Ive got a 97 manual transmission Saturn SWII with 170K on the clock that was bought new and has had regular dino OCI every 3K+ miles. Its always run good but burned oil as just about every other Saturn out there. I consistently got 32MPG until recently it has gone down to 27 in the last year. Off hand I cant remember exactly how much oil itll use. (brain fart) But it was around a quart between OCI.
After reading about ARX I figured Id give it a try. I did a compression test before and took pictures of the valve train for comparison after the rinse phase. As seen below the numbers look bad.

So far at about 1000 miles into the cleaning phase Ive noticed an increase in performance, even the wifey noticed it in this 4 banger. J Gas mileage has improved slightly even with installing new plugs. From 27 MPG on the 1st fill up to 29 MPG on the 2nd.
The other vehicle Im using ARX on is a 92 325I auto transmission that I got about a year ago with 154K on the clock. There was no history on this vehicle and judging by the way the exterior and interior looked it wasnt very well cared for. But for $500 I wasnt passing it up. J
Im about 1000 miles into the cleaning phase the MPG has increased with every fill up 21 MPG was typical and have gotten 23 MPG on the 2nd and 25 MPG on the third fill up.
No valve train pics for this vehicle but I do have compression test numbers and like the Saturn they arent good. This vehicle burned very little oil but would leave a light smoke trail when given the gas. I have not noticed that again since ARX. Next time I have it up on stands Im pouring some ARX into the transmission.

Ill post the entire excel file on both vehicles when Im done. Im using Oreillys 5w30 dino oil for the clean phase.
No I'm not finished and I'm looking forward to even better results. :) Tonights fill up on the Saturn got me 30.5 MPG. I know its not the plugs, pcv valve, coolant sensor or O2 sensor that I recently put in and that only leaves one thing thats caused this improvement. :)
BTW here's some before pics of the Saturn valve train.
I plan on posting after photos and compression #'s and continue to monitor gas mileage. Numbers don't lie. Wouldn't both these vehicles with their high mileage need another cleaning treatment before the maintenance dose?
Headin South saw your post on "bimmerforum" neve never use Seafoam in engine oil or transmission fluid.. It is a solvent. Your suggestion to use Auto-Rx in the transmission is good however you only keep it in 1000 miles and than change fluid and drive on (no extra product needed for transmission etc) You can get application instructions of www.auto-rx.com on "index" on home page just click transmissions.

Seafoam has a "Trans tune" product thats made for transmissions and the Seafoam motor treatment is recommended by Seafoam in the crankcase. I used the Trans tune in my wifes 325 a few months back when she had a problem with her trans and since then it has not returned. While I had heard of your product I wasn't convinced and considered it just another snake oil product. It took some more research before I wanted to lay down more $$ for your product. At $20+- a bottle vs $5-6 for SF. Before my next Trans fluid change I'll be using ARX in the BMW.
While I agree its not the best idea to thin out your oil. It was my only other option before your product. I've done the MMO soak in my Saturn and it did nothing tangeable and neither did the SF. Mentally did it make an improvement? It felt like it but Idunno. Since using your product I have the seat in the pants improvements (again is it just mental?) and numbers to back it up. (Tangeable proof)
I don't remember ever telling anyone (but I could have) to pour it into the crankcase but have had better (mental) experiences and ALOT of white smoke having it sucked into the intake manifold via the brake booster line. Did actually do anything besides remove some carbon? Probably not.
I'll keep you posted as my numbers come in. So far its been a gradual improvemnent in both my vehicles. If the water ever returns to Lake Lanier I'll be using it in my boat. :fingersx:
Drove the BMW last night and it does feel better and seems to be running smoother. Should be doing another fillup today so I'll post the new MPG #'s.
My familily lives in and around Lake Lanier (Dawsonville) I coached at Murphy Candler for years. Your comment on using Auto-Rx in your boat engine is a good one . The price and procedure of cleaning a boat engine by old ways is cost prohibitive at least to me.
Not sure what was going on with the BMW but for the last 2 weeks I had a 1221 OBDI issue. (O2 sensor) Installed a new sensor and still had the same error and intermittent rough idle. Did a bottle Techron fuel system cleaner and still same issue. Then yesterday after filling up again 3rd tankful. The CEL is gone and the idle is fine. Idunno Did ARX loosen some crud up and effect the O2 sensor? Can't think of how but I also doubt I got 2 tanks of bad gas.
Not sure what happened just hope its gone. I checked and cleaned the MAF, ICV, TPS, plugs, coil packs, air filter.
Auto-Rx cleans all internal sensors not just oil lubricated rotating engine parts.Internal Engine Sensors attract dirt-contaminants etc.
Once rinse mode was done none of what you described would have been an issue.
It is not unusual for oil light -temp guage to fluctuate during clening phase all returns to normal after rinse phase is done. This includes all pressures also.
Having trouble? Can't pass your state's emissions test? We can help.
Auto-Rx® is designed to clean your engine from the inside, breaking up carbon deposits and removing varnish from all lubricated surfaces, thus improving compression and combustion and reducing exhaust emissions.

The Saturn's still getting 29 MPG. I'm guessing it'll improve if/when cyl #3 compression problem clears up. Got my fingers crossed ARX will clean it up.
The reason for the change in mileage for the cleaning phase increase from 1500 miles up to 2500 miles is to maximize the effectiveness of the cleaning phase.
The product formulation has not changed. Users with heavily sludged motors should take note to change out the oil filter at 1250 miles during this phase. The other hidden benefit is that the host oil during the cleaning phase is run for an extra 1000 miles, which provides for greater economy.
Used oil analysis was the primary consideration for extending the cleaning phase. Wear metals remained amazingly low over 2500 miles of cleaning. The host oil, with the cleaning dose of ARX, remained healthy and fully serviceable. The folks at ARX always put safely clean a priority in providing instructions. Group III oils such as Pennsoil Platinum provide great cleaning and rinse performance, for those that feel the need to run a more durable oil in the cleaning and rinse phase, when compared to a dirt cheap dino oil.
Update on the BMW. I'm at 2500 miles into the clean phase and changed the oil & filter for the rinse phase. I'm averaging 21-23 MPG an the car has been running great. You can see a few good size chunks in the photos but in between the folds of the filter material theres a lot of little specs. Here's a few pics of the filter. I'll continue the updates as I ge the info. The Saturn has about 1K more miles to go before I do an OCI for the rinse phase.
Another update on the Saturn. Filled up the tank today and its back to 32 mpg. If I get time this weekend I'll do another comp test. I'm guessing cylinder #3 has improved just as Frank said or the other cylinders comp #'s have improved even more or both..
But I'd like to confirm the reason for the increase in MPG, its been a steady 29 MPG for weeks. 1K more miles till the rinse phase.
Update on the Saturn: At mileage 172464 with just under 500 miles till the rinse phase both cylinder #3 and #4 have come up another 5-10 psi in the compression test. #3 is at 130 up 10 psi and #4 is 140 up 5 psi. #1 & 2 remain the same.
I just used ARX in the wifes old DD a 98 Pontiac MV with 170K miles. For the last year or so its been having a intermittent rough idle and has progressively gotten worse.

Over the MLK weekend I changed the oil and used ARX. Well not 100 miles into the cleaning phase and the idle was smooth.
I cleared all the codes on the way home yesterday because the idle was still smooth at stop lights and rescanned. Both codes p0300 & p0305 have not returned. The CEl did return after another 15-20 minutes of driving but I suspect from my previous uses of ARX that the p0420 will also clear after I put some more miles under the hood.

Pay no attentiom to the date on the auto-tap. My cmos battery is shot on my old dell 200.
Oh yea, I have the laptop on the front seat and plan on monitoring the engine until I can pass inspection. I've also got compression #'s from a few months ago to compare them also when I get around to doing a comp test again. Not looking forward to doing it again on this engine its a real PITA.
I'm shocked that I saw an improvement this quickly, still having a hard time believing it.
HeadnSouth, last time I was in these forums the recommended dosage was 2 fl. oz. of product per quart of sump capacity. Which dosage did you use in the Saturn?
Thanks, Squeek

Auto-Rx Chemistry in a 12 ounce bottle will pretty much be depleted when in cleaning phase at around 95 to 100,000 miles. Your first rinse liquify,s what your first bottle cleaned.
Your engines by your post must be over 100,000 miles when your done your second bottle in cleaning mode you probably will see signs of contaminants in your filter. However it is the second and final rinse where you see what came out of your engine.
Intermittent rough idle never went away although I thought it did. I would clear the codes and they would return days later.:( Today I swapped out the Bosch platinums with some OEM AC Plats and its running smoother than ever and the CEL cleared on its own. The Bosch's looked fine but apparently this engine doesn't like them. Why the heck is that?
So after 25K miles and alot of time poking around under the hood one of the things I replaced to help it run better was the cause of the headache. Glad its only a side job vehicle.
I'll post pictures of the oil filter when I get it changed in the next few weeks. In desperation I dumped another bottle of ARX in the crankcase to expedite the cleaning process (which I thought was my problem). With the dbl dose of ARX and the multitude of fuel system cleaners I've used in the process I've probably go the cleanest engine on the state.
Don't worry, no engine likes bosch plugs, especially the fancy dancy multi-prong ones.
Amazing good info you're documenting.
Thanks, I'm doing a 2 bottle application of ARX in this vehicle. With it getting very little mileage these days I'd never get it clean. Drove the vehicle to work this morning and it is definetly running smooth. The multiple cylinder misfires are now cleared on their own. No CEL
But now I have a P0420 and a P0102, I'm attributing the P0420 to the ARX and the P0102 I'll be looking into.
Changed the oil & filters on both the 98 Transport which I did a double dose of ARX in and the 92 325I which just got done with the first rinse phase and started on the 2nd application of the clean phase.
The smaller of the filters is from the Transport and the larger is from the BMW. Still not a whole lot of debris in the BMW filter while the Transport was quite filled. Sorry the photos don't show a whole lot.
No new comp. #'s yet. Maybe next time.
The DTC P0420 never went away until I changed the Cat. I quess running it for 25K miles with a misfire killed the CC. In the filter housing pic I put a magnet on the base of the filter to grab whatever in floating around. Seems to work fairly well.
Changed the oil in the BMW and Saturn today, both were over due. But I've been nursing a torn knee cartilage since last Oct. and its rearing its ugly head again. Surgery is forth coming in the next week or so.
Still haven't had the oomf (knee pain) to do another comp check on either but I do have pics of the filter elements. The BMW filter had sludge that was gooey while the Saturns filter had grit in the media.
This is the 2nd rinse after using ARX, and it clearly shows gunk is still being removed after the treatment of ARX.
Hey gang, sorry its been a long while since I've posted. Life has been hectic.
Finally got to do a comp check on the bimmer and here are the #'s @ 181900 miles. 1-130 + 30 since the rinse 2-100 - 20 3-140 + 20 4-145 +45 5- 145 +25 6-130 +30
I may get to the Saturn before I sell it along with the Transport.
The drop in No. 2 cylinder is odd; otherwise that is quite a substantial improvement in compression numbers.
I must say that my first experience with Auto-Rx (testimony number 80) was so positive it persuaded me to purchase a full case of 24 bottles. It works and works amazingly well.

Yes, it is. The folks over at bimmerforums were also impressed as I am.
Good Luck on your surgery and i hope you can post some of the photos with your text on bitog. Your a good Auto-Rx Tester and your records are exacting. Thank you for being a customer.
