If the owner manual specified 7500 miles OCI with synthetic, then you should not use dino. If the owner manual specified 7500 miles OCI with dino then it is okay with dino, if you use synthetic instead of dino then you can extend the OCI to 10-12k miles.
 
depends on how you drive, if you drive mostly city, short trips, towing, lots of idling then for sure change that gunk out every 3k-4k miles regardless of make with dino.
 
All the vehicles I have owned and been around have two different service schedules, one for normal use and one for severe use, such as towing, city driving, etc. Read your owners manuals they are a wealth of information.
 
We have had no issues going to 7500 mile OCIs on dino. Thing is, syn gives an added level of protection, so why not use it has always been my frame of mind for the most part...

sludge-prone vehicles are another story...

Yes, that was me.

I average between 7500-9k on conventional 5w30 in my Saturn. After nearly 100k on this schedule, there is still very little varnish build-up. However, the oil consumption does seem to skyrocket after the 4k mark on every oil fill, which may or may not be an issue with synthetic.

So, as far as I can tell, conventional oil can last 7500 miles (or more) on certain non-sludge-prone engine designs.

I would not be able to sleep at night if I went 7500 miles on conventional oil.
 
The owner's manual for my '87 Camry recommends OCI's of 10k miles under "normal" use conditions (5k OCI's under "severe" conditions).

No distinction is made between conventional or synthetic. I would assume that Toyota assumed dino since the car was manufactured in the 80's.

I bet they even had Pennzoil in mind.

I'd never do 10k miles in my Camry. At 10k miles, all the oil would have leaked out.

Please note:
Beemer= BMW Motorcycle
Bimmer= BMW Automobile

As for buying used, my wife's X3 has over 80K on it and the sole non-scheduled repair has consisted of a passenger seat SRS sensor which was replaced under warranty. Her prior car was a 1997 528iA; the person we sold it to now has over 220K on it and, aside from a water pump and thermostat, the engine has not been touched. Ditto for the slushbox.
YMMV, but that's been my experience with just two of the seven used Bimmers that I've owned over the past 26 years...

Subaru used to recommend 7500 miles/dino with their turbo cars(WRX/STI,Forester, Legacy/Outback) and basically back peddled to 3750 miles for all turbo cars.
