should do is congratulate yourself!! you have been diligent over the life of your vehicle, and made good choices on the oil you've used. as a result, your engine has nothing in common with the leased vehicle engine that gets oil changes ever 20,000 miles whether it was needed or not

folks like you and I don't get sluged up engines. I'm sure there was some varnishing, but I doupt your engine was a mess internally. In that vein, it would be impossible to fill your filters full of sludge, as it wasn't in the engine to end up in the filter.

further, autorx cleans the metal and let's the oil actually lubricate. You probably did some cleaning in areas you hadn't considered, like the oil control rings and around seals. In the end the autorx has helped you just not in the way you were looking for, like a pound of sludge in the filter. Congrats to a diligent owner, and enjoy your car! Steve
