I like to use water. It doesn’t work very well but man, the price is right.

 

I appreciate the suggestion. Luckily I know not to use that, but be careful as others may not and your suggestion may ruin another’s pride and joy.

 

I've used HEET red bottle for yrs....17 yrs straight in my 05 F150 and never had an issue.
Been using it in my 19 CC SV and actually helped with rough idle....

 

You might Google "Top Tier" fuel. Allegedly contains specific helpful additives. Some think it's a scam, you can make your own judgement.

 

In all seriousness I’m on board with the Top Tier fuel. Also I like Chevron Techron for an additive. I don’t use it, but I would if someone gave it to me.

 

+1 on Chevron Techron, I've used it for over 35 yrs and still do in all three of my vehicles. I also use BP gas when its convenient as it is Tier I and has extra cleaning additives. I use BoostThane in my weekend toy to make "racing gas" out of premium as the first gen DOHC Chevrolet 3.4Ls love extra octane and the power difference is noticeable. The ECM is chipped so it does use the advantage of extra timing. We're talking 1992 so it really is "chipped" as it uses an EEPROM to store all the fuel and ignition tables.

 

I started using HotShot Secret Gasoline Extreme in my vehicles. Gives me peace of mind.

 

95% of all fuel additive products, and top tier gas all utilize P.E.A. as the main ingredient. PEA was invented in the 1980's by Chevron and was trademarked as Techron. The other minor ingredients that you'll see are alcohol and naphtha.

 

I use a can of Coke (not diet or Zero)
Cleans everything

 

It's a mass produced, low compression motor designed for 87 gas....
I never used anything in any car I have owned & I never noticed any negatives.
Waste of your $ IMHO.
Stay away from cheap low quality side of the road backyard gas.

This used to be a thing, but even Bubba's Bait and Gas in the middle of nowhere has quality fuel. To many regulations have even made the cheap gas decent.

 

As one that won't argue using top tier fuel is the best idea to begin with, it's still not a bad idea to use a fuel additive to help keep the fuel system clean every once in a while.

For me I personally like to use Berryman's B-12 Chemtool every 5,000 miles(aka every oil change service). Does it make the vehicle gain a lot of power or somehow fix a problem? Not necessarily, but it does help keep the fuel system clean.

That said because you do have a direct injected engine on your truck it is highly recommended to do an induction service every 30,000 to 40,000 mi. This will help keep the intake valves clean over time. If you don't have the tools to performs head service you are more than welcome to talk to a local dealership or shop that you trust to get an idea of what that service involves.

An oil catch can does the job of keeping oil vapor out of the intake, making the 'induction service' irrelevant / unnecessary IMO.

 

I fill up at Costco and they seem to have high rated fuel.

 

This is all I do. I'm approaching 200k miles with no fuel issues. My only issue with out of the way / not named gas stations is the possible age of the fuel in the tanks. This is why I like Costco, the volume of fuel they sell daily means that fuel in the tanks is Fresh where the fuel in a lower volume station may have been in the tanks for week(s).

 

The only thing I have used was injector cleaner. Never religiously. Just a feel good bottle once in a while. Our newest car has direct injection. I did a deep dive into fuel injector cleaner, and ends up with a big bottle of Lucas brand stuff. Put it in all of the cars. I don't think I am seeing any performance gains. Will probably do so again in a year or 2.

 

I used to add Seafoam to my fuel every oil change in my old Silverado due to a sometimes sticky injector.

My C6 Vette I used Chevron Techron every few months to help lubricate the fuel pumps (seems like it was a common thing to do)

I haven't added anything to my '24 but was thinking of adding the Techron the other day.

 

I add a bottle of injector cleaner at same time as my every 8,000 kms oil change.
Is it helping any? Who knows! Makes me feel good though.

 

I use Marvel mystery oil or lucas sometimes. Fuel around here isn't the greatest.

 

I shoot for top tier fuel and will probably run a bottle of seafoam/marvel/injector cleaner every other oil change. It may or may not be necessary, but if it can't hurt (IMHO).

 

On occasion I use Amsoil fuel additive. Works well enough.

 

Owners really don't know what to believe. Can't? Always follow the manual. ??

 

TC-W3 - Yes, marine 2-stroke oil. I'll let you do your own research to determine amounts and whether you want to try it but I have ran it for 40,000+ miles now with nothing but great results. Way quieter start ups, smoother idle, slightly better mpg, and maybe even a bit more power.

 

There is undoubtedly a wide range of 2-stroke oils, so...
Really curious just how compatible combusted/oxidized 2-stroke oils are in the primary cats? Some minerals, such as zinc, will murder the catalytic material.

 

Seafoam twice a year added to fuel.

 

i used 2stroke oil in my dodge diesel for 15 years when i couldnt find biodiesel. as stated it really quiets a down the noise, diesels also have cats, and mine were functioning fine at 15 years old.

 

Seafoam every once in a while.

 

Anyone use fuel additives?

I only run anti-freeze in the gas for the fuel lines in the winter, it will remove the water. I was also using Sta-Bil because I don't drive that much, but have stopped using it. Be very leery of any additives especially octane boost. I never let my tank go below half in the winter time.

From the owners manual:

Aftermarket fuel additives
NISSAN does not recommend the use of
any aftermarket fuel additives (for ex-
ample, fuel injector cleaner, octane
booster, intake valve deposit removers,
etc.) which are sold commercially. Many of
these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.

 

per the MSDS, HEET is greater than 75% isopropyl alcohol, 17% ethylbenzene,

 

I used to put gas line antifreeze in the winter months back when I drove carburated vehicles from the 80's. When I got my first car at 16 years of age I would geek out over all of those additives and '81 Corolla of mine had seen almost every additive available at the time 🤣 Since then, I stopped with all that.... Just gas in the tank, oil in the crankcase, coolant/water in the rad... The normal stuff. And I've had vehicles hit over half a million km's just by doing regular maintenance with no additives of any sort. I'll continue down this path and pass on any additives, but this is just my own humble opinion.

 

more likely in the range of 400:1

 

So, 6.72 oz/21 gal tank. A quart of 2-stroke oil will nearly treat 6 full tanks of Frontier fuel at this rate. Bought in quantity, this then isn't terribly expensive compared to using traditional fuel additives.
All this talk now has me curious how combusting anything viscous/oily can be called ashless... IOW, burn it up and poof it's all gone w/ zero residue? Ideally a combustable fuel will yield CO2 & H2O. My 2-stroke weedwhacker & blower sure do leave a stink in the air.
