I want to start using mobil 1 full synthetic, the car has 110k and this is the second synthetic oil change I will be doing. My question is how often should I change the oil? I heard 4k (i drive all city). The thing is i drive about 8k a year. Is it alright for the same oil to be in the engine for 6 months at a time. Also, should I put in any additives? As far as i know, maxima's aren't known to burn oil, even at high mileage???

thanks in advance for any advice

- '97 5spd

 

From what I heard, synthetic oil supposedly *lasts* up to arount 15k miles, which seems insane to me, but I would change every 5k. Not sure about how long time wise though. NO ADDITIVES! syn oil and regular oil has additives that help clean everything already.

 

6 months should be fine, but if you want to, do it every 4 months or something to keep it nice and clean.

i used valvoline full synthetic and change it at 4000 miles. that is what nissan recomends

 

Do not rely on time to calculate when to change your oil, within reason of course. Mileage is a much more accurate measure of when it should be done.

 

I was wondering where you saw that, since I read the manual and it mentioned nothing about which brand of oil to use??

 

Thanks everyone for your advice!

 

I change my oil every 2500 miles with Castrol Full Syntec 5w-50, Thats good Shiet!!!

 

5w50 I wouldn't use. I rather use 5w40 or 0w50 but not 5w50.
