when i was a frequent visitor to Miata.net (great place!) I heard that most modern engines fully break in after about 30k mi (i'd assume under normal driving). In magazines, you can find Long Term reviews that show better performance numbers after 25k~30k mi. I'm referring mostly to Japanese cars.
So, there's my reason for waiting til i got 30k mi to switch. (Mobil1, of course
)
i'm using 10-30w (SoCal), 3500-4500 mi. interval

So the people who do use synthetic, what positive changes did you actually NOTICE....did you notice a difference at all?
What kind of difference did you see?
Thanks again...i appreciate all the responses.

The running in period should be on a mineral oil to allow the bore particularly to wear in. I recon on an oil change during the first 1,000mls(after rebuild) and again at 3-4,000 intervals. So aim to be fully synthetic at 4-5k mls.
I cannot comment on the version 7 engines but on my STi 6 I run Motul 15W-50. If it is good enough for WRC cars it might do for my odd track and drag day too.
In Europe 5-30 oils are considered too thin even in Winter.
This car has full instrumentation and monitoring pressure and temperatures of several "recommended" oils has been interesting and has re-enforced my belief that thin oils can lead to problems, particularly if you run on track where very high temps are reached.
Editted to say that no improved running could be detected, no improved fuel consumption but improved an maintained oil pressures are evident right up to oil change time.

i would like to think it's due to Mobil1 (at least that'll justify the extra cost of Mobil1...)

I switched late; Mobil 1 5w-30 @ ~20K. That is when I decided to go to TurboXS Stage 4. There is no noticable difference, but didn't expect any. Synthetics don't break down like dinos, but still change about every 3K to 4K miles
On the forums "formerly know as i-club" some changed to synthetics at 1st oil change & a few as soon as they took delivery. There are enough of these cars running around now that they surely would have complained about problems by now. Ppl complain about everythingelse in the forums at the drop of a hat.
