Shell-Nitrogen Enriched Chevron-Techron for GZ250?

[Canuck]

Hey everyone,

I was reading through the posts concerning 10 % ethanol in our gas, but what has everyone heard about this Nitrogen Enriched gas from Shell for our GZ's...the good the bad and the ugly?

I've used Chevron 91-94 with Techron for awhile now, with no problems, I wonder if the GZ's engine would negatively be affected by this new gas additive.

any thoughts?

Smacks of paranoia to me. :roll:

If Canada uses the same R+M/2 method that the US does, you are just wasting your money on high octane gas. Been discussed here several times and no need to re-hash that yet again.

What, if anything leads you to believe there WOULD be any negative impact?

I wonder if anything has really changed or if they are just talking-up something they have been doing all along. I haven't paid real close attention but do they really say NEW ??

Probably millions of compounds, natural and man made, have a signigicant portion of nitrogen atoms in there somewhere.......including basic gas itself. Wonder which one they are really talking about ???

Any major chain will provide good quality gas for the GZ. Don't worry about the advertising show. Use 87 octane, that is all that is required. The GZ was designed to operate almost anywhere in the world with little or no availability of high octane gas.

[GZ250]

again i would say use JET FUEL and you will find yourself still on the road. i mean you cannot make this bike fly using higher octane levels and what the manual suggests should be ok.

occassionally i use the premium gas and carb cleaner just to clean the carb as some mechanics suggested to me and it costs me just a dollar or less. there could me many arguments on this but i just do it. i also get gas from any gas station that seems clean without any problem - mechanical, electrical or mental :).

love my GZ.

I live right across the street from a shell station. I can't say anything about the GZ, since I haven't had one since before Shell changed over to their new "Nitrogen" enriched gas, but I use it often in my scooter. If it claims to clean valves, I have to assume that it does.

At the end of the day, I still prefer the non-ethanol non-additive enriched fuel. You get better miles per gallon. That's been verified in all of my vehicles.

Also, for the record, many Chevron station are claiming that they have ethanol free gas. This is false. Chevron does not make ethanol free gasoline. Check the official website.
I have only found 1 gas station....1....where I can buy ethanol free gas and it's an independent Exxon station. There are 3 Chevron's here claiming to have ethanol free gasoline.

Well, I don't know about the GZ but on my Cavalier i put that shell gas in and it gave me a check engine light that only went away when I filled up again at a Petro Canada, but I gotta wonder....isn't air mostly nitrogen anyways?

[Water Warrior 2]

Wiz, try the Shell again as an experiment. I doubt it was the gas and might have been a temporary hiccup with the car. Or you might not have tightened the gas cap properly which will give you a check engine light. Any of the gas products, Shell, Chevron or petrocan should work well in the car. They are all top tier gas.

NO......really ?? (GASP) :shocked:

:crackup

I grew up working at the family truck stops and this is my experience:
The gasoline at your local gas stations all came from the same refinery, regardless of brand. The companies have agreements with each other to share production. The ethanol and various proprietary chemicals are added at the storage areas. You can't do this anymore, but we had contracts with 6 companies so we could get the best price and avoid supply problems. All of it came from the same refinery.

If you have problems with gas from a gas station, the problem most likely lies with the station, not the refinery. Gas station storage is where most problems with water, dirt, and other junk get into the mix.

If you see a tanker filling a gas station's storage, go somewhere else. Any crud that was at the bottom of the storage tanks gets stirred about at that time and can get pumped out.

I don't care for ethanol because I remember the days of it in the 80's when engines weren't designed to handle it. The alcohol would dissolve the rubber/plastic seals, fuel lines and fuel filters. Ethanol mix fuel also boils at a temperature about 10 degrees cooler than straight gasoline. This caused many problems with vapor lock in carbureted cars that you don't have with fuel injection. Ethanol mix fuels has a scouring effect on old, rusty gas tanks and clogged a lot of fuel system after the first fuelings. The Ethanol mixes also did not stay mixed. The Nebraska Dept. of Agriculture tested all of the Ethanol pumps in the state in the mid 80's. The alcohol percentage ranged from 2% to to 80% alcohol.

Eh, I've rambled on enough.

Or you might not have tightened the gas cap properly which will give you a check engine light.

?????????????? Is this something specific to American/Canadian vehicles? I've driven English/European vehicles, & NEVER seen a "check engine light". I've also never seen a detector on the filler cap, to tell me if it's been replaced properly. :??:

Probably not but they may call it something different on your side of the "pond".

It is there mainly to tell you when the emission control systems are not working right......and loss of the proper presssure in the gas tank is but one of the things it monitors.

I will hazard a guess and suggest it might have something to do with the charcoal cannister and the need for vacumn for proper operation. Loose cap and no vacumn.

Vacume is just another kind of pressure.......isn't it ?? :biggrin:

I think you're probably right.

A negative pressure or absence of pressure..........take your pick.

On my dashboard there's a little picture of an engine, that lights up when you switch the ignition on, then goes out when the engine's running. We call it the "engine management system", & it comes back on if the engine's not running right (although it doesn't monitor pressure in the fuel tank). It monitors things like timing,fuel, catalyst etc. Is this the same thing you're talking about?

[mrlmd1]

Yes, that's it. And I don't know about over there, but over here it does monitor fuel tank pressure, for many, many years now. That will try and prevent atmospheric leaks from gasoline fumes, prevent spills from a rollover, etc, if the gas cap is not properly attached or is missing. That's probably one of the first things you check if the light's on.

[Easy Rider]

if the gas cap is not properly attached or is missing. That's probably one of the first things you check if the light's on.

Apparently leaving the cap off doesn't trigger it right away. I drove a mile home from the gas station yesterday and it didn't come on..... :roll:

[mrlmd1]

It doesn't reset right away either. You might have to disconnect the battery for a few min. if it doesn't go off in a few days.
And if it's on it can be many other problems, vacuum/air leak. faulty sensor (unlikely). and many cars have more than one sensor which can trigger the check engine light to go on. You have to read the codes with a diagnostic meter. I'm having this problem now and the car runs absolutely fine.

[alantf]

A couple of years ago I was about 30 miles from home, when the light suddenly came on, & the car started to run really rough. A friend with a good bit of engine knowledge, who was in the car with me, suggested parking up for half an hour, but this did no good, so I carried on home at under 30 mph and the car got us there, although it was still running very rough. The following morning I got up to take it to the mechanic, & it ran perfectly (& the light was out). Never had a problem with it since, so I still don't know what caused it.

[93CutlassSupreme]

Missing gas caps cause SES warnings when the EVAP system detects atmospheric pressure in the system.


This will only become more common as the EPA toughens emissions standards and EVAP systems become more advanced. Some good has come from this (returnless fuel systems for example) but as ever the cost of new cars increases due to more and more advanced emissions controls.

[blaine]

I have had many vehicles were the engine light was on and the vehicle ran fine. I have a suzuki that the light has been on for over two years.Got tired of looking at it and covered it over.
