Have put 500 km on the new car looking for different retail oils that are readily available.
Have taken the advice of the forum members and will be going to a 30 weight synthetic at first logbook service: 5w30 (Castrol Edge) or 10w30 (Mobil 1). As expected, haven't seen a single 20 weight on the shelves. For me first logbook will be approx 6000 km (ie 6 months)
As far as I know, current factory fill is Toyota 10w30 SJ mineral. I am planning to change out the factory fill myself after the free 1000 km inspection and am not happy putting more SJ in there. Will probably be using Valvoline XLD Lo-Vis 10w30 which is SM/ILSAC GF-4 and very good value.
Valvoline should take me nicely until synthetic for the duration.
PS Nice little car
