With a 04 TL can the engine run fine on mid-grade, or a 50/50 mix of premium and midgrade? Because I want to drive it often when I have time to get better at driving stick, and paying $0.60 per gallon more on premium over regular is not THAT big of a deal, but would be good to know.

 

Engine will seize if you don't.

 

Midgrade is usually a 50/50 mix of premium and regular. There's literally a ton of threads about which gas can I use on the site.
