Loc: Colorado Hi Buster,

Thank you for the kind words and welcome. I don't visit this site much and am sorry not to have responded sooner.

I don't really make recommendations on oils, since it seems you could run just about anything and be alright with a normal drain interval. However, here is a comparison chart I have made for VQ35DE engine oil analysis. I considered over 100 UOA results from this engine when calculating the average wear amount for each metal per brand. Every brand and weight are averaged, and then the wear is normalized for mileage across all the different brands and weights I've collected. There are a number of older oils which are not on this chart because of formulation changes, such as the older RP and M1 blends, and some G5 PP blends as examples. What is reported here are the current formulations which are on sale, and how they compare to the collected averages for each wear metal. Red cells indicate more higher than one SD from the average, green cells indicate one SD lower than the average wear, and gray cells indicate wear within the SD.

Most of the UOA's are from 350Z owners, all of whom have the VQ35DE engine and have been keeping a running log of their UOA's on a 350Z site. A couple of G35 owners and VQ Altima owners, like Nederlander75 two posts above, have also been kind enough to contribute.

For you 350Z guys this may be old news, but I found a lot more info on Oil from "Resolute" on that site. Here is the URL since there was quite a bit of information consolidated in one place - VQ Oil Analysis and Info - MY350Z.COM Forums


AK - I hope this is a legal post.
