Hey Guys,

Can someone tell me why the manufacturer - NISSAN says not to use synthetic oil in the g35? I have a 2006 sedan..

Does anyone also know a credible place to buy OEM parts. I need a rear and front bumper and a passenger, rear quarter panel.

Thanks!!!!

 

I have never heard of this. Where does it say that?

Majority of the forum runs synthetic.

 

isnt nissan premium oil synthetic??

 

Do you have the rev up engine (manual trans)? They might say not to because it is more likely to cause oil consumption. I know that at least the first few oil changes shouldn't be synthetic on the replaced rev up motors.

 

I too would like to know exactly where you read that???

I found out that some manufacturers actually recommend only using synthetic oil.
I've heard stuff about "breaking in" an engine on conventional oil before switching to synthetic, but my cousin's G8 came with synthetic oil right from the factory

 

Only one reason I could think of would be if you have a Rev-Up motor, oil consumption.

 

we need the_coupe's say on this since he isan infiniti tech

 

read the owner's manual. it's in there. at least it's there for my '04.

 

^ hmm, I know the dealers near me sell 120 buck Synthetic Oil Changes. So If it was advised not to use synthetic then why do they sell it?

I been using Syntec for over a year now with excellent wear results and no problems.

 

^ wow that's a lot, even for a dealer.

 

^ i asked the dealer that question when i first bought my car. the service dep't was advertising synthetic oil change packages. when i asked why they were advertising this when the owner's manual stated that synthetic oil was not to be used the service tech's eyes glazed over and he had no answer. nor did the service manager, predictably.

i use synth as well. always have. i still don't know why the manual says this.

 

They probably just want an excuse to void your warranty.

 

I use conventional fluid in the engine anyway.....but synthetic everywhere else.

 

That's odd - why?

 

^He's said before that he changes the oil every 3000mi so he doesn't see much point in running synthetic with oil changes that often.
