Been hearing it is good stuff, just wondering if it can improve gas milage. My milage started off at about 22.2 mpg and has now slipped to around 19.9 mpg. Nissan say these things are not necessary but I have heard that Chevron Techron Complete improves performance and was just wondering if it could also improve milage.

Thanks in advance for any input.

Used plenty of it over the last 22 years or so. Never realy heard of it mentioned too much with mileage. It comes in handy as a additive to gas that does not contain that in its formula.

In my case it keeps the various gas tank sending units working right. My last4 Vettes have all had 2 tanks and its super expensive to take the car apart to get to them. Lots of work, lots of potential bad situations could occur. Its much cheaper and easier to put in a bottle ever 4-5 or so fill ups. No gas in my area has that product in it, so I get it when its on sale as most auto supply place stock it.

Many years back I had a bad gas tank problem in my 98 Vette and I tripled the amount of Techron used, took a couple weeks but all worked right after. Used it since!
 
I think Techron is a detergent I believe. If your car is high mileage and may have carbon buildup internally it might help clean some of it up slowly. It may take many tankfuls to yield any result.

The biggest thing I find that makes my mileage go down is the amount of pressure on my right foot. The next is tire pressure followed by how much stuff is loaded inside.
 
It will help keep the fuel system clean,
but I doubt it will increase mileage to any noticeable degree.
I put it in my cars once a year, since they are not driven that much.
As a side note GM private labels the same stuff, for even more money.
 
I buy Techron @Costco, the price is very good. I’ve been putting it in every car since my friend, a BMW mechanic, told me about it many years ago.
I throw in a bottle either at every oil change or 5,000 miles.
 
My retirement Car, a BMW 530I, started having issues with the fuel gauge sticking, reading low after filling up... I did some research and found that 54 different brands are rated “Top Tier” fuel and have a required additive package.... Techron is the additive package found in Chevron fuel....Shell, Mobil, etc, any as long as it’s on the list....The problem is the amount of ethanol in th fuel...Supposed to be only 10 percent, and 90 percent gas...often, a lot higher ethanol content which causes a lot of issues, including reduced fuel mileage.
 
I had a Honda Civic from 1995 to 2013 which was the best car I ever had. But it would slowly develop a spark knock over time due to carbon build-up and the resulting pre-ignition. I would add Techron and the knock would cease. Every year or so I would need to repeat the treatment.

I never knew of any claim that it would improve mileage, however; and I never noticed any change in the Civic's mileage before or after using it.

Best wishes in finding a solution,
Andy

If your baseline condition includes carbon build up , or clogged injectors , such a product can help restore your engine to what it should have already been .

But more likely what you're seeing is the transition from Summer Blend to Winter Blend gasoline .
 
Speaking of fancy additives, you might also find that your mileage will vary depending on the season as the blends used in colder climates vary from summer to winter. I also have heard that the ethanol used in gasoline can attract moisture from condensation in fuel tanks depending on the outside temperature.

I'll refrain from poking fun at the mileage your Nissan is getting regardless... :D

Well Being highly hygroscopic, Ethanol is a water sucker. I only use it in my DD that uses a lot of gas and therefore does not stay too long in my vechicles. I totally refuse to use that junk gas in my Vette, boat or 2 stroke tools and toys. Ethanol will also give you worst mileage in most cases and reduced power.:mad:
 
I am of the "buy it where it's cheapest" school of thought. Chevron is usually NOT the cheapest so I do not buy that brand unless I'm on fumes and the nearest station not Chevron is outside remaining operation perimeters. This may not work for all, but it has worked with Blue so far, she is getting ready to turn 440,000 miles and 22 years old soon. Putting Chevron with Techron in old Blue at this stage is kinda like buying my wife a thong. Wasted money at this point :rolleyes:
I will say this: I get an instant 10% increase in mileage with Blue when I use non ethanol gas-again much like like my wife-she prefers steak to ground (already chewed) meat

Back when gas varied a lot between the oil/gas companies, fuel additives were more important (especially for cheap "no name" gas) due to the existence of detergent and non-detergent gas.

But today, that has all changed due to EPA standards for gasoline formulation that specifies all grades of gas contain a detergent.

In my opinion the type of additive that one oil company uses versus another has become all so much marketing hype to illustrate that "our gas is better than the other guys".

Today, if the gas you buy has a "top tier" rating (wikipedia article with brand name list: Top Tier Detergent Gasoline - Wikipedia), throwing in an additional detergent additive is unnecessary.

When gas mileage drops, start with the basics first and check for the common things that can affect mileage, such as low tire pressure or a clogged air filter.

As already mentioned, a change in seasonal gas formulation can do it too.

Also recommended by the Tech Nerd at Corvette Magazine to keep the sending units working. No mention of mileage improvements. Tried it in my Sequoia, which went from 18 to 16 MPG. Didn't help.
 
When cars here in Texas still had to pass tail pipe emissions tests Techron would definitely improve test results. The only gas additive I saw that could have a definite improvement. Scan tools can show you if you need cleaning .

I’ve used it for years but haven’t been able to find it at our Costco in the past year. I was hoping they’d start carrying Techron-D too (for Diesels) but so far haven’t seen any.
 
Too many variables here to judge whether Techron would fix the OP's mileage or not. Some questions:

Exact model of Nissan? Maybe that model has a habit of furring up the injectors. Google?

Good service history?

Has the OP's gas station changed management/brands?

Has he started going to a different gas station?

Has his wife been driving it more lately? (Definitely creates a mileage problem at my buddy's house)

Are the tire pressures what they should be?
