Recently acquired 95 Neon with the Chrysler 2.0 SOHC engine. After an oil change it started consuming oil at about 1qt/1,000 miles. Exhaust is stinky and the oil smells burnt on the dipstick. I picked up a can of B12 to do a piston soak and I’m wondering how much do I use per cylinder? How long do I wait? Do I do it twice before I clear it out or is once enough? Where is that burnt smell coming from? I haven’t poked at the PCV system on this car yet but I’m planning on it
