How long will a 2002 ford 250 diesel engine last?
JEREMY A asked:
My dad has a 2002 ford f250 diesel at 100,000 miles and I can buy it for $13,000. Currently I drive a 2002 toyota tacoma at 50,000 miles and owe $6000 but can get $14,000 for it if I sell it so financially it will won’t cost me anything different. I am trying to figure which is the better deal.

The diesel engine itself is one of the best running engines ever invented. You need to look at the other things that can go wrong, transmissions, struts, etc. Is it highway driving or towing? Was the truck well maintained?
I agree with BeckyH, it is highly likely that the diesel engine will out last the rest of the vehicle as long as it is well maintained. The 250 diesels are well made engines and for $13K you’re getting a very good deal.
Take care of that diesel, and it will serve you for at least 500,000 miles. 1,000,000 miles is possible.
Change the oil RELIGIOUSLY! Diesels are also very sensitive to clean fuel and air, so change those filters BY THE BOOK and the wheels will fall off before the engine heads south.
My last 03 model had 765321 miles when I let it go and heres why .
Once per month: Check all fluid levels under the hood. Automatic transmissions and most power steering fluids need to be checked hot with the engine running,
Every 3000-6000 miles: Lubricate, Oil and Filter. Harsh conditions require more frequent service than highway miles.
Every 5000 miles: Tire rotation. Front tires usually wear faster than rears because they get some side slip from cornering and have more up and down movement than the rears.
Once a year: Have all the lights, the windshield wipers, battery and cables, charging and starting systems, belts and hoses checked and serviced as needed
My daughter has the same truck. The upkeep on it is high, oil filter cost 3 to 4 times what your car filter does. Same for fuel and air filter. Plus this demon uses 3 gallons of oil. Your car will also get twice the fuel millage. Plus if anything breaks, ouch!! This engine will last for 500,000 or more miles, if taken care of at a very high cost. My advice is to keep your car. If you take care of it, you should get 200,000 miles or more out of it. My son has one of these trucks also. His has a standard transmission. To have 6th gear called overdrive gear replaced and new clutch cost him $1800.00. On my daughters truck the water pump went out and they wonted $600.00 to replace it, I did it for her at a cost of $250.00. Do you get the point i;m trying to explain to you about diesels? They cost an arm and leg to have one.
It really depends on what you want to use the truck for. If you plan to haul and/or tow very much, go with the truck. If you are going to just use it for transportation, keep the car. The others are right about the maintenance, keep it well maintained, and it will serve you well for many years. I have had at least a dozen fors diesels, and they all have been good. I currently have a ‘97 with 360,000 miles, and still use it hard every day. But it is regularly serviced.
for as long as you have it great truck
Change engine oil and filter often, air filter, and fuel filter.
For some reason people who drive diesel think that the engine will last forever, but it doesn’t.
Buy the truck
I have a 99 F350 and it has 366,000 on it, doesn’t use oil or water. Yes the filters are a little higher, but you cant beat the truck.
