Go Big - IMO getting 16.8 - 17 mpg with these trucks requires really good gasoline, ambient temp around 90deg F, and lots of luck. I use Castrol 5/20 Titanium Syn "oil" and run 89 octane every 10 fillups just to see if that helps. 89 oct does seem to help about 0.3-0.5mpg when towing 10K lb 5er, but economically it's not beneficial. (Summer blend gas)

I agree the design engineers need to drive and use these trucks prior to general release, but then the price tag would go up. Prior to this truck I was using an '03 Bowtie Dmax w/Allison Trans. Wonderful truck when everything worked - a real pain when injectors decided to crash since they were under cover.

 

I haven't change my first oil yet and when I do thought of going to a Full Syn..Do you feel your Castrol full syn helps in any way to quiet down the ticks of this engine?? Did you notice if your truck engine ran smoother with full syn vs Motorcraft semi syn?

 

Since most syn-blend oils are 10% syn or less, I personally see very little benefits to syn-blend vs the cost. Unaffected flowability is maintained for only 3-5 deg F vs pure dino and syn-blend only slightly improves the viscosity life expectancy vs pure dino; yet at the same time commands a premium price. For a very few dollars more full syn oil can be used that improves flowability stds down to -40 deg F and increases visc life expectancy 50%. Doing the math tells me to skip syn-blend.

Will full syn oil quiet the noises? - I seriously doubt it and have not noticed that benefit in 3 vehicles I have run full syn in whether gas or diesel. Keep in mind my last daily driver for 10 yrs was a Dmax Diesel, so almost any gasser is more quiet to me. The main constant noise in the cab for mine is the exhaust system. If the "sewing machine tick" gets much louder than it currently seems to be, I'll start having flash-backs to the Isuzu LB7 Dmax injector nightmare.

 

I currently own a 2009 hemi ram and a 2011 6.2 limited and have to be honest the hemi is a dog compared to the 6.2 both are tuned so that's not the difference so you may have a problem with your truck .

 

Well, I put close to 250 miles on it this weekend through a mix of freeway/mountain passes/country roads and it's running noticeably better. The fuel economy increased up to 12.8mpg. I reset it just to be sure it wasn't because of higher speeds and it's already at the same level.

 

Great!! See give it alittle time for it to break in and you should see if go up..I got 1500 on mine and lifetime is 12.9..90% city..I am expecting 12-14 city and 15-17 highway once it gets broken in and summer fuels kick in..Not far off my 13F150 and I can live with that..

 

Put a 5 star tune on it and you will be loving that 6.2 takes all the sluggishness out of that motor . Made a quite a bit difference in my truck .

 

I've been looking at them, think I'll get one. Need to Linex the bed, too.

 

I agree.
87 Performance/Tow is great. Ran the 91 Performance/Tow then switched to 87 and didn't really notice a difference except in the wallet.

 

I'm running 93 performance tune and it costing my wallet also in buying tires lol.

 

I put under rail led light in the bed of mind same time I did the linex along with a lazer lite tonneu cover which look really cool at nite
