i have questions about oil changing for 2006 350Z
after i bought my car for used, i did oil changing at the local Nissan Dealership. They recommended me 'Valvoline SynPower Full Synthetic 5W-30'
1. How many miles usually require to change for 'Valvoline SynPower
Full Synthetic 5W-30' ?
I changed engine oil at 20,789 miles and the sticker on the windshield
says that next oil change is at 24,530 miles. I have 24,630 miles on my
odometer and its already passed over 100 miles . Its like 3,800 miles i
drove after last oil change. I heard some people said that you can
change Full Synthetic Engine Oil between every 4,000-6,000 miles.
So should I change oil at this time or later?
2. I searched good engine oil for 350Z, i saw Amsoil, Mobile1, Royal Purple
and so on. Does
'Valvoline SynPower Full Synthetic 5W-30' is good enough for my VQ35 ?
3. Is that possible that you buy some different brands such as Amsoil, Mobile1 , or Royal Purple from anywhere and you bring it to any local Nissan
Dealership to change it for you instead of what they have.
Please answer my questions
