Use of Synthetic Oil on Nissan Cars

**Olive Drab** · February 15th, 2004 07:50 AM

I just want to share the memo I got from our fleet management:

Below is a portion of the official statement of Nissan on the use of
synthetic oil on Nissan cars.

" ... it has been their policy that use of synthethic oil is not
> recommended for Nissan vehicles. The reason for which is some synthetic
> oil have higher acidity compared with conventional mineral based oil
which
> tends to wear out the engine gaskets and oil seals causing oil leak.
>
> Engine related problems caused by the use of synthetic oil will void the
> warranty."

What particular synth oil would that be in question? Is it applicable to older or newer engines? :?

I have a friend whos been using synth on their Nissan Sentra for quite sometime (5 years?) and they still have no engine leaks. However, i know of a Cfeiro thats been using synth and it encountered leaks. The SA told me the same thing before when i wanted to put Synth in my Frontier... honestly, i wanted to whack the oil on his head because it was the first time that i've encountered such back then... :D I was told by other SA's that if you use synth, chagne pa rin every 5K.

All nissan cars? I haven't noticed any problem on my Terrano. Been using full synthetic oils since my wife & I bought it. Kindly specify which Nissan models mustn't use synthethic oils.

no matter what oil u use. u should change the oil regularly. especially for diesel engines. sludge buildup is the worse thing you want in your engine. if you seldom use you vehicle (sunday car) and would not change oil with in 6 months then go synthetic. i was told that regular or premium oil has an expiration of 6months after first use.
