Oil consumption is a known "issue" with the GT350's. Whether or not what you're experiencing is a "normal, allowable" amount I don't know, I'm just letting you know it's not uncommon for GT350's to consume oil.

I know someone that’s going through the oil consumption test with his GT350 now. He thinks it burns a quart every 750 Miles... The dealer said that a quart every 500 is the amount of oil used before they can do anything. It’s a fact the vodo uses oil.

Assuming your track day is road racing, I am not surprised. I do not race anymore but when I did I was never surprised that running the car hard used oil.

LOL, my FE engine in the Cobra uses oil just sitting in the garage!

I was always taught to check any motor's oil, even my lawn mower.

Just curious... but shouldn't you warm the engine up to temperature and then shut it off and let it sit for 15 minutes before checking the oil level?

That sucks. Sure hope the next GT500's (hopefully named just Mustang Cobra eventually!) don't have an oil consumption issue.

That is what I did. Just edited the waiting part out of the video.
Roger that! It just appeared as if you started the engine for 30 seconds or so, shut it down and then immediately checked the oil level. Hell if I did that on the Vette the oil probably wouldn't even register on the dip stick in the sump tank!

I do not believe anything is wrong with the engine. Oil consumption under high load conditions like a track day is perfectly normal for engines in general. If the consumption is not occurring under normal driving conditions I would not worry about it. Even LS engines experience the same issues. I see it all the time. Under high stress, high temp conditions and high crankcase pressures oil can make it by rings and seals. A quart of oil gone and about 2-4ounces in the catch can is acceptable.

Oil consumption is a very well known and documented issue for the Voodoo. There are alot of guys getting engines replaced over it.. Our 350R burns some as well, as does our 16 Coyote.. If you spin any engine at 6-8k for an extended period of time, you're going to burn oil. Ferrari's are known to burn more than a quart every 500, and is perfectly acceptable. I'd rather not have a grease monkey touch my car than get a new engine over it burning a little oil when beat on.

That’s just it though.....the engines drink oil without any rhyme or reason....doesn’t matter if beat on or not.

Where you’re wrong is thinking that it’s happening without “any rhyme or reason”. It’s by design. Not saying it’s designed “to” burn oil but to allow the engine to perform in the manner in which it does, burning oil is a byproduct. OEMs have been fighting the fuel economy war for over a decade now. One of the largest consumers of fuel economy we see these days is caused by internal friction. So to give you an engine that produces the power the GT350 does and turns the rpm while also allowing it to get good fuel economy while cruising, the byproduct is oil consumption. Lighter weight materials within the rotating assembly, cylinder wall finish RA, RPK, RVK, RK, ring tension, and even valve guide conditions all equal to and engine the produces great power, spins high, good fuel economy and burns a little bit of oil between changes. One of my engines would burn a quart in one night of drag racing but also possibly only a quart on regular street driving. If you only knew what the industry is pushing us to do. Now remember this isn’t the same type of oil consumption from the 90s. Back then if your engine burned oil it was because some was wrong. Those days are behind us. If you can reduce your consumption to a pattern. All is fine.

Obvious post is obvious - just disgruntled this is the ‘top dog’ Mustang
