change oil in ford gt 2005

[HOOKED ON GT]

Im currently at the building oil pressure phase
Ive turned the key on... hit the go peddle and pushed on the clutch peddle and then crank on the start button for 20 sec.

Staring at the oil pressure gauge and don't see it move up in pressure.
Ive done this step 3 times and nothing.

Not sure what to do outside of just starting the engine normally.

How long did you let it crank each time? My first go, I think I held it for a very uncomfortably long time and nothing. Thought for sure I was going to kill the battery. Did it a second time and it finally built oil pressure fairly quickly.

I've been changing my oil annually since 2007 and I have never been able to get the gauge to register pressure despite extended cranking. Don't sweat it. Ten quarts, crank and drive.

I have always questioned the value of the "priming" technique with the FGT. It always seemed like a LOT of cranking over without oil pressure, whereas the pressure builds nearly instantly when the engine is started, so I concluded it was better to just fill things up, start the engine and watch the gauge.

 

[HOOKED ON GT]

I cranked like I thought the battery was going to crank out 20+ sec x 3

I just felt a bunch of GT bro hugs in those replies
Thanks for the reasurance

Sometimes when cranking the engine, the battery voltage is too low for the oil pressure gauge to "boot up." I confirmed this a long time ago using an external power supply.

ah... that makes a lot of sense- mystery solved. Thank you.

Where's everyone getting Motorcraft 5w50 these days? Cheapest I've found is $12/quart at O'Reillys. Sheesh.

I got it at Rock Auto. With their shipping it was cheaper than local sources.

About the same price as O'Reilly's assuming shipping isn't free. $12/quart it is, I guess.

Walmart runs specials on it fairly regularly. Not currently on sale, but still a tiny bit less.

link works BTW.

$150/12 quarts. And they're out of stock. O'Reilly still wins.

Agree on the fact that if you don’t see pressure build and you’ve put in the proper amount of oil, “you’re good.”

Couple of years ago we did the Takata airbag recall on three cars, and did an oil change on Two cars in one long afternoon.
Three of us converged on one guys house that had two drive on Lifts.
Ford sent us the tech for the airbags.
But only two of us were working the entire time. The Ford tech and myself.
Patience is a virtue.

So I'm betting beer was diverting the others.

Mine never primed. I cranked for 30 or 45 seconds and started. Instant oil pressure

I disagree. Your car ALWAYS primed... but the gauge just didn't register. Instant oil pressure after an oil/filter change is a sure sign of a good prime.

We're averaging 3-4 oil changes per week. Our best practice is a 15-20 second crank followed by a start. Always get instant oil pressure. Moral of the story: Just do the prime procedure with a 15-20 second crank and don't bother with the oil pressure gauge.

Yes, I concur that the gauge didn't register. Is that a sign of a failing gauge??? No other indications that it was misbehaving...

All is good. About 80-90% of the GT's we're doing, the gauge doesn't register. Our "routine" is to crank for 15-20 seconds. Stop. Then fire up and confirm immediate oil pressure. Very, very consistent.
