I'm glad to hear that you are not doing 2 year oil changes. I change the oil on my Z 3-4 times a year based on mileage alone.

Also, my oil changes cost ~$30, so there's really no reason to try and extend the life of the oil. I just picked up 5 quarts of Mobil 1 at Walmart for $22.88 the weekend before last.

:D

I luvs rusty's cat. :rofl2:

Did you guys see the new Captain America: Civil War trailer??? Spidey is back baby!!!

Do you change oil at less than 2,000 miles?

Again, I'm not trying to extend the life of the oil I buy. I only want to fully utilize the oil that I do buy, rather than pour unused oil into the eco-station's waste-oil tank.

My last comment on this thread will be after I pick up a Nissan oil filter, hopefully tomorrow, to report what the service manager has to say about the scenario I've already stated. I hope the thread is not locked until after I report what he says, because what he says may interest some owners whose vehicles are in a similar, short-summer-only, low-km situation to ours.

by may 30th it'll be #3 for me LOL

to add to the above response, I will only have driven roughly 3k km or just under 2k miles since the last change. I did one before storage in November. did another one shortly after pulling storage in march. doing another one in may before my road trip. and another one once I'm back. do I care about the frequency? not really. oh and total mileage put on between then and now is less than 5000 KM. :icon17:

I'm too A.D.D. to read through this thread I think... It felt like I kept reading the same crap over and over.

The best way to do that is with analysis. Short of that, all you can do is guess. If you don't do UOA, change often.

More like 5000 miles. I could increase it to 7500 miles or so because I do so much highway driving, but I drive the car pretty hard and prefer to err on the side of caution. Regardless of mileage, I would never go more than 6 months without an oil change.

Just consider the oil fully used once it's 6 months old regardless of mileage :twocents:

You are referring to a Nissan dealer service manager? What makes you think he's going to say anything different than what Nissan recommends? Not to mention most dealer employees are idiots. If he says anything other than 6 month oil change intervals for summer only driving, then he's probably just another dealer idiot.

:iagree: A used oil analysis is the only proper way to determine an appropriate oil change interval for your car.
