are there any problems when changing the oil from regular to synthetic? my max has 111000 miles on it so i thought it might help the life of the motor.

 

This should probably be in fluids and lubricants.

I have went back and forth with no ill effects.

 

Do two applications of AutoRX before switching. See www.auto-rx.com and www.bobistheoilguy.com

The AutoRX will clean your engine internals and ring packs, rejunevate your seals and minimize the potential for leaks which you might otherwise experience when switching to synthetic oil at your mileage.

 

yeah should be no problems after that although i would not switch back from synthetic to mineral oil, fr33way you said you have switched back with no problems? you must be one of the lucky ones

 

No leaks perhaps?

My tranny is not so lucky, my MT90 sweats just a bit

 

I recently went in for a oil change at a Nissan Dealer. I have about 150K on my 96Max. They (without my knowledge) put in Castrol Synthethic blend motor oil in the car. It's cost about $45 dollars for a oil change using that. I was wondering if it was worth it especially since it is such an old car??

 

uhh yea u can change back and for with synthetic and regualr.. it even says so on the bottle
