The use of synthetic vs conventional oil comes down to what you think is best for your truck. Some have switched from conventional to synthetic then back to conventional because their truck ran better before the switch. Some have switched to synthetic and not gone back.

I have never heard of anyone switching at 130K. I am personally a synthetic user, however if I had 130K on my truck with no problems I would be inclined to stick with what has been working.
I switched around 130k, but thats b/c my truck doesn't live in Texas anymore. Actually I don't know what the PO used but I chose to spend the extra $$ per gal. My truck likes the syn alot better.
me too in so cal. i can see the the pros and cons from both sides but i see more benefits with our motor but it's not like 15w40 with 5000k mile changes is doing harm.
