Neutra 131 Engine Cleaning
- Thread starter Dan4510

I believe the instructions are on the container. 1 Oz per quart of oil ( I used a whole bottle ) and run for 500 miles. No rinse cycle
I just picked up 4 gallons of Neutra 131 (I'm going to sell some to the local shop). Does anybody have good instructions for the amount to use per quart of oil, how long to run it, rinse, etc...? Should I use the same procedure as Auto Rx? I'm going to finish this off and then use the Schaeffer blend that I picked up. Thanks for your help.
I tried Neutra in the crankcase of my 79 BWM 320I.Works great!
Noticiably less junk under the valve cover,less oil consumption and better running overall.
I put in around 6 ounces with a fresh oil change of Delo 400 and new filter and ran it around 1k miles.When drained the oil did have a lot of crap in it floating around.Not big chunks.
I just put in 5oz in a sludged Hyundai Elantra motor(with castrol GTX 10W30).It's cleaning it.
Overall I am very happy with my Neutra purchase and plan to buy more.Good stuff!
Thanks Bob!Get well soon!

I just put 10 ounces in the oil of my crap car and put about 5 in my gas. If it works well I'll put some in my Saab. I got four gallons of the stuff (for the same price as two twelve ounce bottles of the Auto Rx) so I'm glad to see some good threads on it.
Auto-Rx is non solvent and safe for engine-passengers and enviorment. Solvent technology
for gas good.Good rule of thumb is to read MSDS on any product you put into your engine oil.eg.
Does it change viscosity of oil? and if price is your main consideration, cost it out in benefits,
different applications (you don't put solvents in transmission fluid, why is that ? )also power steering unit or differentials should be solvent free. If your engine is frozen and won't turn over
than use solvent technology as directed.

Perhaps you should reread this post from one of the best additive chemist we know.Auto-Rx is a natural ester. They use synthetic esters in prepackaged oil and they don't clean much.

Molakule,
Are you saying that the CA and n-butyl are pre reated as received in product 131. If so why is either listed on the MSDS. Or are you saying that under heat and pressure of the motor, acting as the catalyst, an ester is formed?
In either event I question the volatility of the butanol in the crancase. Also question any lubrication properties. What is the other 90% of content of 131? My guess is that a good majority of the butanol gets vented out of the crankcase after a couple hours of running the motor. Sounds like an excellent fuel system cleaner though.
I had used n-butanol in printing plate preparation for many years. In a 140 degree dryer it gone up the stack in 30 minutes.

I think that you will find that Neutra 131 is safe and effective. Countless people have used it in their vehicles with no problems. I used it in a car that had a terrible case of sludge and varnish build-up and I was able to remove about 95% of the visible crud in my engine. I am currently using Auto-Rx in an attempt to remove the remaining crud left in my motor. What little build-up that is left in my motor is in an area that has very little oil flow so I am not sure that Auto-Rx will help much but I am sure that it certainly can't hurt anything.
A few people have even report that Neutra 131 was able to stop minor oil leaks.
Auto-Rx may well be a better product for a severely sludged motor but that doesn't mean that nothing else works. Neutra 131 is cheap and also works as a fuel system cleaner.
I think Neutra 131 and Auto-Rx are both great. There is room in the world both products.

I used Neutra in my oil,did analysis,no prob.I've used Rx,no prob.I'm currently using Lube Control,no problems.
Rx is the best, carrera79 just said that.
This started as a Neutra#131 thread.Please respect the mans decision to use it.

Frank,
More than a few people have stated on here that Neutra is an ester, not a solvent. Please enlighten me. I have read multiple posts, including this one
http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=5;t=000014;p=1
Where Bob states that Neutra is an ester that does not cause issues with the host oil and does not clean too quickly. I feel after reading all of the information on here that I am making a safe decision. I will definitely post my feelings on this.
P.S. From what I have read I feel that Auto-Rx is probably a better product, but I also feel that Neutra is very safe.

Frank, why is it that one doesn't put solvents in the transmission fluid? Since you mention this please provide more explaination as I was told it was ok to use and would enjoy hearing why not.
I put the Neutra 131 in my transmission fluid almost 1 year ago. I can still smell the Neutra easily in the fluid today so I don't think it evaporates out like someone mentioned. No problems with it in the Toyota's transmission that I can tell.

Auto-RX contains natural esters while Neutra is a synthetic ester in a light oil.
Neutra 131 in my Saturn car worked well. The engine only needed light cleaning and doesn't burn oil. So for mild cleaning, it works fine.
However, in my old Toyota Sludgey Sienna, it didn't fare as well. The more industrial-strength ARx is needed in this motor.
To me, it seems that Neutra 131 fares well in light-duty situations, and ARx works in all situations. But $3 a bottle, 131 is a steal for light-duty applications.
