Waiting on my GWE. Not sure what grade fuel is required for these beasts! What grade is recommended from dodge? What do you guys use?
Is it also true that it comes with ,and requires synthetic oil?
Grade fuel required: 91 octane
Grade fuel recommended: 91 octane
What I used: 93 octane (the place I use no has no 91)
Type oil vehicle comes with: API Certified SAE 5W-40 full synthetic engine oil, API Certified. (Probably Pennzoil)
I'd always use synthetic. 0W - 30 to 10W - 50 is fine.
I'm almost certain the window visor SRT label recommends 93. I'll check tomorrow to be sure.
Ordered a 2011 SRT8 (non-IE) on November 9, 2010 in Brilliant Black Crystal Pearlcoat, 5 speed auto and fulllllyy loaded! Her name is Stella
Current Mods: Speedlogix Splash Guards, Speedlogix Catch Can, Fastman 84MM Throttle Body
Planned mods: Mopar CAI, Strut Tower Brace, Kicker Double Subwoofer
The SRT8 technician at the local Dodge dealer says the 392 will pull so much timing on 87 octane that it will be down at least 30 HP compared to 93 octane. The engine is rated for HP/TQ on 91 octane and will make even more power on 93 octane.
