Cleaning phase mileage variance question.

[Lazerred1]

We are doing a RX treatment in my daughter's RX300. She will be home this weekend, but will be some miles short of the 1500 if I change it this weekend, or she will be over the 1500 if she waits till she gets back home.

When will be the best time to change it? This is the first cleaning phase.

 

[ConfederateTyrant]

No harm in going past 1500 miles, but how many miles short would it be?

 

[Frank]

Go over the 1500 miles Auto-rx has a safety margin of a total
of 1750 miles in cleaning phase. If it is more than that replace the filter and top off oil. Get oil change as soon as you can at this point.

 

[Lazerred1]

Thanks. I'll see how the miles fall.

I went 4000 miles on my last cleaning phase (3rd treatment for 200k engine. Plan on 5000 mile rinse phase with 15w40 Delo. Have already completed 2000 of those. On this last extended cleaning I have noticed that oil burning has been reduced considerably. I was adding a quart every 2000 miles before, but now it is still full after 2000 miles on the new oil. I know that this is way more miles than is recommended, but after cutting open my filters on all other phases, I just did not see enough stuff clogging up the filters on my vehicle. I did follow the recommended intervals the first time, extended them some the second time, and now this time I'm really going the distance. The truck has a large filter and bypass, so not worried about filtration capacity in this application.

Some, like yourself, bmwtechguy, can handle it. Your issues (varnish or whatever) aren't that acute and are probably in the form of hard films. These are going to dissolve into fine particles that aren't going to (typically) be seen in the filter unless some piece decides to flake off just before you change the oil and open the filter. Otherwise, it would dissolve in the filter ..just like it does in the engine. When Frank makes a recommendation, he's got to account for something that may have massive amounts of pudding like sludge. Even that may overwhelm a filter in a short time. That's probably why he's conservative in the mileage over 1500.

I'm only saying this to qualify usage outside of the recommended mileage. It may work for many.

I extended my 2nd cleaning and rinse phases b/c of lack of "crud" or specs in my first rinse phase filter. I did ~2500 mile clean (I lost a quart of oil due to an OPSU 1k into the clean, and had to top off without adding more ARX, so I felt fine extending it) and now am on a 3000 mile rinse. No problems so far at all.

 

[surfstar]

Tomorrow I'll be driving to Vegas, so I'll have a good 350 mile road trip to really "rinse" out my 2nd ARX phase, then another 350 back on Monday. I also feel comfortable extending my phases b/c I do 90%+ hwy mileage. Heck, I'm gonna hit 1500 miles within two weeks on this rinse phase.

What about after your finished rinse cycle? I am trying to tell you how to get more MPG.

I am hoping to convey the importance of the 3 ounces of Auto-Rx used as a maintenance program.

We know how important the benefits from the Auto-Rx Cleaning, I don't think we ever got the message across about the benefits of the maintenance program.

Did you know by taking the load off your engine (clean )you take the load off your converter?

(Clean engine -no drag) you increase MPG ? how many remember that Auto-Rx cleans ring packs while you drive?
keeps compression at spec-keeps combustion to the max.

Auto-Rx maintenance plan keeps your engine at peak efficency and that translate into MPG.

If you like go to www.auto-rx.com and use home page search engine and type in emissions. Read the State Tests especially the car specs that went through testing.

I guarantee Auto-Rx To Work, all I ask you is follow application (by the way 2000 miles to complete rinse)

Yes you might vary it without a hitch . What happens if filter gets full at say 2500 miles and your cruising along? your dirty oil backs up through the valve covers, besides the mess do you really want to go through this?

 

[bmwtechguy]

In the unlikely event that an oil filter actually gets completely full and will not pass any oil, your engine will have to rely on the oil filter bypass or, on some engines, the bypass in the engine itself to at least flow some unfiltered oil to pressurize the lube system. I don't understand your statement about dirty oil backing up through the valve covers. This if very unlikely unless the drainback holes in the cylinder head suddenly all stopped draining the oil back down to the crankcase. I don't think this would happen.

Yes by all means, follow Frank's instructions exactly, if possible. And by all means use a maintenance dose. I plan to do so for several benefits-always clean engine, fuel economy, and wear protection.

 

[ThirdeYe]

This is kind of taking the thread in an opposite direction, but i'm going to be leaving on a long vacation road trip where I won't be able to change my oil in a week or so but I still have 500 miles to go on my clean phase. I'm assuming by the time I leave i'll have about 200-300 miles to go. If I changed the clean phase oil at 1200-1300 instead of the recommended 1500, am I really short changing my cleaning enough to worry too hard?

 

[ConfederateTyrant]

ThirdeYe,
The directions were originally 750 miles (if I am not mistaken), but that was years ago. I would recommend waiting until after your vacation to change it. You won't do any harm either way.

I can see the concern for an engine with unknown history. I am on the cleaning phase on my car and I will extend the cleaning phase to 2k miles since I am the original owner (plus I did a treatmetn at 60K miles).

 

[surfstar]

The Vegas trip was a blast, and I think I got some great MPG given the higher speeds driven for a good part of the trip and some slow traffic in other parts - still haven't had time to check the exact data yet.

Frank, I will go ahead and change the oil at 2500 miles for this rinse phase and will be using maintenance doses for a while too and will see how things go.

Web site says 1990 Chevy S-10 in the state of NC, the link to the PDF test says 1988 Mercedes Benz in the state of MD on the report.

Drastic results in only 500 miles? The report shows years ranging from 1996 thru 2000. I thought this product was invented and patented in around 2002?

Am I missing something?

Man i really want to give this stuff a try but im only at 2500 miles with Amsoil Series 3000. I cant wait till winter time.

 

[Crashbox]

I'm glad to know there's a margin for cleaning-phase oil changeout- I'm near 1800 miles on my '95 Civic now. These long highway construction hours don't leave much time for anything else except work...

Think I'll change it out to-morrow.

I love Auto-Rx- no question whatsoever that it's great stuff.

 

[va3ux]

This also describes my situation. On ARX #3 I think I ran the clean for nearly 3K miles and the rinse was even longer. BUT, that was with the benefit of 2 previous ARX cycles under my belt with all sorts of filters cut open and no large amount of anything found in any of them.

If in doubt for ARX #1, someone could simply just change the filter for blind safety before adding some extra miles to the clean (or rinse) phase.

Nah... I think I'll change the oil out this coming week sometime instead of today; it will probably see 2000 or so miles on the cleaning phase with AMSOIL ASL in the crankcase. Too tired today to do it. I'm running the big Wix 51344 filter on the Civic so that won't hurt any either...

I'm not deliberately disobeying the Auto-Rx instructions, rather, that's life. My last ARX treatment I gave it about 21,000 miles ago I was able to follow the directions pretty much to the letter.
