Thousands upon thousands of Semi/Tractor/Diesel rigs would tell you otherwise.
Yes, joking… diesel, turbo, etc., apples and watermelons for comparison. Joking.
I didn’t trust turbo cars of the 80s, 90s, etc.
They’re coming around to me… and tech has changed.
I’m closer to acceptance now than I was, say…5 years ago.
Tech has changed...but not. The problem, and it's not just the vehicle manufacturers fault, it's the EPA. Look at our NA trucks. 203 degree thermostat, active grill shutters, and guys are seeing temps near 230 in the summer. It's emissions + forced induction=big problems. The majority of mechanical issues with the 5.7 and even the ZF trans is because of the EPA. We should have 5w-30 in our trucks. Miraculously it disappears from the manuals because the EPA got on them because "heavier oil decreases mileage." So we are left with "manufacturer recommended 0w-20 or 5w-20." The rumor of why the ZF trans are "fill for life" is because the EPA doesn't want to deal with 7 qts of ATF having to be recycled. Meanwhile, BMW specs a 60k pan/filter/fluid change
for the same exact trans.
So what do we think is really going to happen with these new I-6 turbo motors? We all know what happens to turbos and top-ends when oil gets really thin and things get toasty.
Comparing the old 80's turbo cars to these new motors is basically like you joked about comparing a turbo diesels to diesel gas. Those 80's-90's T-cars would not even get passed phase 1 of EPA approval. That's why they lasted so long. Look at the old Supras. They got put into the pasture due to emissions.
I have 3 turbo diesel motors in my family's household, btw. A 2006 pre-emissions 2500 with a Cummins that's an absolute clock with 275k on the odo. Then 2 marine diesels which are the biggest pieces of $55,000 garbage a human could ever imagine. Why? Because they just missed the emissions cutoff and went to the newer CAT ACERT design. Oh and what does ACERT stand for? Advanced Combustion Emissions Reduction Technology.
The EPA does not care that we are getting less than 100k out of drivetrains anymore. It's tough to put the blame solely on all these manufacturers. We can go down the rabbit hole into things like tax-credits, subsidies, and things like that for EPA compliance but that's above my pay grade.
Bottom line is if anyone believes an I-6 turbo in a 5000 lb truck in a day where the EPA is designing the motors will have any sort of real longevity (or even be problem free)....I have a bridge I'd be willing to let go cheap. It's in Brooklyn.
