Replace all 8 glow plugs labour and tie up any loose ends and you won't get much back from 2.5k. I'm not sure what kind of truck you have, but I'm quite sure it wouldn't serve my purpose.
Also keep in mind that injectors and other items I listed will be well over $2.5k so your argument is moot.
I have a f450 that's built, I also have had lots of regular diesels that have been nothing but preventative maintence. They have still been well over $10k the first year between upgrading the hpop, egr, dpf delete tuner and exhaust and regular upkeep. Great trucks and once it was sorted it was great but small breakdowns would still wipe out any fuel saving. I usually buy one truck a year so keeping tabs might not be the easiest thing for you.
If you do your oil changes at 20k then I'm guessing we have different definitions of maintence or very different ideas of what a truck is.
Not sure where you are seeing a bias.
No shop that I would trust my trucks with will do a Dino oil change for less than $150, I use synthetic at $200. Modern diesels have ridiculous fuel contamination issues. I would suggest looking into it.
Take a whif of what your oil smells like at 20k and let me know if you still think that's somewhere you want to save money.
$15k.. Have an injector stick open at 20,000 psi and I want to see what your bill is. Mine took out a 6 month old $45k engine build.
I do know a bit about diesel trucks I run them 90k a year and have been for quite a while.
I was like you the first couple of years and believed they were the greatest thing since sliced bread.. After sitting down and doing the math its really not the case.
the old diesels 7.3 and 12v were awesome but dont fool youself into thinking the modern diesels are the same. I know if a ton of cummins 6.7s that have had headgaskets swapped, etc.
Power-strokes 6.0 egr, HPOP issues. 6.4 broken pistons are the norm.
duramax - 2000-2005 were nightmares for injectors. I knew a guy that had pit on 5 sets by the time he was at 200k and he wasn't the only one. Don't know about current duramax trucks.
Guys that have been running much larger fleets than me for way longer than me are swapping over to gas, there is a reason behind it. Watching a gas tow truck tow away my diesel for the third time gave me something to ponder, lol.
No no, not biased at all....
Glow plugs are $2.5K!?!
I mean, if you at least threw up some reasonable prices i could maybe agree with you, but with your exaggerated pricing, you lost any and all credibility.
Let me tell you what my costs for running a diesel are.
$95 oil changes that are schedules at 20K! I change it at 17K just to be on the safe side
Super duper expensive glow plugs for a super duper rare Mercedes engine? $22 each.
Gee, running diesels is so much more expensive and yet everyone and their mother is switching to Sprinter Vans with the 2.7 and 3.0 diesels as they are that much more economical to run than Gasser vans.
Dont be an idiot with a diesel and it will last you a lot longer than a gasser.
How much of your $15K cost has been go fast goodies and or things you broke due to pushing the engine limit? On one end you admit to 1200hp diesel and on the other end you ***** about reliability?
