Sea Foam

[gtaylor318]

Is it ok to put Sea Foam in the gas tank of 2013 Camaro Lt 2?

Why would you want to do that? Your cars still new shouldn't need to add sea foam unless you're having issues with the car. If it ain't broke don't fix it.

Sea foam rally won't help much in the gas tank as no fuel passes thru the intake manifold and over the valves, which is what mostly you need to have cleaned. You can spray the sea foam directly into the intake manifold. There are a couple good threads in this forum that cover this subject. The best thing to get for your direct injected engine is a catch can.

Spray it into the manifold

Correct. I will add that we are seeing more failed catalytic converters, bent valves from the large chunks of the deposits breaking loose and getting trapped between the valve and seat, and piston and cylinder wall scouring when ANY solvent based upper induction cleaning service is used on a DI engine. Never was an issue with Port injection as the carbon build up was minor and somewhat soft where it is major on these DI engines and is very hard and brittle causing the scouring. In the gas tank, most all additives are not going to do a thing as the fuel never touches the valves, but be aware of the potential damage to your engine if you have more than 20k miles on it and did not run a good catchcan.

I'm with you. Now for a PI engine like the LS3 and L99, a solvent based upper induction cleaner can be used with little chance of damage to the engine as there is only a limited amount of soft carbon built up on the pistons and nothing generally on the valves.

Seafoam is garbage

Care to explain based on experience? Or is your comment baseless?

If you use top tier fuel, and change your fuel filter as recommended, there is no need for Seafoam for the oil, fuel or upper valvetrain (valves)

If you do a lot of stop and go driving, neglect oil changes, buy crappy gas, don't change fuel filter, don't change air filter, Seafoam will help.

Broad-stroked, a 2013 vehicle, used regularly, properly maintained, needs NO additives.

I use Seafoam in all my older vehicles (94 ZR2 and 03 Cavalier), 2 cycle equipment, tractor..I have been using it for 15-16 years. Stuff works great. Pay no attention to the inflammatory idiot who posted prior.

I Seafoam about 2 tanks before oil change. Car has almost 47K miles and is running fine. I also run an Elite Catch Can.

I wasn't impressed either. Glad I didn't try it. That guy tries to debunk a lot of stuff. He has debunked most of those off the shelf additives, boosters, and what have you. Its a honda lol but it's something to go off of. If it does nothing for his honda it won't do anything for us.

I'd be more interested to see what it does on the valves. Carbon on pistons does not really affect performance. I suppose enough of it could create a hot spot.

I'd personally rather run a can of Seafoam or other upper intake cleaner every once in while than have a catch can just because I don't like crap hanging off my engine.

I assume your referring to a port injected engine which it is fine to use, valves on port injected engine do not build any deposits due to the injectors constantly spraying them with detergent fuel. Now, if your talking a DI engine like the LLT or LFX then do NOT ever use it. In the gas tank does nothing as fuel never touches the valves. Using it as an upper induction cleaning can cause damage due to the severity of the coking build up on the valves . Break those big chunks loose and we see damaged catalytic converters, scoured pistons, and in rare cases a large chunk gets stuck between the valve and seat and if the piston hits the stuck open valve, bent valves. Really need to differentiate what type of fuel injection the engine has. And for 2016 and up all GM gasoline engines are now DI.
