I have a 2004 WRX and I seem to average about 1 quart of oil use between changes 6000km (3728 miles for you non-canuks). I’ve spoken with the dealer about this and they said that’s “within tolerance”. Whatever that means. Needless to say I’m not sure I want to take their word for it.
So, is that a normal consumption? Is there something I can/should do to decrease it? The limited experience I have with other cars is that they did not use any oil between changes.
The other question I have is about Synthetic oil. A couple of people I’ve spoken with suggest I switch (and I’ve done a bit of quick searching and it seems like a good choice for a “high performance” car to increase life span, ect, ect), but my car already has 32000km (~20000 miles) on it already, is it too late? Should I not bother? Is my car already “adapted” to regular oil? I don’t really mind paying the little extra for synthetic I’d just like to know if I should at this point.
