Re: regular oil
depends on how hard you drive the car, for me i redline every gear so synthetic is the way i went. got my first oil change at 1700 to syn. just had my second a few days ago at 6800. Only lost about 1/2 qt. of oil in the 3 weeks between changes.

Re: regular oil
I'm sure regular dino is fine, and after all, it's what the manufacturer recommends.
I think what's more important is changing the oil/filter on time.
There are many here who use synthetic (yes me too) and feel that it gives an extra measure of protection.
There are many here, too, who feel the regular oil is sufficient.

Re: regular oil
I'm not sure if the requirement has changed on more recent Coupe models, but on page 10-5 of my owner's manual (mine is an '03) it states "Infiniti recommends mineral based oils...."
I guess that could be construed as just a recommendation and not a necessity, but none the less it's there.
I find a lot of dealerships sell the synthetic also, so apparantly they see nothing wrong with it.
So long as they don't quibble over warranty work..
I'm sure regular oil is fine, and 3k changes are fine too.

Re: regular oil
The oil analysis results with Mobil 1 showed wear metal numbers too high for my comfort, lead especially, followed closely by iron.
I could always continue with M1 and simply shorten the interval, but I suspect that on a short interval of 4K or so, dino oil will protect as well as synthetic. The quality of dino oils have improved so much over the last few years that they can typically protect up to 5K miles or more. I'll be using analyses every step of the way to validate the oil use and interval I've chosen.
Additionally, synthetic oils can cost more than twice that of conventionals. If my UOAs indicate that dino will do the job just as well... why spend more for the same results?
I also switched back to dino support my habit. I'm hooked on oil analyses, so I wanted to see how the dino would fare in the VQ in comparison to synthetic.

Re: regular oil
My 1991 Nissan 300ZX has 163,000 miles on it on the VG30DE engine, and you ought to see the Blackstone that I just had done on it. Blackstone said "NICE ENGINE!" The car runs perfect and it doesn't drink any oil. I've used Castrol GTX regular dino oil and religiously change the oil every 3,000 miles. Blackstone said I could extend the interval up to 5,000 miles, but I'm going to stick with every 3,000. Seems to me that synthetic only has a benefit if you want to go more than 3,000 miles between changes. Infiniti recommends regular oil as well.

Re: regular oil
Castrol Syntec was highly refined dino (mineral) oil. Other synths like Amsoil and Mobil 1 are (and I believe always has been) truly 100% synthetic. That's why you'd see mention of GC (German Castrol) on the oil boards; apparently the Syntec from Germany is fully synthetic. However, I do not know for certain whether (American-made) Syntec's formulation has changed to fully synthetic, or if it's the same ol' stuff from a few years ago.
To find out specifically which oils are truly synthetic I'd check in with the oilheads at BITOG.
