I just got my oil change at about 1750 miles and it took me about a month to finally decide on Mobil 1. One of my biggest concerns was carbon build-up. (The one major reason I didn't choose Pennzoil Ultra because of its NOACK rating) So my main question is, since no oil will keep the injectors completely clean, what is the best course of action to keep them clean? Right now my best idea is "Seafoam", but I have no experience with cars so I don't know if that is too hard to do, or even safe for my suv.
Carbon Build-Up? Seafoam?

Much worry about a completely non issue. These are fuel injected computer controlled emissions engines burning unleaded fuel. Not a 1920's,1930's,1940's,1950's,1960's,1970's 1980's carburetor engine running on leaded gasoline.
Cold starting problems, extended cranking, flooding, stuck choke plates are items of the past.
Check the ingredients in Sea Foam. Coleman Lantern Fuel, mineral oil/baby oil, gasline antifreeze, perfume and CO2 for fizz.
Sea Foam is slop designed to separate fools from their money.

I'm a little confused by your statement that "no oil will keep the injectors completely clean". No oil goes through the injectors. Just gasoline. Seafoam is added to the gas tank and will clean the injectors but it's unnecessary in modern engines unless there is some other issue going on.jamesvl said:
From what I have read, because of the Crankcase Ventilation being routed to the intake, vapors from the oil are deposited on the intake valves.Black Granite LTZ said:
Yea, that is my biggest concern, if the benefits or "said benefits" of seafoam are going to outweigh any damage I could do to my car.gar187er said:
most modern engines have the vent going to the intake....you can easily bypass this by getting a breather valve...jamesvl said:
something like this:

it will let the crank vase vent to the engine bay, and not back into the intake...you can find them in autozone, or the like....$10-$15.....much cheaper, much better then seafoaming your engine....and it will ease your peace of mind out oil on the intake valves
Of course it's going to smoke. Feafoam contains mineral oil. Pour a bottle of baby oil into any gasser engine and it's going to smog because it can't fully burn heavy oil.
Anybody ever think about what all those unburned long chain hydrocarbons are going to the cat converter?

When Seafoam is never on your mind...

Seafoam is a great product and I've used it on all my vehicles, older and newer. It's not necessary on a vehicle with low miles such as yours, but after about 35-50k I'd do it. All my engines have run noticeably better after using it. The only risk you run into is fouling out your spark plugs if you pour it straight down your intake, but I've never had that problem. A full seafoam treatment includes adding it to your gas, oil, and pouring some down your intake. Read the directions carefully and you'll be fine.
What possible gain is there pouring a mixture of mineral oil, isopropyl alcohol and Coleman lantern fuel into an engine? Have a look at the Whmis sheet. That's all seafoam is plus a little CO2 for fizz to appear exciting.SS#1531 said:
The so called soot and carbon you think is being "cleaned out" . The smoke and carbon from the tailpipe is the partly burned mineral oil in the seafoam. It isn't crud being knocked loose from inside the engine.
Have you looked inside a modern fuel injected gas engine? They do not carbon up. The cross hatch in the cylinder walls is still visible at 200,000 miles.
You would be netter off taking the $$$ and instead pouring a good grade of ethanol down your intake.
So if Seafoam is a no-no (per some of you) for the new I4 DI engines to stop/quiet pinging/carbon, then the oil fumes from the crancase will make a mess on the intake. Since no fuel spray is washing it away, per old system, it will very definitely gum up. That said a catch-can will definitely be a wise investment.
Fuel injector cleaner will clean the injectors in these modern DI engines but will do nothing for keeping the intake manifold plumbing clean.

I think that it is a very bad idea to start pouring things on the engine of a newer car , Seafoam or whatever . These engines are computer controlled and engineered to maximum efficiency and low emission pollution levels ... spark plugs are replaced after 100,000 miles so that alone tells it to leave it alone . They run very , very clean with no need for additives . If you put oil on the tank the most likely scenario is kissing Good bye to your expensive Iridium spark plugs

That video is a HOOT! Looks like something we would do back in the day just for kicks and giggles.

I suggest using Tier 1 gasoline as suggested in my manual, anyway. Carbon, then, should not be an issue.
The manual says (In my 2010) that if you don't use Top Tier gas you can use a Fuel system cleaner. Somone posted in this forum that the GM one (As well as BMW) looks like the exact package that Chevron Techron cleaner uses
For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of GM Fuel System
Treatment PLUS, added to the fuel
tank at every engine oil change, can
help clean deposits from fuel
injectors and intake valves. GM Fuel
System Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
