How well does seafoam work in gas on the V engines? Anyone notice any difference in the way it runs or is this stuff not recommended?

Some folks swear by it. Me personally I see no difference running with or without it. I do however make sure there is plenty in the fuel before winter storage. I think it's more of an occasional cleaner than an everyday use kind of thing.

I put one ounce per gallon in my VS650 when I know it will not be ridden for a month or more, usually this is only during the winter.

I also use it like carb/injector clearer on any motor vehicle or the lawn mower when they seem to be not running right. Since it has a shelf life of about one year, and the Vstar only needs 4 ounces out of the 16 ounce bottle, it gets used up in one vehicle or the other within a year.

I get the sense my bike in the spring seems a bit off on that tank of gas with the seafoam from last december. It does keep the gas from degrading, but Im not sure if it also throws the engine or ECM off just a bit when you use it. Even with a fuel stabilizer old gas is still old gas.

I have also put it in the crankcase about 500 miles before an oil change a few times, once on my Vstar, and once in a car that burns a lot of oil. Dont know if that accomplished anything.

I have never heard of seafoam harming anything.

The problem with seafoam is it will phase separate. You noticed an issue after it sat up. What I recommend is "stirring the tank" when it is going to sit up. How ever you want to do that is up to you. I am lucky enough that my stuff does not sit long so I only have to use a FI cleaner as a cleaner not as a fuel stabilizer. What I do recommend since it does not separate when mixed properly is BG Products. I use it in every vehicle I own. The local rep has proven to me it does not phase separate and sea foam will. We mixed both per recommendation in my shop in glass jars and I set them on my counter and did not touch them for 2 months. The sea foam started to separate within a day (hours actually) and the BG did not over 2 months. Sea foam is a GREAT product and I have used it. I am not slamming it. I am just giving my experience.

NGM - that brings back memories

when I was a kid my father put antifreeze in his car, and then put a bit of the mixture in a little glass Bayer Childrens aspirin bottle, and hung it from the hook on the garage for the clothes line.

Not sure exactly what he was thinking, maybe if it got cold enough at night the bottle would break, and he would then know his engine block was cracked?!

Since aspirin bottles did not have child proof caps in the '60s, and antifreeze is deadly poisonous, it was probably not a good idea....

I probably won't use it in my oil but not knowing the history of this bike, I am sure nothing has been done cleaning wise.
I added 5 ounces to a full tank of ethanol free gasoline and rode to work today being it was in the 40s today.(35 this morning)
Was not having any issues but figured could not hurt giving jets and venturis a cleaning.

Well after running 2 gallons of the treated fuel that I can definitely confirm that the foam of the sea smoothed out my idle. Before it was a little jinky going up and down at certain times.

One thing all good fuel cleaning products do is to dissipate water in the fuel. Here in Houston we have extremely high humidity which condensates in the underground tanks. Then it finds it way into our gas tanks. The water forms rust in your tank and engine will miss trying to fire on gas mixed with water. I average at least 1250 miles a month, about 8 tanks every month, so the odds are I'm getting a lot of moisture in my tank. Since I've started using a fuel treatment about twice a month it keeps everything in great shape. I used to fight poor runnability issue all the time until I stated regularly using fuel treatment. No I don't run cheap gas, major brand from busy stations. Any way, that's my 2 cents.

I run a seafoam-laced tank through mid-season every year.

Don't really see a difference, but feel it's a big reason why my bike runs like a top year in and out with only basic maintenance.

For winter-storage I used sta-bil, but also think the key effect is the same (i.e. kill off moisture)

PS - Your bike is not as nice as you think and you're asking too much for it... Sorry, just had to throw that in since it seems to have become my 'rep' of late...

We have Phillips 66, Exxon and Chevron here for top tier gas. The one 66 station is ethanol free but you usually pay a little more. Worth it imo.
In my car, I filled up at a chevron. Ran pretty good. Smooth idle. I filled up at Wal-Mart once because it was cheaper, and could totally difference. Was much more sluggish and do not have the detergents you need to keep engine clean.

I am not trying to sell my bike. Perhaps that was meant for someone else?

I throw a couple oz's every fill up. I did notice improved performance in my carburated bike, I suppose with FI, the ECU adjusts for it.

Make sure to use any fuel cleaner, stabalizer, whatever according to directions. Too little and it does not do much. Too much and you can actually poison your gas. If you pull out your plug(s) and they have an orange tint you have too much additive in your fuel.

I used to have to put in seafoam or other injector/carb cleaning additives once a month to keep my FZ1 running well (Carburated).

Then a guy at work suggested I try higher quality gas from Chevron instead of using Costco.

After 2 tanks (I commute and generally fill up twice a week) I no longer had cold start or idle issues. Now I only fill up at Chevron, Shell or 76, I don't trust Costco or Arco or any of the other cheap options.

I am now a firm believer in higher quality gas for all my vehicles. It has been 2 years since I swapped to Chevron and have not needed to use a injector/carb cleaning additive in that time frame.

FWIW...

My youngest uncle - he's only 12 years older than me - spent his entire career as a petrochemical engineer. Worked 40-some years in refineries in Texas for Amoco, Texaco, Shell, Arco (AKA BP) and Valero. For the last 20 years or so he's been the 'head dude' in charge of gas quality & blending for Shell, though he's retiring imminently.

What he said, consistently, is that it's all about the same for 87 and 89 octane stuff. The only real difference is in the 'premium' 91+ levels where the additives really are different and the care taken is also different. THERE you will see a difference between name-brand and generic gas. FWIW, he'd also tell you to buy non-ethanol if at all possible, and that IF you want to buy premium gas, Texaco is the best blend and Shell a close 2nd. He once explained to me what "techron" is, but lost me about 30 seconds in... something about 'covalent polymerized' something or other... He never worked for Chevron but seemed to feel they were top quality. He did not have much respect for ARCO/BP quality: best I ever got out of him there was between the Brits being cheap and the Californians obsessing over meeting emissions, they never did do it just right.

Places like Costco, Giant, Turkey Hill, Sheetz, etc. that don't own their own refineries are buying from the big boys anyway... You may be getting amoco one week, shell the next, valero the following, getty the next, or a blend of them through a middle-man distributor. Certainly you're getting a 'blend' of them in the station's tanks quite often. But note that the big boys do NOT sell their own premium blend to the distributors/generics, they sell a different 91-93 to them that meets octane, but without as many additives, detergents and such.

He didn't regularly buy premium gas for his everyday cars. He did buy it for the 'toy' cars he kept with high-compression engines that need it. He did recommend running a tank of premium through a regular car 3-4 times a year just for the detergents. I asked if that didn't foul up the 'computer' and he said 'not enough to matter.' Never thought to ask him about Sea-Foam. Maybe I'll ring him up and see what he's got to say.

He did also regularly say buy gas at a high-volume station. To him the key difference was how long the stuff sat in the tanks ESPECIALLY with hydrophilic ethanol involved.

Just saying.

Plus 10% ethanol is b.s.
It comes out to about 15% from the cheap places.
I try to get ethanol free for my car but the station is 17 miles away so when I am in town where the station is, I fill up.
If I can't get ethanol free, I will get top tier recommended octane fuels.

I have heard similar stories before. I wish it was easier to find non-ethanol here in California, but it is not.

FWIW my anecdotal evidence is all on 87 octane.

I also ran 91 in my STI and primarily purchased it at Costco for 12 years.... never had any issues with that car. But after seeing the huuuge difference in my FZ1 and similar issues in my Vstar, I will not go back to the cheap guys.
