Getting a bit off topic in the thread. I see no where does it say not to use synthetic oil. Could you take a picture or scan the page where you read this?

 

^I thought it had better endcaps? Meh. I don't remember... I buy nothing but PureOne filters now

 

Yep Cardboard endcaps and the stupid bypass. It just has thicker media. Still crap. Pureone, Wix, M1, K&N Bosch are all quality.

 

Page 9-5 of my 2004 manual - "INFINITI recommends mineral based oils." I don't see why using synthetics would hurt it.

 

M1, Pennzoil, Castrol are all mineral based oils. German Syntec is only 20% Mineral oil.

But, recommends and requiring are two different things.

 

What would be better, the fram tough guard or the oem Nissan oil filter for the v8?

 

lol. id have to check the esm and see exactly what it says as far as that. you arent supposed to use synthetic oil in ANY brand new motor during break-in period. my dealership uses synthetic-blend oil for oil changes and such......and we have customers that recommend mobil1. so IMHO.....it shouldnt be a problem. if you plan on using full synthetic......ONLY use full synthetic from now on! dont go changing back and forth to regular or synthetic blend from time to time......use it and stick with it or else you can cause oil pump damage. this is known to happen, now if it works like that on the vq....idk, but just do it!

 

This will provide better filtration than either of those:


OK, srsly though, neither one... get a Purolator PureOne in the larger size (M45?)
