So I am absolutely excited to be picking up my VT Vitamin C on Wednesday, but I have one question. Fuel additives? There are so many. It's absolutely too hard to choose one. I have used STP on my Jeep Liberty before, however I never really noticed much of a difference. Is there really a specific fuel additive that does what it promises? Anything that reduces emissions, cleans fuel injectors and valves, better performance and mileage? Or is it just a myth? Please let me know as I drive 50km each day to work and will be using the engine a lot, so more mileage and cleanliness is a plus.

Cheers!

I never used those. I always thought it did nothing. How can a small little amount of that stuff diluted in a tank of gas do anything. I guess if you do it ALL the time. But if you use gas from a trusted gas station , you should be ok. I get mine from costco, they use an additive that is suppose to be as good or better than techron or shells vpower but you don't pay the extra bucks for it

Perfect! Thank You.

I actually forgot to mention if there is a specific gas station that anyone recommends that is best for the VT. Performance and Mileage. Thanks

in my opinion they did work for me on my mazda (fuel injector cleaners specifically), however the engine in the VT is GDI (gas is injected directly into the cylinder) so the valves are going to stay alot cleaner than the older style where they would build up fuel deposits on the intake valves. The GDI system uses more pressure to inject the fuel so i think that by design they should be fine for a very long time. So i don't think our VT would need it. Again im not a huge expert and havent really looked into the very specifics for the VT engine so i could be wrong but from my understanding of gdi tech is my opinion based on.

i noticed that when i filed up at Chevron i would gain about 5mpg average VS the Shell gas across the street. so from now on even though its 10 cents more a gallon it seems like its worth it to me. So experiment for yourself and see what works.

I live in ON, Canada and Unfortunately there is absolutely no Chevron station where I live. I have heard many great things about it and would've loved to try it.

The Turbo has Gas Direct Injection as do more and more cars on the road. You DO need additives but those come with any Top Tier brand of fuel. You do NOT need to add anything more and using a NON-Top Tier fuel then using an additive is not recommended. Go to Top Tier Gasoline to find out more.

Awesome!! Thank You for the information. It was greatly useful.

Costco uses top tier gas =)

If you fill up with ethanol enriched gasoline it is vitally important to add an additive (as Hyundai says) ever so often. Like every seven tankfuls.

The reason, although they don't mention it, is to keep the demons (caused by the ethanol) at bay and out of the fuel system of your car.

The demons being gasoline tolerant algae and fungi, which are prone to being encouraged to grow in the ethanol that's in the gasoline.

The only other problem that is common in ethanol enriched gasoline is a separation of the fuels into layers (called stratification) to which an additive helps prevent.

Run non-ethanol enriched gasoline and you have no problems such as I mentioned above.

Here is a web site that lists all of the gas stations that have non-ethanol enriched gasoline to purchase.

Very helpful Thank you :cool2:

There are so many additives. Which one do you recommend?

I agree! You go to Canadian Tire and you're standing in the aisle with all the fuel additives for at least 30 mins and is tough to decide which one to get. Does anyone have any recommendations?

I have used ethanol free in my VT quite a bit and can't say I noticed a difference although I know it's better for it. I always run ethanol free in my 4wheelers, chainsaws, lawnmowers, etc. It costs about a $1 more a gallon here. I'm sure small engine and boat shops love the ethanol mandates because it clogs everything up so well.

 

[Ricky-D]

Well, I don't like to recommend anything but I will say that on the Valkyrie forum, the additive most often referred to as the "best" is Techron.

I myself don't use it because I use non-ethanol enriched gasoline.

If you compare the costs between the two, non-ethanol gas and/or an additive, it's probably a toss up.

Whichever one is on sale in the flyer that week :wink:

Barromans B12 or Seafoam worked wonders on my Durango.. Next tank in the VT is getting some B12..
Note that I also use B12 to clean sludge out of my Durangos oil system.. Half a bottle in the oil, let truck idle for 15 min, do full oil change.. Absolutely awesome results.. I dont know if these engines have a sludge issue but this works great for those that do.. Does a great job cleaning injectors too.. But normally, whole bottle in the gas tank after a fillup. Youll loose 1-2mpg on that tank, but the reciprocation of results is generally worth while.

Never put much stock in the additives trying to play themselves off OMG SUPER BOOST NOS 1000000 HP MOAR OCTANEZ!.. The Octane adjustment over a full 13gal tank would be like .001

I hate to be "mr. Know-it-all", but during my training in Automotive Tech at UTI, I've learned that fuel additives really don't do anything at all. In the best situation, they sort of "sanitize" the cylinders. But since the VT's GDI 1.6 has such a high compression ratio, the effects are pretty much cancelled out by the next fill up. It does nothing to clean your injectors. They like to tell the tire kickers that to make them buy it. As long as you mainly use premium fuel, the injectors will last the life of the car. You CAN use regular. But, I recommend only using it if you're a bit tight on cash at the pump. Honestly, the only thing you'll notice from fuel additives is discoloration in the ceramic shells of your sparkplugs when you get them replaced (which is going to be more often in a Turbo than an N/A engine). I hope this was helpful! Congrats on your new Veloster

I did have a partly blocked injector on the right cylinder of my fuel injected motorcycle, and 80mls of fuel additive (scaled down for the small tank) cleaned the injector and got everything running as it should, according to the ecu scan programme running on my laptop. I only run premium fuels which are supposed to be high detergent but, obviously, an injector can get blocked.

The Veloster with extreme high-pressure common rail direct fuel injection will be different to a port injected motorcycle, and I doubt if the injectors will need cleaning and I doubt that the cleaning of the insides of the cylinders will last more than a tank or two of petrol. What I do with my turbo is run Subaru Upper Engine Cleaner through the inlet manifold prior to each oil change. This cleans the inlet tracts and inlet valves of any deposits built up because these parts of the motor are not washed clean by petrol, as would be the case with with a port injected engine. The Subaru Cleaner is used by a number of car dealers in my city for various models with direct fuel injection.

It is a different animal, but I use synthetic 2 stroke outboard motor oil in my Cummins diesel and it does amazing things to fuel mileage. I use about a quart to 35 gallons and have photographic evidence of 30mpg.

I have thought about using it in the VT but am a little concerned about fouling the cat which is not present on the Cummins. Although I suppose a fouled cat would be an excellent excuse for a new DP.

Upper cylinder lubrication and injector cleaning/lubrication are good things and gasoline is very "dry".
