I haven't used any fuel system cleaners on my 08 Accord, but are they safe to use? Anyone recommend something that actually does work and make a difference? I heard about Seafoam but there is no way I can pour that in the tank. It doesn't have the long top like other cleaners. Thanks.
 
I've personally used chevron techron 2 separate times on my accord, they didnt seem to do much. I'd be weary of using seafoam, read some awful stories about it. If your engine is healthy thats good, seafoam will work great. But on older/worn engines that carbon buildup can actually help seal any grooves or small openings, by removing it you could potentially get compression loss, resulting in premature wear. I would just change the fuel filter and take off and clean the injectors for peace of mind.
 
I use B12 chemtool. If you use any cleaner, you need to drive your car like mad. Driving at 2-3k RPMs won't do much, WOT (wide open throttle) runs will clean out any build up.

In the VCM equipped cars, running a can of fuel injector cleaner will actually make the engine run better because it will clean out the piston rings thus reducing oil consumption. Many including myself seen a difference.

Fuel filter? You mean the whole fuel pump assembly because the filter is built into the fuel pump. Unless you have symptoms of a bad fuel pump, no need to change the fuel pump.

The J-series rarely have problem with fuel. Adding the fuel injector cleaner will clean out the injectors (obviously) to some degree.

It's unnecessary to drive mad when you are doing this, as it is not required to do so. You can just leave it in park and rev the heck out of the engine until all of the carbon smoke comes out. That's what I did and many other Accord owners did on youtube.

Please explain how using fuel injector cleaner "because it will clean out the piston rings thus reducing oil consumption."

This is difficult for me to understand.
 
Redline, Techron, some others use PEA which is a synthetic cleaner. Results depend on the strenght of the product. Redline is stronger than Techron as BG44 is stronger than Seafoam. The best thing to do is get an injector service done where the cleaner is directly put into the fuel rail. Results vary depending on product used. Some shops run Seafoam up the rail, Walmart uses Gumout commerical strength ($20 service). Best is those that use the Delco (GM) injector / top end cleaner, cleans out more of the carbon.You can change the fuel filter but you have to remove the fuel pump from the gas tank.

Driving it like mad will put load on the engine and the cleaner will be more effective. Revving the engine in park sounds foolish, puts stress on the transmission and will piss off neighbors. Here chrisfix says to drive the car after you added the seafoam, I don't know what videos you watched. Sure when you start the car up the first time you're not just going to let it idle, you give it a few revs (3-4k RPMs not redline) and then drive the car hard.
Watch from 4:11. According to him, thats what the instructions say to do.

Maybe I didn't explain it thoroughly.

On the VCM equipped cars, the piston rings will get lodged with carbon/oil deposits overtime and the piston ring will allow oil to seep into the combustion chamber. Adding the cleaner will dislodge the build up and will help seal the combustion chamber better and oil consumption will decrease. Keep in mind you might need to run 2-3+ tanks of fuel injector cleaner to notice any difference.

I watched the videos of people owning 6th Gen Accords. And 2 out of the 3 videos just revved and the 3rd video just drove. I didn't saw Chrisfix's video at all, since I was looking for a 6th gen specific video.

Get a funnel. Seafoam, Techron, et al are ok to use.
I bought a funnel and a 16oz of can of Seafoam. I poured it into the gas tank and then filled it up with Chevron 91 octane. How soon can I notice any results, assuming the fuel system did need some cleaning. My 08 Accord only has 54k miles. Thanks.
 
Depends on how gunked up your injectors are. People that use top tier gas ( that contain detergents) see less if any improvements, others may see more of an improvement. I notice a difference in about a 1/4 tank. So you used a can of seafoam with techron (that is what is in Chevron gas).
 
You don't need fuel cleaner very often, really. As long as you use quality gas for Top Tiers, you shouldn't have any issue to begin with.

Oh, and don't drive your car like a granny all the time. When you are going onto the highway, floor it. The occasional hard driving can clean out a bit of carbon.

With 8th Gen V6 AT, make sure you have the latest revision of the VCM update. This supposedly helps. If you are very paranoid, you can just disable it.

As for the Seafoam in the intake/vacuum line thing, I heard that water can do the same thing. You would suck the water into the vacuum line slowly like you do with Seafoam. Water is a lot cheaper, of course, but the Seafoam spray is a lot easier to use.

The typical procedure is 1/3 in the gas tank, 1/3 in the crankcase, and the rest goes into the vacuum line(although they have a spray that does this now). 1 can in the gas tank is a bit too much, but you should be fine.

You shouldn't really notice anything. You may get a tiny MPG improvement, but that's really it. It's mostly preventive.

Rev the engine to redline in P/N/neutral is bad for it. There is a difference in revving the engine up with and without load. Driving a car to redline is nothing to be afraid of, but there is a good reason why AT Accords won't let you rev past 5k RPM in P.

Just find the closest highway ramp near you, and there.

THANK YOU. Someone finally understands the right points!

Thanks for the info. I bought my car used and I don't know what kind of gas the previous owner was using, and it did belong to an elderly person. So it's very unlikely that he revved up the engine. I'm going to Disneyland tomorrow, and I'll be sure to rev it up on the way there. :grin

This.

What I used is this little guy here. I think it was cheaper than this in store. Ignore the threaded part, just pull it so it's far enough away from the car and pour. Keep a paper towel nearby so you don't drip it onto the paint when you remove it from the fill. Most gas stations usually have some blue towels on/above the washer squeegee tank trash can combo.

My usage of seafom in prior vehicles is different than others. I'm either using a old set of spark plugs temporarily or I'm replacing the plugs and the oil after the seafoam was done. I would also spray it into the spark plug hole just enough to coat the top of the piston. Spray as in this one here.

I've got one of these:

https://www.walmart.com/ip/FloTool-Multi-Purpose-Funnel/16889146

The neck is so narrow it will go into the tank filler easily. The top having the extension on one side you put on the bottom. It will prevent any drip-down from the bottle of additive onto the car side. You can pretty much just pour your additive from the bottle normally and funnel will whisk it away.

I was getting them for like $0.50 $0.60 locally and tossing them afterwards. I have one of those in black that is super long for manual trans fills kinda like this.

That is an old wife's tale. I used sea foam as early as just a few months ago at 220k miles with zero issue. That is a 10+ year old engine. Do it properly is the key.

Techron DOES NOT do anything at all, it's been proven by ChrisFix on youtube.

There is no more need to change fuel filter, that is a practice on much older Accords.
