Hi guys!
Bit late here but still relevant I guess..
I’ve had my awesome ‘06 XC90V8 almost a year and after some research decided on 5w-40, my reasoning being the far hotter climate than the car was designed in.
Have always used Penrite, and PAO based when feasible/practical but now have recently researched Nulon and found out via a supposedly independent study it may be even better!
So will give it a go..
PS. Agree that the 5w is more suitable than the 0w for the hotter Aus climate too. 0w is really only for freezing or below 3 degrees celsius temps.
Though the -30 might be too thin at our higher than usual operating temperatures in frequent 38 degree plus summer days especially when sitting in traffic with engine bay temps reaching boiling point. ??
So anyway how have you guys found the oils for yours so far?
