Im about to do my 3rd oil change and im thinking I should change to synthetic now. Currently at 6300+ miles. Should I change over now? My gut tells me yes, but wanted to hear from owners who have changed to synthetic.

 

I'm switching over next oil change (2nd oil change). 4k

 

im switching at 3k

 

I switched at 13K.

I decided to err on the side of 'waiting to change to synthetics until the car is well broken'. I don't know whether this is the truth or just myth.

It seemed easier to follow Nissan's written recommendations in case there were any warrantee issues that cropped up in my car.

 

Switched at 3K

 

Ok, I just switched over to Mobil 1 synthetic and its definetly smoother overall. I can especially notice when rev-matching/downshifting.

But overall, it is definetly much smoother than when I changed my oil the other two times.

 

I will be switching to syn at my third oil change at about 8,000 miles.

 

hmmm... might do the same when i reach 6k... couple hundred more miles to go

 

I switched to Mobile 1 at 4700 miles and plan to do a 5000 mile oil and filter change, or at 6 months, whichever comes first.

 

switched @ around 1100 and change near breakin ..no probs at all runs like a champ

 

Switched at 960.

 

I just switched at 3900.

 

I change all of my MV's that do not come from the factory with Mobil 1 as soon as I can, perhaps a few hundred miles. Then every 10K miles or 1 year, whichever comes 1st.

 

Switched at 1190 miles to Mobil 1 Supersyn. Check out my drain plug.

FYI - Mobil 1 comes from the factory in Corvettes and Dodge Viper so there is no bad/good time to switch to the syn stuff. The sooner the better. I switched at 1000 miles. It is all I use, expect for Amsoil in my other toy, my VStar 1100.

 

Switched to mobil 1 5w-30 @ 3500miles.

anyone tried the 5W-40 grade? or is it 0w-40

 

What filter are you guys using? I was planning on getting K & N oil filter.

 

I just did synthetic switch @ 4800mi...can I wait more than 3k mi for the next one? Sorry to gravedig on this post...

 

I am using Mobile 1 5W-30 and factory filter at 5000 mile change intervals or 6 months, depending on driving conditions. Lots of in-town driving, I will replace oil and filter earlier.

 

Awaiting 7500-8000 miles.... will go synthetic unless some new revelation (about adverse effects) presents itself on the board...
