hi just decided to check my oil and bought some 10w-40 semi synthetic. i decided to check the forum before i used it and i did a search. most people suggested 10w-60. my question is if i use the 10w-40 will it cause any problems or should i take it back.

cheers

 

p.s. i have an imported auto TT

You will get lots of opinions here. The handbook says the recommended viscosity number for the widest ambient temp range -20C to plus 40C is 10W30, 10W40 or 10W50. I use 0W40 full synthetic last 2 and a half years. I have a high mileage and get a little hydraulic tappet noise when I start it cold. Others here swear by 10W60. I guess the slightly thicker oil to get the 60 rating might have benefits on the track or with a rattly engine.

 

As long as the 10W40 oil you have is a reputable make its OK.

 

My full Nissan service history showed semi synthetic all its life till I got it.

I use Mobil Super S, 10w40 semi synth, always have. never had any probs on any vehicles

best using fully synthetic - Magnatec is only semi-synth
