also weight of oil is important. 5-30 is recommended. but thats at sea level and/or non extreme temps. you want 10-40 during the summer and 5-20 in the winter, where the extremes are. ie arizona 100+ new york 30-. thats just what ive read. could be wrong.

You should be fine with the 10-30, but 5-20 or 5-30 might be a little to thin for a high mileage motor in the summer months.

yeah youll be fine with 10-30. i just read in an old magazine that this guy would switch to 5-20 in the summer months to 10-40 in the winter.

all depends on where you live like panda said i live in phx az and almost every one i know runs 10w 30 or 10w40 in any truck. these are heavy bricks with weak motors. they get a lil toasty here. my car and truck temp gauge said 113 today and summer is just starting. ford uses doesnt want to put a list of different weights for every season and every climate and or state or even region for the matter. it wouldnt fit on the oil cap lol. plus i run synthetics in every part of the truck if you are unsure of synthetic technology consider this. a: look at what your tranny fluid is b: most high end cars come with it. why would the put crap into a motor that costs atleast as much as your truck does new?
