    What kind of driving do they tell you to do? Mixed highway/city/redline...not kidding.

    MIne was burning 1 qt per 500 miles with spirited backroad driving when I sold it. But if I did highway miles only it did not. I went 1000 miles with nothing'ish burned. But I didn't want to do grandma driving on the highway.

    (I hope I didn't miss this question...)

    Has anyone had an engine fail for any reason that was using Amsoil for all/most of its life?

    I did backroads and highway. A few redline pulls but not that much. I knew I was was over the limit just by my own oil measurements. They got me at 1 quart per 125 miles......new engine came in, I dropped it off on a Friday and got it back by Tuesday. They did a few before mine. So the tech was good at it!

    I spun Rod Bearings #1 and #2 at 7000 miles. Changed to AMSOIL at 1000 miles. Oil consumption started two months before failure at 1000 miles per quart then dropped to 500 miles weeks before failure then 250 miles days before failure.

    Amsoil is all I ever used and both engines used lots of oil.

    I know this was posted almost a year ago but H3298 was my car. I bought it from a dealer in Wisconsin and had it shipped here. The car was indeed a buyback, but not due to oil consumption - nor did it have its engine replaced. In fact it didn't have any engine issues at all and it never required oil. It was bought back with 983 miles on the clock due to a an extremely poor warranty paint repair.

    I have the owners kit for it and would like to find its current owner.

    H3298 is on the left and H3460 is on the right. IMG_20171121_194811.jpg

    This is scaring me. Before 3000 miles it was burning little, between 3700-10000 it was burning a quart every 450 and ford said it was normal (!), between 10-20k it was burning a quart every 400 or so, so this weekend I went to Helen GA and did some hard back road driving and it needed 1.5 quarts over 242 miles (22,575-22,817) and I’ve seen the oil gauge wiggle like never before. I have a feeling it’s going to go soon, perhaps before I make it to the dealer. Hopefully they take me seriously this time. Last time they said less than 500 miles per quart was out of spec but even at 450 they said it was operating normally after doing a consumption test. They can’t claim that anymore.

    Yup, you gonna be upgraded, my friend. Silver lining here! I wonder if a Ford warranty replacement like this with the upgraded engine will increase value more than the fact that it's not the original engine. It certainly could!

    With all I’ve read, this might be the case. If these updated ‘19 engines have less problems, could be worth more!

    Does anyone know if the upgraded oil pump gear is going to be on the GT350 engine or just the GT500? I assume the head gaskets and the heads are model specific.

    I know the block changes and such are the same for all Shelby's.

    Add me to the list :(
    New 2017 (sat at the dealer for 2 years with crazy ADM) with 161 miles on the ODO that I bought about 3 weeks ago.
    Now has 1616 miles. I started to notice the power dropping under acceleration then got a bad metallic knocking from the top end of the engine. It's at the dealer waiting warranty eval. Crossing fingers I get a gen2 voodoo and it's replaced quickly/correctly.

    I wonder how many redline runs on a cold engine were done on your car while sitting at the dealership for two years.

    The 17 I bought summer of 18 had 1510 miles on it and you couldn’t even roll it around the parking lot unless you did a credit check. No revving the engine and there was no test drives allowed.

    I honestly belive maybe we had a bad batch in 17. My car had 4 miles on it. I have a pic. It was roped off inside the main office of the dealership. But yet right at 6k, it went boom. Everyone has read the thread, "Add me to the list nobody wants to be on." Now I have the 19k R engine in and she is running real nice. So who knows ? I believe Ford may have the bugs out now, but wow it seems 17 was the year the bad parts was rolled up to the plant and used.

    Keep us up to date on the oil consumption. I’m taking mine in as soon as I have a short work day.

    So, there are about 41 failures in the poll. There are 1,800 posts and 116k views.

    41/1800 = 2.3%
    41/116000 = .-35%
    and about 20,000 cars built to date, so 41/20000 = .2%

    Feel free to draw your own conclusions as to failure rates.
