Transportation Freedom Act - not political thread

There is a huge difference between a full delete and a partial. The later will cause problems, especially with a vgt turbo. A complete (more pricy) would remove everything off and add aftermarket handholds, turbos, etc.. make her have better fuel economy and longer oil change intervals.

For the price of replacing to a new part egr cooler, actuator, vgt, and scr. You can buy a an entire pre emissions engine. Any thing added to an engine that doesn’t lower the cost bottom line is detrimental to the owner. We have stoped making engines in the best interest of the purchaser of the product but instead of non purchaser activists.- Just my thoughts tonight as I chime in.

 

You are right. Back when Cummins was pushing dieselization 250,000 miles to over haul was norm. Mostly due to low oil quality and oil bath air cleaners. As oil quality got better longitivtiy went up. By the 60’s 350-500,000 was norm. 750,000 by the mid 70’s. By the late 80’s a Million miles was common. Fuel mileage was in the 8’s back in the 1950’s. As hp’s went up mileage went down. 5 and 6’s were high average all thru the 70’s and by late 80’s 8’s were obtainable again in many conditions. These were all mechanical motors too. Slap on the carb crap and we are back in the 1960’s with both again.

 

I used to work the fuel island at TA in Rogers MN back in the day when jbhunt was running cab overs and most of those guys in cab overs were around 7, they got a bonus for good fuel mileage, had to be above 7 for the bonus, that was right before the push to low sulfur fuel. After low sulfur fuel the mileage dropped considerably.

 

I'm not so sure about that one. 7 mpg is average. I think how drivers drive, or treat the equipment moreso affects mpg as opposed to whether it's low sulfur or not

 

It did make a difference with mpg’s. It also made a difference with injection pump and injector wear and longevity. The sulphur lubricated and things wore out and failed less. Less water content in fuels as well. Cetane levels dropped too which meant more fuel burned to make the same energy.

 

Ahhhh I see. I was under the impression that cetane levels were higher in usld. I stand corrected.

 

A lot of the same things happened in the gas engine world to. When the “green” oil thing started and zinc levels were lowered and then all together removed from oil. Camshaft and lifter failures started happening. Roller cams much less but still happen. There again another environmentalist desk jocky feel good solution that screwed millions of engines up.

 

Pretty much. Though ive found fueling in the late morning/ early afternoon tends to have less crowded pumps. Though i try to avoid pee lots and trash accumulators when i can. Those places are always ####holes. Loves is hit and miss and 3rd party places are far better.

Ehhh depends on the deleter too and how its done. I cant go into TOO much detail on what i did to my pete because forum rules.... but there is a middle ground where it can be done for around $6-7K and mine lasted 600k miles after the delete to over 1 million before my motor blew so....there is that.

Reason you see a lot of crap deletes is its illegal so your defacto working with criminals to get it done so you gets what you get and only the ones who get screwed speak up. Most of the ones who get good deletes shut up and say nothing. Doesnt help that a lot of them have zero clue about the motor and do some sketchy crap. Like say to push the motors to 510HP+ on a block set up for 455 or less. It causes a LOT of the issues you see with deletes.

Before it became illegal there were a lot of reputible shops that could would and did do a very good job. Several dealers who could alter the motor to a "military" style spec as well. And deletes were super common and most who had those rigs say 600-800K easy without issues.

 

There is a reason the military and much of the rest of the world runs deleted. The engines will do their job. Meanwhile Canadian, US, and Western Europe markets have paid an economic penalty for wishing diesels will work correctly if smogged down. Truth is it doesn’t work. If it did, the rest of the world would buy into the sham.

 

This was 7mpg in cab overs, not aero plastic trucks.
