No, 300,000 miles on a well-maintained diesel isn't inherently bad; many last much longer (up to 500k or even a million miles), but it signifies high mileage where significant, costly repairs to components like injectors, transmissions, or suspension become likely, requiring thorough inspection and service records to assess dependability, according to Capital One and Quora users. The key is condition and maintenance, not just the number, as wear items will need attention.Is 300,000 miles on a diesel bad?

Neither mileage nor age is definitively more important; both matter, but maintenance history and overall condition are the true deciding factors, as a well-kept older car can be better than a neglected newer one, while age brings rubber part decay and newer safety tech. A good rule of thumb is to look for cars with average mileage (around 12k-15k miles/year) that are 2-5 years old, but always prioritize a thorough inspection and service records.What percent of cars last 300k miles?

Diesel engines are often acceptable under 200,000 miles, provided you pay close attention to the truck's overall condition. Most experts advise against buying a used truck with over 100,000 miles, as major repairs and the replacement of significant components may become a regular occurrence.How long will a Duramax diesel last?
A Duramax engine can last for 300,000 to over 500,000 miles, with many owners reporting 300k+ miles and some exceeding 1 million miles, especially with diligent maintenance like timely fluid changes, quality filters, and addressing common issues like those in the emissions system. While the average expectation is around 200,000 miles, exceptional longevity is common for well-cared-for Duramax engines.Which diesel truck engine lasts the longest?
Which diesel engine lasts the longest? Cummins engines generally have the longest lifespan due to their simple inline-six design, strong internals, and excellent parts availability.

Is it better to own a diesel or gas truck?
Diesel trucks offer superior torque for heavy towing, better fuel economy (MPG), and longer engine life, ideal for work, but have higher purchase/maintenance costs and complex emissions systems; gas trucks are cheaper to buy/fix, provide quicker acceleration, and are simpler for daily driving, making them better for lighter use where extreme power isn't needed, though they're less efficient and durable for heavy-duty tasks.What is the 20/3/8 rule for buying a car?
The 20/3/8 rule is a car-buying guideline from The Money Guy Show, suggesting you put 20% down, finance for no more than 3 years, and keep total monthly car expenses (payment + insurance + gas) to under 8% of your gross income to maintain financial health. This strategy helps you avoid overspending, depreciation, and getting "upside-down" on your loan, ensuring your vehicle supports your budget rather than burdens it.What happens if mileage is too high?
Too much mileage means increased wear on major parts (engine, transmission, suspension, brakes), leading to higher chances of costly repairs, lower resale value, and potential breakdowns, though consistent maintenance can significantly extend a car's life beyond typical expectations. Expect more frequent fluid changes, tire rotations, and eventual major component replacements, with digital odometers often resetting to zero or getting stuck at 999,999 miles.At what mileage does a car lose value?
Every 20,000 miles driven can lower a car's value by about 20%. Trucks and SUVs, like the Chevy Silverado 1500, often hold their value better due to their durability.What car is the poor man's Ferrari?
The most common "poor man's Ferrari" is the Toyota MR2 (SW20 generation), nicknamed the "baby Ferrari" for its mid-engine layout, sleek styling reminiscent of Ferraris like the 308/348, and accessible price.

Specific model years matter, but generally, older, simpler designs from Toyota (Tacoma, Tundra) and Honda (Ridgeline) often have fewer surprises than complex new tech in some competitors.What is the most unreliable diesel truck?
The most notoriously unreliable diesel trucks often cited by owners and shops are the Ford 6.4L Power Stroke (known for catastrophic failures and transmission issues) and the LML Duramax (2011-2016) (frequent DPF/EGR/fuel system problems), with the Ford 6.0L Power Stroke also infamous but fixable with upgrades. Other mentions include early 6.7L Power Strokes (2011-2014) and some Dodge/Ram EcoDiesels.Is it a felony to delete a diesel?
Yes, deleting emissions controls on a diesel truck (like a DPF or EGR) is federally illegal in the U.S. under the Clean Air Act, carrying risks of significant fines (thousands per violation) and even prison time for individuals and businesses, though federal enforcement often targets companies, not just individual owners. While there's ongoing debate and some confusion due to potential rule changes or rumors, current law prohibits these modifications, making it a serious violation, not just a minor infraction, especially for businesses selling or installing deletion parts.Should you let a diesel warm up?
Yes, you should let a modern diesel warm up briefly (30 seconds to 5 minutes depending on temperature) to circulate oil, but gentle driving is better than prolonged idling; letting it idle too long causes wear and soot buildup, while gentle driving under light load warms it faster and more efficiently. For very cold conditions, use a block heater if possible, and always drive gently with low RPMs until the temperature gauge is normal to protect the turbo and engine components, notes this YouTube video and this Facebook post.
