What type of oil is reccomended for 4th gen Maxs? (10w30?) I just bought mine used and need to get an oil change. The guy before me used mobil1 synthetic.

 

I use Castrol GTX 5W-30. Always have and never had any problems. I have posted a similar question previously and was told that using the Castrol is fine especially if you change your oil regularly. Some on here swear by the Mobil 1, but I don't know if it's worth the extra money. However, if you don't prefer to change your regularly you may want to consider going synethetic.

 

Nissan specifies 5w30. Conventional oil along with a good filter (such as Nissan OEM) should be good for 5000 miles. Synthetic oil is good for even longer, at least 7500 miles.


As for brand, that's a personal choice. Most any API approved oil is fine.

 

escellent- thanks
How often do filters need to be replaced w synthetic?

 

Depends on drain interval when using synthetic.....A synthetic can go 10k between changes, so any standard oil filter should be replaced at 5k. However, the "pricey" filters such as Mobile 1 or Purolator PURE ONE (the $10 ones) should be able to last 10k without changing.

My oil analysis spreadsheet proves this is possible.....
