Old Trucks vs New trucks

[clean hairy]

So, we know the oldies with 6 cyl engines would run forever so it seemed.
What was the most miles an old timer driver went before their 6 cyl truck went into the shop for engine issues, compared to the newer trucks?

UPS has some of the worst trucks on the road. Transmissions from hell.

And consider how hard and fast they had to be run to make power. Newer engines, gas or diesel, spin at 2/3 the speed of the old engines.

The 4.3 GMs got right around 100k per engine, usually less.

In your extensive experience, how did you come to this conclusion?

The diesels are a huge POS. They are only ordering gas models at my center now.

It is because of the cost of engine replacement and the price of diesel fuel. 1/10th the cost to replace a gas engine.

Waiting for my new engine to be put in my P12

6.0L heavy duty GM Silverado truck engine.

Back in June a utility driver threw two rods. One out each side of the oil pan. Glad I was off that week.

You are 100 percent correct! It has nothing to do with quality... Just how much they can save in the end

New diesel engines have too many federally mandated emissions systems that fail and require constant maintenance. They also have horrible fuel mileage now, due to the emissions systems.

The original 4.3 in my 1990 P1000 went before it hit 50K

I remember when UPS was replacing the 292 straight 6 GMC engines with that 4.3 V-6. The 4.3 had more power but not durable enough. Those old 292's were slower than molasses but would run almost forever.

Had my freightliner (700)since it had 30 miles and now i think im up to 85000 roughly. Fast , been in the shop maybe 10 times for various small things an probably 2 road calls. Its a diesel and compared to the pos hybrid, i wouldnt want one. I think their hybrid was a waste of money only to please the publics environmental eye.

The old 800's could plow snow while 700's will get stuck if there is snow in the forecast.

Much less. 50 to 80k is pretty typical. V8's would have lasted much longer.

A reman VT365 is about $12k and a 6.0 Chevy is about $3k, with about equal life spans and about a third the down time for the Chevy and better performance in general.

No worse than any other. They all get built by the same manufacturers.

I was thinking the replacement costs for the 4.3 (even though we don't use them anymore) was around $1500.

 

[Brownslave688]

Had an old 500 that rolled over a million miles one day I had it. I can only imagine how many miles that thing had put in it.

Reman 4.3s were just under $2k about 5 years ago.
