How often should I change my oil if I'm using synthetic?


Asked by Jun 08, 2015 at 04:51 PM about the 2014 Nissan Altima 2.5 SV

Question type: Maintenance & Repair

I use 0W-30 synthetic oil and change it every 7500 miles. Should I decrease it to every
5000 miles or increase it?

I use Mobil1 and change @8,000 miles. 10K is acceptable. 5k is a waste of money. You are just right. Use a quality filter

Personally I don't use synthetics, but that is my choice, looking at all of the stuff about it FordNut is right about the mileage interval. I can remember that when synth's were just getting a hold on, the oil change interval was no different than conventional oils. So some progress has been made. But still it all depends on how and where you do most of your driving.

Thanks Fordnut. And I can understand your reasoning for not using synthetic tennisshoes.

Generally, follow the guideline in the Nissan Owner's Manual for your car. It also depends on your driving style and where you live, which is also mentioned in the manual. It appears that Nissan is suggesting 5k miles on its oil changes for newer models. For the first oil change, use 5k as recommended then you can adjust it as you drive. If you push the car more aggressively or live in harsher environments (SW with high hot heat or N like NE with harsh winters), then you may wish to consider oil changes sooner than later. I've used Full synthetic and it has lasted longer and better >5k upon changes. But since I lived in a hot region and now live in a cold weather in NE, with moderate commuting, I have oil changes every ~5k, but don't worry that much if I push it ~<7500.

Mobil 1 2014 altima Nissan says 10k if you are strictly synthetic Mobile says 15k As a former engineer I can tell you that you can look at your oils condition right on the dipstick.Synthetic oils dont breakdown, conventional so you are really looking for dirt( air intake etc). Since my 2013 has 108k I have changed oil every 15k for the first 100k now will change it every 10k .Nissan designed the 2,5 ltr spec for a synthetic oil, yet Nissan dealers and many owners use reg oil ( 7K is fine with today's metallurgy )
