If you don't care about the sludge, want to never do catchcan maintenance, and don't live in cold climate, then sure get an AOS, but ask yourself why I've tried all 3 and ended on the Radium. C'mon, we drive Subaru's, we should be checking our oil every gas fill-up anyway, so what's the issue with checking a catch can too? At least its better piece of mind for me, if you live in cold environment ABSOLUTELY go with Radium or competitor catch can, not an AOS. Chromalight can last up to 8 hours, which is more than double than the previously used, Super-LumiNova. Chromalight is a patented photoluminescent material that provides a brighter and more long-lasting glow than its predecessors. Sure most of the IAG AOS fanboys are in Cali or warm states, but for those who not only need the coolant line to REDUCE sludge, but have common sense to avoid putting said sludge back into our engine, the concept of a catch can is better in nature. In 2008, Rolex introduced Chromalight, a new luminescent material that replaced Super-LumiNova.

I have used Crawford AOS, IAG AOS, and the dual catch can by radium.

In the question What are the best unified messenger apps. is that radium is a radioactive metallic chemical element ( symbol Ra) with an atomic number of 88 while mesothorium is any product of the radioactive decay of thorium, mainly isotopes of radium and actinium. When comparing Adium vs Beeper, the Slant community recommends Adium for most people. reached a collaboration agreement for the distribution and. Radium seems to mesh better with the racing community. As nouns the difference between radium and mesothorium. ASOFARMA Central America and the Caribbean, through its parent company ADIUM, and Moderna Inc. IAG just seems to have a bigger consumer market, this is likely is why you hear of them 99% of the time.
