Cleaning oil control rings C4 Cactus - impressed
Was buring more than 1L per 1000 mile (80000 odo). Poured this directly into each cylinder (50ml ish), left for an hour, spun the engine (spark plugs must stay out) and repeated addition and soak. Cranked the engine to clear fluid, spark plugs fitted, idled for 15 mins, oil and filter change, 500 miles later, hasn't used a drop.... Magic...
