1AZ-FE Rav4 150,000km This is a full synthetic GF-5 dexos 1 Normal city commuting with the odd long trip Last time I used Mobil Super 5w30 and at 8000km TBN was 1.7 I don't think I'll safely get 10,000km out of an SN GF-5 style lube with the driving I do. UOA

Other than Lead(is gas in Australia leaded?) the report is great. The Nitration and Oxidation numbers show that the oil did really well in resisting thickening(virtually none) and combined with the fact that the TBN was 2.12, I am willing to bet that you can easily take this oil all the way up to 12-13,000km's with no problem. Very impressed with Penrite. Thanks for posting as we dont get many Penrite UOA's at all!

The silicon is pretty high at 20 ppm. Check your air filter and probably change it. Consider something like Mobil 1 0W40 which has a much higher starting TBN at almost 12. Charlie

Thanks for the replys I only use regular unleaded which can have up to 150ppm sulphur but no ethanol. I did a further 1000km and then changed it out.

Stephen, How many kays does your RAV have on it and what year model/engine? I use the exact same oil in my Forester yet I have some very different results to yours after the first service. I know there isnt a comparison (different engines and all) but it may help me to understand my results. I think I will use your UOA lab next time.
