I'm thinking about changing to synthetic oil, could anyone point me in the right direction on what kind is the best to use..

 

amsoil 5w-30, or mobile 1

 

Ok thanks..

 

either of the one listed but mobile 1 is cheaper..

 

also make sure you get a good filter, oem nissan use a paper filter. look at amsoil, mobile 1, wix, k&n for filters

 

i would go with castrol syntec before mobil 1

take a look at all the used oil analysis reports on my350z.com

castrol outperforms mobil 1 constantly.

 

but yeah, wix filters are good

 

these are all from VQ35DE motors


you can see syntec > mobil in most categories, especially iron

 

isnt the german castrol supposed to be pretty good?

 

yes it is, you can see from the oil reports that all wear levels are really low, but it can be hard to find... so i just went to walmart and bought a 5qt jug of syntec

 

so when looking at those charts, you want to go with the oil w/ the lowest Number in the bottom row where it says sustained viscosity right?

 

Hey thanks for all the info..i hear alot of different oil to use, i just didn't know but u guys pointed me in the right direction..

 

It's nice to see a compilation,
But that sample set is just too small to have any validity.
Most of the units only have 1 or 2 samples.

This would be great with a larger data set.

 

Go to bobistheoilguy.com. There is great info about oil and oil related products.

I use Q Power full syn. 5w-30 is $18 for a 5qt jug at chinamart.

I change my oil at 8K with a quality oil filter. Currently I am using Purolater Pure One filters, but along with the P1 the Wix, Napa Gold (made by Wix), Bosch, M1 ($$$), Amsoil ($$$), and K&N ($$$) are great choices.
