Idle time greatly affects 6.0 mpg. I don't know if FL is one of the states that gets winter blend fuel but I know here up north the winter fuel also really whacks your mpg. I see a 1.5 to 2 mpg decrease in the winter months and I usually don't let it idle much at all. I plug the truck in to keep from needing warmup time.
Yeh I pretty much hate winter fuel. It doesn't matter how much I baby my truck I can't average sh!t. It sucks. But Florida doesn't get that cold!! I'm in Texas now and am loving this 50-60 degree weather, unlike Omaha where it's in the 30's now.
last winter when I had stock sized tires I got about 15 average with the winter fuel. It was warm the other day up to almost 60° I think but has been mostly down in the low to mid 30's and on a couple of mornings been in the high 20's
I don't have any cold start issues with the Premium Blue 15w40 but I sure did with Rotella. The Premium Blue Extreme 5w40 is even better but it's expensive. I have the inductive heating flash also and that helped a ton but the oil really does make a difference.
Yea thats what I have heard. I did notice the other day that my oil leak appears to be back. Had it back last winter and when it was in the garage they said it was just the o-ring on the oil filter. Well don't seem to be the case since its dry as a bone up top and there is a slight drip coming down the back and off the bottom of the bellhousing on the tranny. Also turbo needs cleaning but I don't think that is giving me any problems other than a lack of boost on the top end. Just cleaned the EGR the other day and it was clogged SOLID, so glad thats all cleaned out.
I would love to switch it up to synthetic as well as put in a bypass filter but both of those may weight till the warmer weather.
Basically if you hear a buzzing from the engine bay after you shut the truck off then your truck doesn't have the inductive heating as part of its strategy. I believe its part of the FICM tuning. Instead with the inductive heating flash you will get the buzzing when you first turn the key to the on position.
I'm down to 13 in 100% city driving with winter fuel.
