Last time the oil was changed on my car was around 6000km ago, the next oil change mileage sticker was set for 164000km, now I'm at 164087km, so I've been considering doing my oil change next weekend or so.
My model is a 2000 Grand prix GT.
I've went around to the local auto part shop, and they told me that 5L of oil and a filter would cost me around 40$ taxes included, first of, is that a good price?
Second of, what brand of oil should I use? And third, I know it says 10w-30, but I've seen that last year on the winter, the car had little trouble. Since on the winters, the temperature can drop as low as -40C here, and on the summer go as high as +45C. Is 10w-30 alright as they recommend it for the N/A 3800?
As of the oil filter, what brand would be the best to get?
