November 16, 2006In my 96' GT im running 5w-30 in it. Every once in a while i will have my low oil light come on. Then when i get under the hood and check the dip stick, the oil is just touching the tip of the dip stick. I think that i might have so BLOW BY in the rings. Does anyone know if i could use a thicker 30 weight or mabye even a 40 weight to stop it?

November 16, 2006Is the level going DOWN over time?
I usually find that I need to add about 1 quart per 1800 miles on my SVT Contour. That was typical for many 5.0L Mustangs too.
But before we consider that... are you using the dipstick to determine how much oil to put in? If so, that's a mistake. Yes, that sounds really weird and wrong, but the fact is that 4.6L dipsticks (and 5.4L ones too) are notoriously inaccurate. Ford kept revising them to try to make it better, so there's 4 or more different possible dipsticks you could have... all wrong.
The right way to put oil in your mod motor is to put 6 quarts in, run it for a while to circulate it, and then mark where the oil level is. The engine was designed for 6 quarts.
If you're putting 5 quarts in it, you'll get the low oil light occasionally, especially if you park on a hill. The low oil light is only supposed to come on if you are a FULL QUART low.
I don't think I would worry about oil consumption yet.
June 2, 2007the low oil light comes on when you park on an incline, he goes through a quart every 2-3 weeks.were thinking it's valve seals

Valve seals: smokes when you down shift
June 6, 2007you should really run a 5w/20 for the 4.6-5.4 family of fe engines.the 5.0 can take 10w/30-10/40.the clearance's in the 4.6-5.4 are alot tighter than the 5.0-351 w based family.try 6gts of 5w/20 and note where on the dipstick tube the level is.then drive 1000 miles and reference your marking to check oil consumption.
