I drive 70 miles/day & usually fill up every Monday morning with 89. A full take in my RT (no mods other than exhaust, it's a 2011) depending on traffic in LA & OC I can pull into the garage on a Friday evening with 30 miles left in the tank. Add weekend driving and I'm filling up at least 5 times/month. Getting anywhere from 21 to 23 MPG which I think is pretty good for a V8 and crawling home in traffic for 1-1/2 hours each day.
every weekend (saturday maybe even friday) but even though its a V6 i can fill up twice a week... Drive 60-80km a day, half of that being traffic. half being highway. and 75% of the time driving like a stole it... So 4-6 times a month.
Same here! No grinding daily commutes are a Challenger owner's best friend. I'm slightly over twice a month, though...but those are half-tank visits, so I guess it works out similar to your own setup.
Wow! How are you getting 25-30 MPG in an SRT8? I understand it's all highway but my RT on 95% highway driving per week is pretty far from what you average (21-23).
Hmmmm, my last fill-up was 10 days ago and I'm down to about 1/8 tank, a good chunk of that was from driving to/from a car show in Costa Mesa last weekend.
So, under normal conditions I'd say at this point it gets filled up once a month, maybe twice if I take it on a long drive.
