NitroFill

[cain12]

Anyone using this? This is the company that came to see us regarding selling nitrogen for customer tires. Of course like every other company now its a service program where the customer gets $150 for road hazard and up to $300 towards collision repairs IF they get the tire service done every year.

I have some beachfront property I can sell you in Minnesota right now as well!


It sounds like snake oil to me. I have been reading that Nitrogen hasnt show any significant advantages to regular air.

My personal belief is that there is a fine line you have to walk when it comes to what you are selling your customers and this feels like it is over the line.

It's not snake oil. It's fact. I personally have been using nitrogen for about 4 years now, and on every car I've owned we have seen 2~4 mpg increase. This is not just at 1st, it's a long-term increase. My wife's VW Jetta gained 4 mpg when we did the nitro-fill. My Colorado truck gained 2, and the current car, Pontiac Vibe gained about 3 mpg. Some of the other claims of Nitrogen might seem a bit out of proportion, but the MPG gain is real.

How does nitrogen affect MPG? I know nitrogen is supposed to maintain the tire pressure longer than regular air. Is it that or something else?

(If it is that, I suppose you could get the same gain by being more religious about maintaining the pressure with regular air.)

We put Nitrofill in every new vehicle before it hits the lot at our five dealerships and sell it in all service drives. My husband (service manager) has put it in all our personal vehicles, as well as our family's vehicles and swears by it.

purchased nitro machine last year n2cel paid for it in 3 months even after spiffing advisors. now all is profit each month.avg bottom line profit $3,000 per month.best thing since apple pie and great retention builder.all the hipe is true and the customer feed back is nothing but positive.don't forget these customers also own motorcycles,trailers,motor homes etc.this is a very large market.one of the best moves i ever made.

Nitrogen also helps with alot of the TPMS systems out there, especially when colder weather hits. It helps to eliminate alot of complaints about the TPMS lights because the tire pressure is more consistant.
I agree with Harold Floyd-one of the better things to come along.

Here's what GM sez about it
but we all know that they don't know anything about cars

no where do they mention gas mileage

GM's Position on the Use of Nitrogen Gas in Tires
General Motors does not oppose the use of purified nitrogen as an inflation gas for tires. We expect the theoretical benefits to be reduced in practical use due to the lack of an existing infrastructure to continuously facilitate inflating tires with nearly pure nitrogen. Even occasional inflation with compressed atmospheric air will negate many of the theoretical benefits. Given those theoretical benefits, practical limitations, and the robust design of GM original equipment TPC tires, the realized benefits to our customer of inflating their tires with purified nitrogen are expected to be minimal.

The Promise of Nitrogen: Under Controlled Conditions
Recently, nitrogen gas (for use in inflating tires) has become available to the general consumer through some retailers. The use of nitrogen gas to inflate tires is a technology used in automobile racing. The following benefits under controlled conditions are attributed to nitrogen gas and its unique properties:

A reduction in the expected loss of Tire Pressure over time.

A reduction in the variance of Tire Pressures with temperature changes due to reduction of water vapor concentration.

A reduction of long term rubber degradation due to a decrease in oxygen concentrations.


Important: These are obtainable performance improvements when relatively pure nitrogen gas is used to inflate tires under controlled conditions.


The Promise of Nitrogen: Real World Use
Nitrogen inflation can provide some benefit by reducing gas migration (pressure loss) at the molecular level through the tire structure. NHTSA (National Highway Traffic Safety Administration) has stated that the inflation pressure loss of tires can be up to 5% a month. Nitrogen molecules are larger than oxygen molecules and, therefore, are less prone to "seeping" through the tire casing. The actual obtainable benefits of nitrogen varies, based on the physical construction and the materials used in the manufacturing of the tire being inflated.

Another potential benefit of nitrogen is the reduced oxidation of tire components. Research has demonstrated that oxygen consumed in the oxidation process of the tire primarily comes from the inflation media. Therefore, it is reasonable to assume that oxidation of tire components can be reduced if the tire is inflated with pure nitrogen. However, only very small amounts of oxygen are required to begin the normal oxidation process. Even slight contamination of the tire inflation gas with compressed atmospheric air during normal inflation pressure maintenance, may negate the benefits of using nitrogen.


GM Tire Quality, Technology and Focus of Importance
Since 1972, General Motors has designed tires under the TPC (Tire Performance Criteria) specification system, which includes specific requirements that ensure robust tire performance under normal usage. General Motors works with tire suppliers to design and manufacture original equipment tires for GM vehicles. The GM TPC addresses required performance with respect to both inflation pressure retention, and endurance properties for original equipment tires. The inflation pressure retention requirements address availability of oxygen and oxidation concerns, while endurance requirements ensure the mechanical structure of the tire has sufficient strength. This combination has provided our customers with tires that maintain their structural integrity throughout their useful treadlife under normal operating conditions.

Regardless of the inflation media for tires (atmospheric air or nitrogen), inflation pressure maintenance of tires is critical for overall tire, and ultimately, vehicle performance. Maintaining the correct inflation pressure allows the tire to perform as intended by the vehicle manufacturer in many areas, including comfort, fuel economy, stopping distance, cornering, traction, treadwear, and noise. Since the load carrying capability of a tire is related to inflation pressure, proper inflation pressure maintenance is necessary for the tire to support the load imposed by the vehicle without excessive structural degradation.

Important: Regardless of the inflation media for tires (atmospheric air or nitrogen) inflation pressure maintenance of tires is critical for overall tire, and ultimately, vehicle performance.



GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

We fill all our tires with 78% pure Nitrogen (air)

Somewhere in all of this comes the effect on customer satisfaction. Thats probably one of the intangibles.

Consider the example of the owner of a $47,000 Tahoe facing the TPS light on every morning, telling him the tires need looked at. He knows the dealership has been telling him it is just the fluctuation in tire pressure due to the vehicle sitting overnight outside. Somehow this just never goes over real well!

That scenario alone was worth my looking into the Nitro system. Maybe it is just Oregon, but our temps seem to swing enough to cause these situations to arise frequently enough to warrant us trying it. So far, 8 months worth of trying seems to have alleviated those customers concerns. I am sticking with it.

I do believe the other benefits mentioned are real, tho most likely inflated in respects to the consumer. In the world of racing that stuff really matters, but for us common folk, maybe not so much.

I will say this though. You really should not have to purchase a machine. Your chemical provider, BG, MOC, Wynns etc will probably give you one. I know they all do out here. And the machine to get, in my opinion, is the Nitroen generating machine, not the one that you have to purchase the tanks from the welding supplier. My cost on this, outside of labor, is the electricity to operate the compressor that provides the air which gets purified in the machine. No electricity, no chemicals etc.

So, along with a profit center, we look at this more as a means to help our CSI numbers. It seems to work for us.
