several things come to mind. there are just some factory parts the aftermarket cannot touch or do as well, period. however, if the facts are given by ind. lab test/even better real-world testing becouse on paper almost never is the same as in real use... I'd go with the lab. if the lab is a fourth-cousin-removed-sister-company to the product... then no. this is exactly what nissan wants... debates, no clear answer... can you imagine if all motor mfg's start this " our oil in our motors or you get noise/ problems" market? black gold I tell ya, oil that is. when you think of it that way... it sounds dumb. yet one would also think nissan just might know something... about a nissan motor!

the most likely is this new motor had some issues that were too $$$ to fix after made / or a recall and the oil solved the issue until retooling was done and a change was made durring the production run... someone inside forgot the record the lack of need after the fix now they are just ridding the extra capital the oil brings post production run. being a plant manager, that's what I would have done... but that is just MY thought.

 

If only there were a good answer to that question. Ignoring the smug obnoxious replies of some here, there is no right answer only opinions.

Personally I had bad results with Mobil1 and good results with Pennzoil Ultra. I have no intention of buying Nissan's oil. MY manual has no line recommending it, and I will not pay that much money for an oil that I would have to change every month and a half.

 

GC is German Castrol Syntec 0w30...think it says European Formula on the bottle...it's different than the standard Castrol Syntec...you can get it at Autozone...it does well in high performance engines

 

Looks like MSCA is a know-it-all that's been drinking the Nissan Ester Kool-aid...

I used Castrol Syntec for the first 2 oil changes and been using Penz Plat since then, and I've never had the ticking problem. My car also didn't need the ECU reflash for the ticking valve TSB. Might be a connection, might not. My Penz Plat UOAs have been better than G37 averages every time, so I'll stick with what's working better than the average(and Nissan Ester oil). "If it ain't broke, don't fix it"

 

I never once cursed, insulted you, or made any personal attacks. I disagreed with the bad advice you are giving people and even used the owners manual to defend my position of why you are wrong.

This forum is for enthusiasts and for people to help out people. I am trying to help out people and using actual data and references from the owners manual to defend my position.

I made a very valid point against your argument and instead of attempting to respond, you just ran in the corner and hid. I feel sorry for you if thats what it takes for you to "ignore" someones posts. If you cant handle being wrong or people disagreeing with you, then maybe you should ignore these discussions. If you keep up that behavior, your ignore list is going to fill up pretty fast.

 

if you ask me, never use something the dealer reccomends, especially if your paying them
