2026 Mustang GT Convertible
Love it! I traded my 2017 Carrera for this Mustang, there was change, because I wanted, needed, required a convertible! Having once owned a Lava Red 2012 Mustang Convertible, V6 manual, I wanted another one with a V8 manual. And I have it and I love it more than the 911, way more fun.
I was happy to be accepted into this forum, thank you, after getting caught up in a discussion on the proper oil level for the car. A few weeks ago, with 5000 or so km, I called my dealer asking why the oil level was around the first hole on the dispstick. Normal, new engine bla bla bla. Bring it in and we will change the oil while we check other things. Their receipt shows 9 liters. All good.
I left without checking until 1000 km, mostly highway, later only to find the level at hole #1.
Upset.
No one was answering in the service dept and I left a detailed message on their machine which promised a quick reply. I am still waiting after several days.
There is an adventure here, how much oil has to go in? 9 liters or 9.5? 10 quarts…US or Imperial? Not the same! Which one converts to 9.5 liters which fora consensus accepts as the proper quantity (US quart).
I just gave up with the calculations and conversions after consulting Ford Canada, US, UK and France sites. No wonder international discussions go haywire! So I bought a liter of synthethic Castrol as per the required recipe and added less than half of it. I have yet to check where it's at but at least I have a poper baseline for the next few hundred KM.
Love it

You have to remember oil changes volume as it gets hot or cold.

Check it after it reaches operating temp and get back to us.

If you ever have owned a Harley Davidson (if you own a Ford and a Harley you really need to seek help) you'll see the dipstick has different markings for hot and cold, and a HD has a lut less oil in it than our 5.0

Most manufacturers consider burning a quart every 1500 miles "normal", I dont
