oops, hit enter. anyway option
A. high quality synthetic with 1 yr OCI (12K miles) and 6 month filter + top off with Oil analysis or
B. just do Dino blend with filter change at every 6 months 6000miles?
Would it be better to just use the dino blend and flush more contaminents out?

It all depends on how frequently you drive and the driving conditions. In harsh condition synthetic is better (i.e. -40F, forced induction), in short trips, frequent change in dino remove more water and fuel dilution.
I recommend a search in the UOA and see what others are using that give good results.

Also what engine you have.
well I would like our cars to last a long long time (toyota tacoma 3.4L, ford focus zetec) The focus has great oil analysis with amsoil XL 5x20 but the truck only did ok with amsoil. I was just contemplating whether it was worth 100+ dollars to do both the oil changes with synthetic (plus UOA) vs dino and more frequent changes or heck even dino and 6 month 6K mile changes. It seems most of them will go that long. Main reason Ive been going with synthetic is the cold Ohio winters.

I do 3K with dinos -- 4.5K with syn-blends & 6K with synthetics. A syn-blend for 6K should be analysis-tested. Reason-being is some oil manufacturers only use around 10-15% Group 3 in that blend.
If you are gonna go 6k on a blend do one analysis of it, and make sure whatever brand you choose is gonna work for that long. Some blends won't last that long under certain conditions, or your motor might not be liking the specific oil, kinda like the amsoil and your toyota.
I think 6000 is too long on dino. Can you handle 4500mi/4 months?
On Toyota passenger cars synthetic is best, but I don't know about Toyota truck engines. If the 3.4 is a passenger car engine you should stick to synthetic.

The 3.4 in my '01 Tacoma did very well on M1 10W30 for 10,000-mile drains. There was comfortable reserve left in the oil at that mileage, but that was an easy number to remember. It was a super-severe-conditions farm pickup (SERIOUS dirt, very heavy towing & hauling, tons of low-speed 4WD work in the field), though that also means the oil was up to temp. most of the time.
Sounds kinda like you are trying to avoid frequent changes.... and need winter startup protection.
Mobil EP 5W30, might do the trick.. but i don't know if it meets requirements for warrenty or not.

I vote for C....3 months 3000-4000 miles with a quality dino. 6000 miles is too far to drive on dino oil IMHO, and while some synthetics will survive to 12000, i'd certainly feel nervous going that far. Regardless of how good your oil is you will still have contamination due to fuel and junk in the oil that nothing but an oil change will solve.
