    Hi everyone, There is a thread on here where a confirmed oil engineer/scientist backed up a claim that was made that increased oil change frequency may lead to an increase in carbon buildup for GDI engines. There has been a lot of back and forth and not here to further that debate. I just...

    The GC's that I have been buying from Canada haven't changed for the last few years. Then I went today, I see new packaging. The lot # and stuff remain the same, but just wanted to make sure from you oil gurus that its just a packaging change. Thanks! New photo pics:
