Hello Everyone, For those of you equipped with Active Fuel Management, I'd like to know what highway MPG you all are getting. Earlier this year I purchased an 08 Silverado WT, 4.3L v6 for commuting purposes. I thought getting the 4.3L v6 would give me the best MPG (as far as full sized trucks are concerned). I'm beginning to wonder if I should have put out more money to get a bigger engine with the Active Fuel Management especially since most of the driving I do is freeway driving. Look forward to hearing from you all! Thanks!
