Refer to the owners manual. I think they recommend 5W30. I would stay with the $1.50 qt oil and just change it every 3000 miles. Works for 99% of the population.
I always go synthetic and change every 3000 miles. I figure its an extra level of protection and much cheaper then a new engine.

I've heard that if it's an older vehicle, you shuld keep to the dino oil, and not sythetic. Reason is synthetic molecules are smaller and will find any holes in the engine and you'll have a leak fest, unless you first initially put sythetic from the begining.... I'd say stay with the 5w30 dino

Only use synthetic oil if the engine has always been run on it. Otherwise I highly recommend on using a quality 5w30 dino oil.

Synthetic Blend would be the best. Keep those leaks down!

Hi pepperman
A quart per 700 miles is a little below Fords acceptable usage figure of a quart per 900 miles. How many miles do you have on your engine? Do you puff a little smoke at a stop sign? it could be time for some valve stem seals, which may dramatically reduce your oil comsumption, my 92 TC with 129,000 miles barely uses a quart per 3000 miles.
Allthough high oil comsumption isn't much of a problem in itself other problems may occur if left for too long such as blocked EGR channels, carbon build up it the combustion chamber that can cause pinging and damage to the catalysts.

Dereck,
The car itself has over has over 170,000 miles on it, i got it from a friend of mine it use to belong to his uncle and they told me that a couple years before i got it someone put a factory brand new engine it, so i am not sure exactly how many miles are on the engine. I make sure that i change the oil every 3 months or 3,000 miles, I do have a check engine light that comes on every once in awhile and i will be changing the spark plug wires soon the car shudders when i get it up to speed. the car came from Las Vegas. :give :Beer :L

It depends on what they did when they replaced the motor. The "whole motor" isn't everything under the hood. There are still things that may have 170k on them.
