When do you know it’s time to tune your truck?

No semitones for Bs and Es, my friend.

 

Drop in fuel mileage is a good indicator.

Could be a sign that the DPF needs cleaned.

Go to Cummins website and look at maintenance intervals. Oil and filter changes I wouldn’t go over 25k miles and air filter at 100k under normal highway conditions. The other things Cummins recommends are pretty accurate though.

 

There is no such thing as a B# or an Fb, but there is certainly a Bb / A# as well as an Eb / D#.

 

Sorry bud, no semitones for Bs and Es. You can make the argument that moving up (or down) the fretboard is technically a sharp (or flat) but music theory is not my major. I just play!

 

While I have no experience playing stringed instruments (thus I cannot address the fretboard argument) I assure you I have played countless Bbs and Ebs on piano and brass instruments.

If you look at a piano keyboard, you will find that there is no black key between B & C or between E & F. But there is a black key between A & B, and between D & E.

 

I'm surprised that nobody has brought up a story about an old Detroit getting tuned up, then when started the rpm taking off till it blew up.
Nothing like the sound of a runaway jimmy and watching people run for cover before it comes apart and starts throwing heavy chunks of steel through the shop walls lol.

The good old days.

Or who remembers split rims, and beading tires on them with a can of ether. But I digress, back to 6 strings and bass guitars.

 

Missing on acceleration or a backfire on deceleration. Check the plugs.
May just need a cleaning and regap...

 

back in the olden days we had to change out the spark plugs every 20,000 miles and replace the points and condenser at the same time. so this could be like 2 times a year way back then. or, spring time then fall time.....

now a days, plugs can go as much as 100,000 miles, but always make sure the tech (or you) put some "anti-seize" on the plug threads so as to not let the plugs seize up into the threads of the head. that can be costly.

always replace the fuel filters, air filters as well. also check the condition and freeze protection of your anti-freeze. and if you have plain water in the washer fluid jug? replace that now with washer anti-freeze.

 

Yes, no sharps, or flats for B and E and the piano is indeed a stringed instrument.

 

If you run over a C sharp, you may B flat.
