Car is thirsty ALL the time. Not sure if it's the Cobb tune, the Kline Inconel Exhaust or just 911's but I'm getting 11-16 mpg on average. The 9 mpg is from Friday night...Drove 8.4 miles, half tank gone, no joke.
I've spent a lot of time in the PNW, especially Seattle/Bellevue/Sammamish/Issaquah, love that old Gilman area Your .2 optioned with PCCB?? Car looks great!!
I've aways figured any of the big name companies like Shell/Chevron are the way to go. You guys don't think the discount places like Valero might have cheaper detergent additives that might let DFI engines build up more deposits over time?
