oil question

I just bought a 1994 ford thinder ird and the oil despritly needs a change
i ve never owned a V-8 and i want to know if i should use 10w-30 or 10w-40


K~

yes i am a newb

I've been using 10W30 for the past 6 months, but then i read in my manual, that the best thing *recomended* is 5W30-for ALL temp's.

I have a 95 V8 bird, great cars.

Use 5/10w 30 if it has a lot of miles on it you might want to move to 10w 40, but thats up to you. I run 5w 30 in mine.
