Xavier, This is just one guys opinion but I would be careful using Rislone or Bardahl in your engine until you determine how badly the sludge build up is. I have used Rislone many years beginning over 40 years ago in many of my cars and think very highly of this product. If the engine is clean there is no problem but if the engine is dirty with old oil sludge buildup this product will dissolve this old crud and may cause more problems than if simply left alone. Over the years I have seen engines that ran relatively fine until this product was added and after the old crud was dissolved the engines became noisy and burned oil more than they did before the Rislone was added. If the engine is clean inside I would agree with Rusty that it might be a good idea to quiet lifters and help keep the engine clean but if it is a very dirty engine then you may be asking for trouble. Sometimes it is just better to leave things alone.
