Fuel treatment

[aceduce1604]

What is the best to use with the 5.0 ?

 

[Lord Humunculous]

One bottle of Redline SI-1 every 5000 miles. I also use a number of LiquiMoly products, but at the very minimum, SI-1 is your go to, reliable, actually-works, engine treatment.

They make oil too...



If you meant a true FUEL treatment cause you are worried about corn gas and water, and it's actually THAT bad, literally making your engine do naughty things, then Stabil360 or Heet is an option.

Thank you

I would use Chevron Fuel Injector Cleaner with Techron. The Hyundai version sold in the dealer parts department is made by Chevron for Hyundai. If you have a Costco membership, they typically have good deals on this, or any discount store like Walmart will have it.

I have been using Chevron Techron for years in all my vehicles.

They're mostly a waste of money. Use "Top Tier" gasolines at least most of the time, regular is fine, and don't worry about it.

IF you somehow find you have "too much" carbon build up on your intake valves and top of pistons, there is a simple fix for that using just water..... plain ole everyday water.... I won't go into details because I'm sure I'd leave out a step or two but that's all that's necessary.

However, fuel treatments (as a rule) are not very expensive to use a couple times a year so just make yourself happy.

You can't be serious. Is this another myth from 40 years ago?

Hyundai does not recommend using fuel treatment if you use top tier fuel.

 

[homeofstone]

I use Techron about every 15k miles to help keep injectors clean. Never really thought about it removing carbon from cylinder head.

I guess they do every 7.5k miles.
And always if you don't use top tier fuel.
I am away from my manual though.

 

[RN2X]

They recommend it every 7.5k UNLESS you use top tier fuel.

 

[kn5owa]

The manual recommends an additive if you are not using top tier fuel and you have engine problems.

1. Problem #1 is that they say nothing whatsoever about what this additive might be.

2. To find out what a "top tier fuel" is, you are directed to www.toptiergas.com.

At the website, most major brands seem to be listed including Costco - which is not really a brand***, but what I personally use.

I will stay away from additives unless there is an obvious, demonstrable reason to do otherwise.


*** Costco uses multiple suppliers, e.g., BP, 76, Arco, etc.

I always used the Lucas brand..

Seafoam is the only one that actually does anything.

Seafoam is the only one that actually does anything.

Yeah, like void the warranty. I can't believe that anyone would put a product in their gas, that is supposedly suitable (according to Seafoam) also for the crankcase (or vise versa).

Fuel injector cleaners, do in fact help clean fuel injectors. It is not a myth. But that doesn't mean it will cure a badly fouled fuel injector.

Mark - you do know that adding a quart of diesel fuel to your oil and letting it idle for 20 minutes is incredibly good & healthy for it as well, don't you?

I've been using Seafoam in 600-1100hp offshore powerboat engines for years without a single detrimental result. The product as designed and if used as intended does about a good of a job of cleaning out crud from engine fluid pathways (sans coolant) as can be done without removing the motor entirely, taking it all the way down to nuts & bolts and hand-cleaning them with a brush and some mineral spirits and then re-assembling it.

You don't have to believe me - just talk to the folks in the industry who make a living as high-test, performanace engine chiefs. And no - I don't mean the fresh UTI grads at the Hyundai shop.

I couldn't say, but I absolutely guarantee that if Hyundai found out, and there was a problem with your engine, they would void the warranty, and Hyundai's voiding of the warranty would hold up in court.

I personally am not interested in old wives tales. I do have a rear view mirror in my car, but I try not view everything with it.

TLDR - Additives are still useful, just not as necessary. While cocktail reading, decent link at the end discussing this subject.


I might add, and I think it is important to remember, that most gas already has these treatments. As an example if you buy Exxon, Chevron, Valero, Texaco, Shell, or Mobil, they ALL have detergents (also all happen to be TT).

Additionally, the ability of your car to get over a "bad tank" (less common than it used to be, but 20+ years ago it was fairly common, especially at smaller stations that used indie suppliers...of which there are shitloads in TX) was easier for older cars. (I'm not Sith, so take that as generalization)

Hyperbole? Not really, for example, take a case where (and this refers only to unified pumps) a station may offer diesel but sells virtually none, ie, they go weeks, even months between fills (then why don't they just not fill it as high?...again, TX, we have some very weird fuel laws here pertaining to sellers), or it is a less than ideal batch of Mack Juice, that unified pump may spew varnish in your tank cause you followed the guy with the big ol truck. Newer DI motors, are more susceptible to what that can potentially do. Gilbarco (just one mfr, but a very big one) insists this is not possible with their design of unified pumps, but it has been proven numerous times and ways to be possible....youtube can be a real bitch for a major corporation.

There will always be a this is better than that argument, Mystery Oil sucks, Beryman Chemtool is useless, Seafoam will hydrolock your motor (I was hearing that crap in the early 90's for godsakes and it STILL persists), SI-1 is coasting on the Redline name (or redline has terrible batch consistency which has also been proven ridiculous and you hear the exact same said about Amsoil), Lucas is a sponser NOT a chemical MFR, and so on....

Lastly though, there IS a lot of snake oil out there, I'm sure we all remember the ZMax, DuraLube, and Slick50 suits. So if you feel the need, use a well known brand.

I saw the earlier link and have watched a number of his videos, interesting, somewhat controlled, but hardly definitive. Boroscopes are cheap, I have three and a lot of fun to play with. /takesbreath

VTOh, and about warranty denials, while this may occur, it has never occurred specific to Techron and that HAS actually shown up in Federal Court


edit - I'm new here, so just sayin, I'm not trying to WOT anyone into submission nor am I the smartest-guy-in-the-room, I'm just really verbose
