I wish I was only paying a little more for non-ethanol gas. Its a buck fifty more per gallon here. But I still buy it, the truck sits for too long between drives to not use it. But I didn’t switch to a big block for the mpg anyway.

Of course I'm concerned about gas mileage in my truck, always have been... as I continue to drive it same as always only costing more

Okay done with the hijacking. I do care about MPG. I record the mileage and fuel purchased at every fill up. This allows me to notice if something is changing with the engine or possibly the drivetrain over time.
If I drop from 12 to 10 MPG over a month something has changed on the truck and it is time to take a look at things.
The last time it happened was in July when it was caused by my rear axle getting bent in a fender bender I was in. There were other clues that helped me pin point where the problem was but the first clue was the fuel usage.

Thanks HO455 - I finally posted a greeting in the Welcome Area.

I may be when I put an overdrive between the tranny and the 4:56 rear, in my C30, but until then, naaaaaa. ( and then it’ll just be curiosity) I‘m just more concerned about lowering the rpm’s than I am increasing the gas mileage.

Would be my main concern also for my 68 . 4:56 250 4spd there's only so much you can improve driving a brick .

Only concerned with MPG as a function of range. With every improvement in reliability, I'm looking to drive farther without having to stop for gas every 3 hours.

Either that or just get a bigger tank under the bed.

Exactly how I feel. And I assume a 2021 Duramax 3500 would be more than $600 per month....?

Probably closer to double that.

Easily, double that. My 2015 Ram 3500 is over a $1000 for 4 years, not to mention almost $400 a year to keep plates on it.

Exactly! I get 7 MPG towing the travel trailer. Each saddle tank gets me about 100 miles, with a little reserve. Of course, that's almost two hours of driving with each tank, so that's a good time to stop and stretch and let the dog out for a break, too.

I do care about gas mileage but I'm a tight wad. I try to get the most out of everything. I have a 292 and OD trans with 3.73 gears and I get about 18. My goal is 20 but it doesn't look like I can get there from here.

Non ethonal high test is maybe 10 cents higher than high test with ethonal. No regular 87 octane without ethonal. But I wouldn't use regular anyways

**Already Gone** · 10-11-2021, 03:07 PM

I have owned my presenttruck since 2014 coming up to 7 years and average about 1000 miles a year. I dont worry about gas mileage but the rip off gas prices bother me.

Two of our neighbors just bought Tesla's. One the SUV and the other is an "S" model. Both are damned nice cars.

If my wife wasn't so dammed mean, and I had Jay Leno's $$$, I would look into Electrifying a C10. But, it ain't worth dying over...

Turn the entire engine bay into a refrigerated cooler.

Some is due to fuel distribution delays. As in, a driver shortfall. A BIG issue in the UK where they have issued a National Emergency to deploy military drivers.

Its not developed into a fuel shortage point here now but, is creating part of our current problems. Hell, a driver shortage was a problem here before the pandemic.

Sorry...Duplicate post.

burnin oil · 10-11-2021, 09:29 PM

At 7 MPG I worry alot. That said a 30 minute drive puts a 12 hour grin on my face. By my calculations that is way cheaper than therapy. Now if the cost of high test would go back down I could have 45 minute sessions instead! Seriously I don't care about fuel cost and enjoy my truck and the only thing is I enjoyed it more a year ago. My income hasn't changed as costs rise. I would rather wear out the motor than let it rust from fuel costs. I filled up the other day and quit looking after $75 and just filled the tank with high test. Most of my vehicles hold 30+ gallons.

**Canuckvetter** · 10-16-2021, 10:21 PM

I did check the 67 once and it got 20 mpg on the highway with a 3.07:1. Now when it gets close to empty I just put more in. The 72 corvette gets 2hrs to 20gal if I’m easy on it. Good thing is I only go through 2 tanks of gas a year.

Saw a post with someone doing electric and putting the battery pack under the hood. Estimated 60 mile range. You would have to fill the bed with batteries to get a decent range. Even the new Ford Lightning has limited mileage when it has an actual load. Something that is not marketed.

KW5413 · 10-17-2021, 09:48 AM

If I were to electrify a C 10 it wouldn't be to haul loads...LOL. At that point it would be a rest-o-mod on steroids.

It would be a custom frame with a Tesla style lithium battery positioned between the frame rails with (4) independent drive motors. Air ride suspension, etc.

A $ 250,000 truck build worth around $ 150,000
