Is that right? Halfway thru second tank, avg just under 11 mpg (AC on max all the time). That's a long way from the 16 listed on the sticker. Truck now has over 500 miles on it, about to swap out the oil. Does running the AC all the time effect the MPG that much?

:) I get better than that with my 6.0 and 4.10 gears :dunno:

 

Are you always on the hammer? You shouldn't have any trouble getting at least 15-16mpg average.

Reset it and drive normal (not lead footed)...it will average out over time. Especially with highway driving. Mine stays at about 17.9 all the time....5.3L

Did you reset it before taking it home from the dealer? If not, that truck could have seen a lot of idling, test drives, moving around the dealer lot, etc. Lots of really short trips will read low mileage.

Give it some time. Your gas mileage will go up as you start getting into the 3,000-5,000 range.

 

500-1000 miles is still breaking things in and the computer takes some time to dial everything in.

That's probably why the average MPG is so low. I have seen trucks with 6-7 MPG average accumulated during test drives and moving it around the dealer's lot.

Immediately after each fill up, you have to reset the 'avg fuel economy mpg', and 'gallons used' to zero. You can't reset

the 'fuel range' numbers. They are calcuated by the gallons u put in and previous avg mpg to give u the distance u can

go with the amount of gas in the tank.

You can optionally reset the trip meter to zero, if you want at this time.

After each fillup I reset the trip meter, avg mpg, and gallons used.

Rember that mpg is most affected immediately after each fillup and DIC reset. The more miles you put on a tank

the less sensitive it is.

Some trucks have an instantaneous mpg reading instead of the avg mpg. I don't remember which ones, maybe the LTZ's.

In any case, avg or inst. the DIC should tell you.

      OCI, not when but why?

      By Chuck FB · Posted

      If all oil manufacturers had to meet a higher standard for not just the initial filtering of the oil but that they had to improve on their formulation so that the oil cleaned the engine such as the Valvoline R&P or the new Mobil product ( assuming it works similar of course ), and the oil was changed on an interval based on good UOA data, there shouldn't be any gremlins running around like miniture rats on top of your heads to be washed down into the oil pan below 😁

      A while back on another thread there were comments and thoughts on air filters and I know that can tend to be a bit of a hot topic because of outfits that have a vested interest in selling aftermarket air boxes fitted with the gauze type of oiled elements touting the lower air restriction. However and unfortunately I don't know where I have seen the test results in the past about the amount of dirt through a test procedure that these style of filters do pass more dirt through than a properly designed ( not some cheap Chinese knock off ) paper/synesthetic media filter can do. Lake Speed had a conversation on that topic with one of the employees at Donaldson and there seemed to be a consensus of these oiled filters falling short in the absolute percentage of dirt holdback.    Which all ties back into how good the air filter is on the engine at keeping dirt out as that is going to reflect as a contaminant introduced into the oil as well as cylinder wear even if some of that dirt does find its way out of the exhaust rather then the crank case. Put another way that one can throw the kitchen sink at filtering the oil and using a bypass system which I fully expect will do nothing but good for the oils contamination but if the air filter system isn't doing its job then its preventing the engine from reaching the best wear/lasting case scenario instead.    Now perhaps this topic is or isn't for this particular thread but Grumpy Bear or anyone else for that matter, do you have access to some scientific trust worthy testing on engine air filter types to get some proper comparison data to post up.

      WOW, something we agreed on. I only bought at sticker twice. A 94 impala ss and an Acura intagra type r. Made money on the first. Still have the second.

      I prefer new, but not without a deal. Historically I've bought severely aged new inventory, leftover model year, unpopular configuration kind of stuff that sits around on dealer lots until they just want it gone. $10k off MSRP kind of stuff on a mid-priced truck. That really, really helps knock down that first year depreciation. It also requires being somewhat flexible on colors and options. I wouldn't buy a 4 cylinder if I was looking for an 8 cylinder, but if I got blue paint instead of black, or a great deal was lacking a minor option, I'm willing to overlook those things for savings.   Used <> used. Condition and history are everything. If I'm buying used I'm looking for cream of the crop. The truck from the guy who religiously pampers it, and then decides a year later he wants newer and nicer. NOT the ex-rental vehicle, or the crew cab traded in by the family with 7 kids who like to throw food, and the oil only got changed when there was time long after the oil life monitor started alerting.
