Guys a lot of comments from you on engine oil but my original post was more related to transmission oil and the change in behaviour of the shift criteria, and this was my theory on the change in fuel consumption. good to hear some of you backing up my fuel consumption figures, all in the way you drive no leadfoot acceleration!!! On the other point of service costs after the capping runs out, they do get expensive, you need to talk with your service Manager and get only done what is necessary, if you look at your service book you will see there is a lot of fluff, I got what I thought a reasonable deal from my dealer doing just this, given that my wheels have only done 40,000km over 5 years this was a bit easier to negotiate, but I will always do this from now on. the last service cost me around $500 some earlier blogs suggested charges up around the $1000.
