Secrets to fuel mileage. (Page 4/5)

Some thing else that seems to work for me is, never trying to accelerate while going up hill. Just maintain the speed you were at or, keep the rpms within the power band.. In my current one ton, that sweet spot seems to be in the 1500 rpm range. Always try speeding up when using gravity to help. It's a small thing but, if you work at it, it does seem to pay dividends.

Use non ethanol gasoline to get better mpgs.
But it may not save costs as its not subsidized.

That might not work out well for blackrams

Knowing just what to ask from an engine, and how to ask nicely can make all the difference in the world. Kind of like some women.

Back when trucks still had pyrometers and manifold pressure gauges (before computer controlled engines), I drove an E6-350R Puppy Dog that would blow away an NTC-400 on a hill and get 6.8 mpg while the Cummins was lucky to get 5.5.

I could keep the exhaust around 910o and get 23 lbs of boost on a cool day (air-to-air CAC). The NTC was cooking at 1250o and making about 14-15 lbs of boost.

All that extra fuel went out the stacks as heat and smoke. Some guys used to think that smoke equaled power.

Hell, I even talk nice and say sweet things to my Cummins if it'll get me a half mile per gallon better fuel mileage. Don't tell my wife that though.
But, I do realize that not everyone has the time or patience to plan ahead and try to save a few bucks on fuel. I suspect more folks will start doing that as the cost of fuel continues to rise. I want to take a moment to thank Ole Joe for killing that pipe line. I know it's not the only reason costs are rising but, doing that sent a message to everyone.
Just about everything moves by truck, if it costs more to get that product or produce to it's destination, it's going to cost the end user/consumer more.
Biden supporters, don't say you weren't warned.

2.5: My Cummins burns diesel.
But, you may be correct in gas burning engines. I suspect anything with corn alcohol in it is less efficient or so I'm told.

Did I say Corn Squeez'ns? Didn't think so.

But you're correct, I try to not partake of alcoholic spirits. But, there are always caveats ya know.

hmm I remember a craze of burning french fry oil "biodiesel"

Might not be much cheaper though either.

I had a friend with a "source" for that cooking oil. That's all he ran in his older diesel. He had barrels of it but, it has to be filtered several times to ensure it's clean enough to go through injectors. He spent a lot of money on a filtration system and that system took of a lot of space in his shop. Not suggesting it isn't worth it but, you gotta have a source and I'm not sure it's worth it for all the time he spent messing with the system. But, as the price of fuel goes up, that craze will come back.

Willie Nelson is everybody's friend.

If you read the article you will see that Willie had one of his biodiesel plants in Carl's Corner, Texas. I have been to Carl's Corner, every time I passed through (on IH 35 just south of Dallas). He has a large truck stop there which is almost a Willie Nelson museum.

Did he find cats licking his exhaust pipe?
