Did a VOA on this oil last year. Click here for link
This is a summer car and I ran this oil between April to November last year with a Tokyo Roki filter. I redline the engine quite frequently, but I let the car warm up before I start thrashing on it. Most of the time it's short trips and it sees the highway only on occasion (not more than 10km at a time). I asked Blackstone if I should consider going up a grade because of my driving style, but they think it looks fine so I'll stick with 0W20.
I know that silicone and break-in metals hang around for quite a while in these engines so I'm not worried there. It's actually not as much as I've seen on other reports of this car, but I've already changed the oil three times so I'm sure that's got something to do with it. Because the TBN is still good I'm considering changing the oil once a year before I store the thing away for winter instead of every 6 months like I do now. Seems like a waste of money to change it that often...
I'm quite pleased with the report and I can't wait to drive it again in a month or so!
