Hi, I fitted a Flashlube catchcan at around 30K and was then using the 30 oil and have been using the 40 oil for last 3 oil changes and noticed no difference with the amount of oil the CC collects. It was surprising though the amount of vapour that this thing collects over a few thousand Ks, all that crap is going through your turbo, intercooler and finally your intake so I would definitely recommend a CC if you want to keep your car for more than 100K, cheap insurance at approx. $300 spend.
