Neutra 131 questions

TallPaul · Dec 22, 2004

Neutra 131 is highly odoriferous, though pleasant smelling. But rather than smell it on the drive to the filling station, can the 131 be put in after returning from the filling station or would it affect the filler neck hose (vs the hose being washed off by the fuel if installed at the pumps)?

Alternately, if I have 3 or 4 gallons gas left in the tank, can I put say 16 oz Neutra 131 in and drive to the filling station or will that represent an overdose that may make it sputter and pop?

The dosage for 131 is much higher than 131c and for other fuel system cleaner/treatment products. Am I correct that a dosage of 1 ounce per gallon is appropriate for continuous application?

Finally, due to the strong odor, I am NOT keeping this stuff in the house. How does it fare in the garage with zero F temps and 90 F summer temps? And what is the shelf life?

Why don't you do what I did with my supply of 131? I have got it inside a box, and inside that box it is inside some plastic. So you cannot smell it at all. When you open the box you sure can though!

It's tucked in my oil shrine, which is in my laundry room.

Both products are excellent fuel additives ! I don't like them used in the crankcase and BOB and I went around and around on that low flash solvent issue!

BOB was sharp on knowing his products and asked me to test these products. I did some testing but was never funded enough to publish that look we took.

The 131 and 131C are basically the same effect fuel side using slightly different chemistries, Soy esters being the difference. I love supporting the American Farmer so I prefer the 131C.

I think for CC cleaning they are excellent but do not need to be used every tank or frequently.

In limited testing of these products we saw no MPG increase but cleanliness of the CC was exceptional. Lubricity for the fuel delivery components was very good too.

The Molabrew of 131 and FP is a very nice package used periodically.

Bob Winters was very knowledgeable about these fluids and I wish he would chime in here.

As far as shelf life I have samples here from 4+ years ago that are still "fresh" for use.

I'm glad to hear the shelf life is at least 4 years. I've got probably 4 or 5 bottles left, and I save them to use in my wife's car. I'll throw a full 12oz bottle into a full tank about once every 6 months with her car. I save the FP for my own car.

One thing I find puzzling is the difference in recommended dosages between 131 and 131c (from Schaeffers site):

131: Treatment Level

For gasoline: Add 2 to 3 quarts of Neutra to every 100 gallons.
(that's about 8 oz per 10 gallons)

131c: Treatment Ratio:

Keep Clean Performance - One gallon of Gasoline Fuel Additive to 1500 Gallons of Gasoline.
(that's just under 1 oz per 10 gallons)

Clean Up Performance - One gallon of Gasoline Fuel Additive to 300 Gallons of Gasoline.
(that's about 4 oz per 10 gallons)

1-Tank Clean-Up - One gallon of Gasoline Fuel Additive to 150 Gallons of Gasoline.
(that's about 8.5 oz per 10 gallons)

So I am not sure why the 131 does not give the same detailed breakdown as the 131c, but given what Terry says I suspect it is the same.

So probably, with either product, the clean up amount every 3000 miles or so and then 1 oz per 10 gallons the rest of the time. And then when a vehicle is in storage for several months, probably the heavy dose.

Make sense?

Shelf life 2 years. Temp ranges will not effect it. Overdose will not be harmful. You can top off after filling up with same results.

Spector · Dec 23, 2004

Based upon my own experiences I know that the temp ranges have no impact however, I did not know it had a 2 year shelf life. What happens after that, I may have a bottle or two approacing that age?

salesrep · Dec 23, 2004

Nothing negative. You just may not get the complete benefits.

TallPaul · Dec 23, 2004

Salesrep, Based on your experience/knowledge, can you give us a basic rundown of the advantages Neutra 131 vs 131c.

I know there are sheets on the Schaeffer's site, but it is kind of hard to compare. What is it in a nutshell, including dosage levels for comparable effect/performance? And, does the 131c have less prominent odor?

The only really significant difference I gathered from some cursory searches here was that the 131c boosts octane and fuel economy, but in spite of a lower dosage level is more costly to run because of higher price, and that the 131 acts as a lead replacement. Both are top cylinder lubes.

131c soyultra has a gasoline detergency pkg that neutra does not. This pkg provides clean up and keep clean to get the most out of fuel. The soy oil adds lubricity up to 45% to the system and injectors that today's gasoline does not provide for wear. Fuel economy of 5% is from the detergency pkg and friction modifiers. Even with new vehicles.

Analysis of motor oil ran the last 1500 miles of the interval with 131 in the crankcase with two back to bacl 12 ounce bottles ran in the tank .

I like the product description of the 131C and want to try some

I agree. Now we need a smaller bottle size than 5 gal pail...

From the product descriptions it appears the 131 has a few features not listed for the 131c, including dispersing gums, anti-rust, anti-corrosion, stabilizer for storage, and handling moisture. So given that, I am still leaning to 131.

Or maybe we should try a 131 & 131c brew. Power, lubricity, cleaning, etc.!!

Clean you PM box out a little would ya ? It's full and the money for the 131C is just burning a hole in my pocket

Thanks Bike. Glich in the system. We're trying.

I like Neutra 131. I use it primarily as a fuel additive but have used it successfully (and sparingly) as a flush. Usually 1-2 ounces in a full 4-5 quart sump. Run it around for about a week (200-300 miles) before draining.

But I don’t do this when I want to send away a used oil analysis.

I did this for Dad’s 4.6L Ford V8 and the subsequent fill of oil stayed cleaner much longer.

Also, I feel that most engines could benefit from additional fuel lubricity. This became even more apparent to me when I was told my Honda Civic’s head was showing signs of valve recession at 100,000 miles.

I like Schaeffer products in general and have yet to be disappointed by one. So, While I am using Fuel Power and still occasionally use Red Line SI-1 (until my current stock is gone), I still want to maintain a stock of Neutra for occasional “keep-clean” use in my daily driver as well as blasting the occasional piece of lawn & garden equipment which develops ‘skipping’ and other “runnability” issues.

But I am still torn between buying 6 – 1 gallon containers of 131 and a 40lb (~5 gallon) pail of 131c the next time I order Schaeffer products (probably this spring or summer).

Odd that 131 would claim to be a lead replacement and 131c would not ... yet 131c claims greater lubricity. What am I missing?

Still confused.
