I'm looking for an oil recommendation for my next OCI. Although it is still 4K miles away, I figure if I have an oil in mind then I can watch the ads and maybe pick it up if/when it goes on sale and save some money.
- The vehicle is a 2008 Nissan Altima Coupe 2.5 S with the QR25DE engine. It's still under warranty.
- The owner's manual calls for API Service SM, SAE 5W-30, Energy Conserving oil.
- I live in Southeast Michigan. The selected oil won't go in until September/October and will be in there through the winter until March/April.
- I generally drive pretty easy. I rarely ever see the tach go higher than 3000 RPM.
- My daily drive is 70 miles round trip with a 40% city / 60% highway split. But since I carpool, every other day the car is only driven 6 city miles in the morning to where I meet for carpool, and then 6 city miles back home in the evening.
- The engine has no known problems.
- I'll only use full synthetic oil.
- I run 6K OCIs which equates to 6 months.
- Walmart, Advance Auto Parts, AutoZone, Pep Boys, and O'Reilly are all near me.
Here's a history of my OCIs to date:
- Factory Fill, 0 - 4K miles
- Valvoline SynPower 5W-30, 4K - 10K miles
- Valvoline SynPower 5W-30, 10K - 16K miles
- Castrol EDGE 5W-30, 16K - 22K miles
- Castrol EDGE 5W-30, Current Fill
The only pre-disposition I have is that I'd like to try something other than Valvoline SynPower or Castrol EDGE, only because I've already tried those. (Both of them have been fine with no noticeable differences BTW.) I've thought about trying a 0W-30, but the stores mentioned above don't seem to carry much of a selection in that weight other than Mobil 1.
