You don't need anyone following you around - if you're using that much and carrying it around by the case, then it's PAST time for an overhaul.
WTF is happening to my oil??

You're not using synthetic - at the rate you're using it, you'd have started complaining long ago about the cost of synthetic - $3.50-$8.00 a quart.

Yeah Im saving for my rear end, then doing a H/C/I combo on another stock 5.0 motor so I can keep driving my car while I do the H/C/I and then drop it into my car.

I thought I had an oil useage problem also when I bought my 89 new.But dealer said a quart every 750mi was normal.Something about forged pistons.

A qt. every 750 miles is not what I'd call normal. Mine doesn't move a drop on the dipstick between 3000 mile changes - about 70K miles on the bottom end. Dry as a bone underneath too.
Aliate - the numbers you refered to (10w40) are the viscosity of the oil - a measure of how it resists flowing. 10W40 is a multi-viscosity oil. At low temperatures (around 0 degrees) is flows like a 10 weight oil; at higher temps (around 210) if flows like a 40 weight oil. They were developed so people could simply run one weight of oil year round. Both synthetics and regular dino oils come in different weights - so, no - 10W40 does not mean it's synthetic. The W means it's rated for winter use.
