I purchased a bottle of Gunk Flush from Mal-Mart and wasn’t really happy with the way it cleaned, or for that matter the way the oil drained out. It was still a little bit like Honey. I remember years ago using an Amsoil product that I can’t get in Alaska anymore. I remember after using it my oil seemed to stay clean for a very long time and when first drained after the flush the oil drained out like water.

Would anyone happen to know of the best flush product on the market today and how to obtain it?

Regards,

Stay away from the engine flush treatments. There is a possibility of some of the oil galleries being plugged up by any sludge that may be broken up. If you want to clean out the engine, run a diesel grade oil in there. It has better additive packages and will slowly clean out the gunk in the motor.

 

IMO, AutoRX is the best flush product on the market. Do a google search on it.

 

I just received my bottle of Auto-Rx today and I am trying it in my 1983 Ford F-150 (83K actual miles). I ususally don't buy into additives but the recommendations for Auto-Rx on www.bobistheoilguy.com are very positive. Auto-Rx's web site is www.auto-rx.com. It should be some time before I finish my engine treatment with Auto-Rx so I won't be able to post any results for a while.

 

Did you warm up the oil before draining it? What weight did you have in there?

 

BITOG.com is heavily supported by Auto-RX.

 

The support of BITOG by Auto-Rx would be an issue if everyone using it were owners of BITOG. These are individual members who seem to take their oils and their engines seriously. Many of them compression test their engines (before and after) as well as remove valve covers and post pictures (before and after). In addtion, many do UOA's on their engines before and after. Anybody that **** about oil, I'll take their word if they say it works. I have also seen individual web sites posting results by satisfied users of Auto-Rx. I figure for $25 bucks, if it does what it says it will do (many posts on BITOG attest that it does), I've got a lot to gain and little to loose. If something works, I tell all my friends. If something is a rip off, I tell all my friends. As soon as I complete the Auto-Rx cleaning, I'll post the unbiased results from a user not affiliated with Auto-Rx or BITOG. Thanks! Larry.

 

How can you be so sure of their independence from Auto-RX.

There are many, many posts, in many forums, talking about how good Amsoil is. As it turns out, at least some of these posts were by Amsoil distributors.

Look, it the stuff works for you great. Buy a tank of it. But through the years, every engine manufacturer has tested (some quite extensively, Briggs & Stratton and GM, for example) virtually every oil additive/cleaner/secret elixcer available and none of them, none of them, have been found to be of any benefit.

I just think that the chances of Auto-Rx finding exactly the right secret formula to be the miracle cure that it claims to be are pretty slim.

 

Frankly, I am not all that impressed with AutoRx. I ran it in my F150 which was sludged (oil pickup screen half plugged at 70,000 miles). I really don't see it any cleaner through the oil filler hole on the valve cover. My blotters are no better now than before. During AutoRx I got some nasty looking blotters and black gooey blobs in the filter that I really don't know if were from cleaning or the AutoRx balling up. Who knows. And I ran two cleaning and rinse cycles. I won't run it on my other vehicles as the synthetic I am running seems to be doing a cleaning job of its own. I will say my PS leaked at the shaft into the rack and 1.5 oz Auto Rx put in and within a few hundred miles the leak stopped. Also the fluid turned dirty. So maybe it works, but in my F150 it didn't seem to.

 

Well,

I'm not sure if any of the posters on BITOG are affilliated with Auto-Rx or not. I inquired abouit distributorships in the U.S. and was told that there are none. The only two things I know for sure are that I am not affiliated with Auto-Rx and the product has a money back guarantee. If it does what it claims, it will be worth the $25. If not, I'll be requesting my money back. It I get stiffed, I'll go straight t Visa for a refund. I know that there are a lot of products out there that do not do what they claim. That's why I was relying on the input of those (hopefully non-affiliated) users of Auto-Rx who have tried it. The word of any satisfied user is much better than any advertisers hype. Due to the overwhelming number of junk products out there, I can understand the skeptics (I are one!!). Of course with satisified users of Auto-Rx, there are those who probably get a psycholgical boost from the product more than an engine boost. As for me, the product is already in the engine. In 1500 miles, I will either be a supporter or a very vocal detractor of Auto-Rx. I don't like being parted from my money or seeing other people parted from theirs either.

 

Once again, if you see a benefit, that's great.

As far as the "Money Back Guarantee", that's really just another marketing gimmick. It's all statistics.

By offering a money back guarantee, a certain % of people will try something that they otherwise would not. Of those X%, Y% will actually like the product (for whatever reason) and continue using it. Of the Z% who don't like the product, only W% will actually ask for their money back.

Either way, you get some additional sales immediately, and a certain amount of continued sales. It's all marketing. The secret is to get people to try the product. You can't sell it if people won't try it.

Think about it, products like "Diet-Rx" offer money back guarantees. "Your money back if you don't lose weight".

Do you really think that you can drink all the beer and eat all the pizza that you want and still lose weight?

Sorry, don't mean to be critical. Everything new has its skeptics. If people didn't try new things, there would be no progress.

BTW- I looked at the Auto-Rx patent. The formulation looks suspiciously like biodiesel. Kerosene-like oil additives have been around a long, long time. Maybe the esters in biodiesel work better than kerosene at cleaning. I don't know.

yes i saw that too. kinda scary.

 

No offense taken on any of your points. They are all valid. I'm glad to see that you checked the patents (I wouldn't have known where to start with that one). Any good research is better than "this is good, that is bad" repeated by those who have bought into advertiser's hype. Skepticism is a good thing, one I hope to always have an ample supply of. Thanks for ALL of the feedback!

Sounds like sheep oil...

 

I for one will attest in favor of Auto-Rx.

It takes alot for me to give any thing additive related a thumbs up. I too was a skeptic untill I actually tried it.

A very long time ago I posted some pics of a Auto-rx ing that I had done on a F150 Supercrew 5.4L. This was done right after I bought it used. According to the owner this motor never saw any neglect. The motor had 100k mi at the time of the auto-rxing.

I'll try to find those pics.

Found some of them wish I had one of the oil filter.

This pail was spotless before draining the oil, and the oil sat in this bucket for no more than 10 min before being dumped into a waste barrel. This oil was from the cleaning phase, 1500 miles only on it, 5w20 Castrol, and nothing else.




My .02.

Sure wish I had kept those photos on the before and after oil filters.
