HOW TO: SEAFOAM (Motor Treatment) A 370z

SouthArk370Z · 05-09-2013, 06:42 PM

In my experience, these types of products seldom do any good and often end up causing more problems. If the equipment is dirty enough that cleaning the engine would be beneficial, there is a high probability of dislodging pieces big enough to plug oil galleys and damage bearing surfaces. If it's not that dirty, then why use a cleaner? Keeping it clean is a whole lot cheaper and easier than trying to clean a dirty engine.

Then there's possible compatibility problems with sensors, plastic/rubber components, and even the metals used in modern engines.

Not sure it's true, but wstar's theory about messing with the O2 readings and hurting the engine sounds very plausible.

There may be a situation where an engine cleaner would do some good, but, for most people, they are a waste of time, effort, and money. If the engine is dirty enough to need cleaning, then it needs to be torn down. If you do the normal maintenance on you car, you don't need to clean the engine.

I've used seafoam for years without problems. I wouldn't use it in the z yet since i still have low mileage. Most cars i use it on have over 130k on the ticker. I run a third of the can in the oil for a few miles then change the oil immediately since it thins it out. Another third in the intake manifold and the last third in the gas tank. It's helped a little on higher mileage cars restore some pep. Just my experience

This^ The only thing burning off is the SeaFoam. Its a waste on most cars and big time on direct injection engines. The Z does not need this if you are using a good premium fuel with a proper detergent package(Shell,Chevron) etc. You can also hydro lock an engine and foul plugs and burn out ignition and coild packs. Stay away from this product. It does not take off any baked on carbon deposits. It physically cannot do it. Physical valve cleaning is the solution for gunked up valves. Check any direct injection type forum for reality.
