Yeh changed it yesterday and seemed as thick as i would expect.Like u said, oil pressure was good the whole time i had it in the engine for 5000kms.Maybe its just doing a good job of removing contaminates to look so shagged.I really want to stick to a 10W40 as i think this is a good viscosity for our engines so im just seeing if there is anything in this price range thats better.A lot of people rate 4100 turbolite so i would like to know whether this so called penrite full synthetic is as good as the Motul.As for the price,i still paid around the $50 mark or else i would have gone something else.
