Engine additive effectiveness: SEAFOAM: works for mild sludge and carbon deposits when added to oil. Also clears fuel system deposits via intake (through vacuum line) — this is its most effective use for carbon on intake ports (port injection engines). TECHRON/BG 44K: excellent for fuel system and injector cleaning. PEA (polyetheramine) content is key ingredient. ENGINE FLUSH: use with caution on high-mileage engines — can dislodge sludge deposits and clog oil passages suddenly. Better: just more frequent oil changes. TRANSMISSION FLUSH additives: generally avoid. These products work best as preventive maintenance, not cure for serious mechanical issues.
