Re: Shell's nitrogen enriched gas vs Chevron Techron??

I'm sticking with my Texaco gas. It gives me the best mileage. Not because of what's in it, but what's NOT in it - ethanol! That gives me 4-5% better mileage, depending on how you calculate from the data.

Any additive Shell puts in would have to overcome that, plus another 2% for their higher prices. I'm highly skeptical it'll achieve that level of improvement.

Is there a thread that lists the non-ethanol stations by state?

I am trying to find a non-ethanol station in the Detroit Metro area.

Unfortunately, almost every station I have gone to does not sticker the pump. The few that do, specify 10% ethanol. When I go into the station and ask, I have learned that I have to ask them to show me the paperwork because the people running the station do not know. Unfortunately, every verbal claim of no-ethanol has not been supported by their paperwork

Re: Shell's nitrogen enriched gas vs Chevron Techron??

All I know is, Nissan dealer said I needed a $300 cleaning of intake system for sticky accelerator coming off idle. Started putting Shell premium with nitrogen in my 2000 Frontier 4x4, 6 cylinder. (It will run on 89 E-10 gets better mileage with 91 premium and comes close in cost/mpg. Owner's manual recommends premium.) Sticky accelerator off idle went away. I will continue to run a tank of Shell premium with nitrogen when prices allow. However, am concerned because not all Shell stations in Nebraska advertise the nitrogen-enriched fuel. Wonder if it's going away?

That can't be true, for by law all grades of gasoline must have the same amount of detergent in them.

From my searching on the web, it seems that that stuff is the best around. My automotive teacher (who has been working in the industry for over 40 years) spoke highly of the stuff. It's not too expensive, about $20 a can and it lasts a long time. Supposed to use it about every 30,000 miles, really powerful cleaner.

If your car needs premium, mix a bit of E85 with regular gasoline.. you will get a big octane boost at low cost.. start at 10%

Re: Shell's nitrogen enriched gas vs Chevron Techron??

I suspect some of the struggling gas stations are not changing the additive cartridges inside the pumps in a prompt fashion. At least in S Florida, all the gasoline brands come out of the same pipe at Port Canaveral.. I only use Chevron brand, at corporate owned stations.

Re: Shell's nitrogen enriched gas vs Chevron Techron??

Best way to use the stuff is the hot soak method (at least with FI engines), its best not to use it before a long trip but during everyday driving.. the fuel remaining in the hot injector will soak the residue and soften it while the engine rests and cools down.

Question Re: Shell's nitrogen enriched gas vs Chevron Techron??

Recently someone (not here) said a couple gallons of additives were added to each truck tanker (they made no mention of how it gets blended) first iv'e heard of additive cartridges (not that means much) do they swap out the additive cartridges at the same time the fuel filter (in the pump) is changed ?
