when do you really need to change the oil in these g35's? I have a 04 sedan g35x. I am changing it around every 5k miles. I dont see the point of every 3k. Couldnt you even wait until 7500 miles? Also is it really needed to get oil changed at infiniti dealership if you do not do it yourself? They charge about $50 for regular oil.

 

Too be on the safe side I get mine changed every 3-4K. Why take the risk of saving $50.00 and later my engine starts acting up (Wayyyy tooo costly). Anyways why do you go to the dealer, I get my oil chage from NAPA, $25.00. AS good as dealers. Unless if you put synthatic...

 

Dealership is garbage, your on the right path with 5k though.

 

You can go anywhere you want to get your oil changed. Go to a Nissan dealer if you want to save some cash.

I wouldnt go 7500 miles on regular oil. 3-5K is a normal change interval for conventional oil depending on your driving habits and conditions. If you want to go longer switch to a synthetic oil.

 

compare the cost of syn oil changes at the dealership to the cost they would charge if you bought your own syn oil. walmart normally has mobil1 for about 26$ for a 5qt.

 

Infiniti recommends the oil to be changed at the most every 7499 miles.

I change mine every 3750k, no matter what. I also check the level at least once a week.

 

Every 5k here.

Super easy to keep track of and it's a perfectly good compromise between the recommended severe conditions 3750 mile intervals and the normal conditions 7500 mile intervals. Been changing the oil at 5K on my cars for well over a decade now, never had a problem.

3K is old school IMO, unless you truly are driving within the severe condition criteria.

 

I switched to synthetic and change every 5k-7500k miles. My driving is normal conditions.

 

I change mine every 3,750 miles or 4 months whichever comes first, and I do my own oil changes on all my cars. Been doing it for the last 6-7 years.

My opinion is, if you spent good money on a car that you own, the least you can do to take good care of it is by changing the oil yourself and not paying some random monkey wrench do it for you.

 

i change mine every 1000-1500km cause of the stupid warranty i have to do it every 4 months, and i don't mean miles i mean KM

 

I change my oil myself. It's really a trust issue as there are few people I trust to work on my car.

I usually go every 5K. 3K is more of a result of marketing vs actual need, but i agree that oil changes are cheap and it doesn't hurt so why not right?

If you do a lot of highway driving, you can go longer than someone who does city driving.

If you are really concerned, you can have an oil analysis done by blackstone labs and it will tell you how long you can go

 

Absolutely no way to determine your oil change interval w/o an analysis. Unless you go frequent like a 3-4k change.

 

That is way too small of an OCI. That's an oil change every 1000 miles. NO oil on the market today needs to be replaced that frequently unless you are tracking every single mile...you are basically throwing your money away. No warranty issue requires that frequent of a change, if it does, you are getting ripped off.

My OCI is currently at 6k, I will be doing a UOA from Blackstone when it warms up a bit, currently running Amsoil SSO 0w-30, should be good for 7500 at the very least.

 

Get mobile1 at walmart for $26 and I buy a bunch of bosch oil filters from autozone whenever they are on sale for a couple bucks. I know I can go longer, but I change every 7500 miles. No problems so far at 83k miles on the car. Did the same for my last car too with no probs.

 

i swear to god i'm buying a house with a garage and a heater for it when the market gets better, i can't sell my condo in this and not take a hit...

then i can go back to changing my own oil year round instead of paying all winter...
