But think about it, How else can you loosen coked oil? I think it actualy helped the rest of the engine. One type was not recomended for turbo engines. The other did not specify. They were different ingredients. the one I used was mostly acitone. You only Idle for 5 mins before changing your oil. I let it drain for an hour and then ran a quart of clean oil through with the drain plug out. Then new filter and and mobile 1. Didn't really think I had much to loose since it if is harful to the turbos, I had to change them at that point anyway. What do you think is bad about it IYO?
