...with 35000 miles on it...? and I have heard about SEAFOM or BG-44 as a good products to confront these types of problems,what is your advice about these products??,cause I have a little fear about put those things in the engine...thanks
build up as in engine sludge? if it is go to a mechanic and change your oil... i reccomend mobil 1 cause thats what i use itll last for 1 and a half years. i dont see how u having problems with an 07 tho. mayb ur switching constantly with different octane fuels? Its what ever but i think an 07 is still in warranty you can get it fixed for free.
I doubt you have a lot of sludge in an 07 Dodge unless you live in the north and make a lot of short trips or idle more than normal. We sell a ton of Sea Foam(so it must work). We also have this stuff called engine flush by Gunk. That the oil change places buy by the case.
