IMHO, I would be very resistant to use Seafoam......
Seafoam is a "Highly Corrosive" product and isclearly spelled out in the MSDS....something I would not have any desire toexpose to fuel injectors, sensors (including O2) & hoses of any type. Thereare those that will state "Used it for years & no problem", andvery true, but it simply violates every basic OEM specified maintenance/repairprocedure & law of chemistry in the books.....
No mfg including domestic & imports (including BMW,MB, Porsche) advises using any product like this (or similar) for any servicework on a fuel injected system. Documented damage goes back decades. There is lot of things that many people do to their engines,that is well document "Not to do"..............like I said, it'sbasic chemistry........that which we were all taught......with any product likethis, always read the MSDS.....
Seafoam contains
1. Paleoil......cheap refinery distillate (Why somebody would fog their cat and o2sensors with plumes of lubricant is beyond me.)
2. Napthalene......whichis dry cleaning fluid, an Aromatic which means it is a "toxin"affecting directly the liver, kidneys, spleen, etc.
3. Isopropylalcohol......not good for an engine (a small percentage of alcohol typically) andthe rest water
Sea Foam Sales Company - SDS
As listed under "Other important hazards", It alsohas "teratogenic" properties......Meaning there is an effect uponyour DNA...meaning you are ok but you future kids come out "screwedup", cell structure abnormalities, cancers, etc....and yes, you aresucking this in when it dumps out your exhaust pipe....or if you are drivingdown the road to clear it out, to your neighbor whose behind you....and thereis "no cure" for this.
Listed under "Hazardous Combustion Products"(meaning when its burning), it produces sulpher oxides (just what youwant....feeding sulpher particulates into the cats) & phosphoruscompounds.....this is not even close to being "good" for any plastic,o-ring, metal (like pistons, piston rings, residual that might bypass thepiston rings and make it into the oil, e-sensor, the honey-combs inside thecat's. While the MSDS does not spec the ph of the product, if you measure theexhaust at the point of discharge, you'll crap in your pants when you see theph change…..and for those who may think that the engine combustion will burnall this up....remember, poisons are destroyed at 1,800 degrees and toxins aredestroyed at 2,500 degrees F......not even the cats are close to this.
Using the right oilwith the right compounds in it is much better and safer!
