Mobil 1 0W-40 is the European blend. Not sure if they are making a 5W-50 with that same additive package, but if so, it will be fine. Check bobistheoilguy.com for more accurate info on the additives.
Yes, but unnecessary if you’re not tracking the car. Truth is, 0W-40 is probably overkill on the viscosity also, but I’m 3 months shy of using Mobil 1 FS 0W-40 for 9 years and 38k miles. Works great for me.
Yep, going on 9 years and 38k miles. Zero oil consumption or oil pressure issues. Since I put a little over 4K miles on the car in a year, I just change it annually.

$550, which includes USPS Priority shipping and PayPal fees.

I always thought a 4.30 gear would be a sweet spot, but at that ratio, you're just a couple of...
Installed my ATX-20HD this afternoon, did the BMS reset in Forscan, and currently waiting for the 8 hour relearn. Can’t drive the car anyway since it’s been raining for a month it seems.
Reviving this thread to note that I did resolve the shifting issues by changing the reported gear ratio in the BCM and the PCM (BCM only didn't fix it), which solved the shifting flare issue altogether. This does require a custom tune, however (I have HP Tuners and am long since out of...
Today, I finally finished a project that has been nearly seven years in the making. I ordered my GT350 in September 2015, and before I even drove the car, one of the first mods I considered was to match the 8250 redline with a 4.56 gear. Since no one made any aftermarket gears for the Super...
