I am looking to buy a 2000 to 2010 Full Size Pick-Up and would like to know which engine is the best 6 cyl or V-8 engine that has the best track record of the less amount of trouble and repairs?

If you could tell me which engine is the best performance in Ford F-150?

Which engine will get 300,000 miles and is solid as a rock trouble free.

Do you feel that there are very solid Full Size Pick-Up out there in these years?

I keep all my vesicles in top running conduction.

 

Id say the 4.1 i6

 

I've never heard of a 4.1L I6, and one certainly wasn't installed in an F150.

It's tough to isolate the engine from the system as a whole, and there are pros and cons to each. I'd argue the later 2v 5.4L engines found in the '01-'03 F150s are probably the most reliable and best performing of the group. The 2v 4.6L engines are also quite reliable, but they don't have the power of the larger 5.4L models.

The 3v engines seem to have lots of problems with their timing gear, but they are more efficient and make great power. Later models, in the '09 and '10 F150s, got the much-improved 6R80 transmission that's both more reliable and better performing than the 4R70 or 4R75. The '04-10 trucks are also much more refined and better handling than the '97-'03 models that the 2V 5.4L could be found on.

I'd suggest focusing on the truck as a whole rather than just the engine.

 

I agree with TOM on the motor in the 01- 03 being better than the 5.4 in the 04-09.... if you were past 2010, that might be different.

Gs mileage is a factor also, would you say the 5.4 would give you better gas mileage than the 4.6?

 

Under most circumstances the 4.6L would be more efficient. The exception would be if heavily loaded and the 4.6L has to operate in a lower gear than the 5.4L.

The smaller engine would be operating under less manifold vacuum for a given driving condition which reduces pumping losses. Shorter stroke also means less frictional losses.

 

The 4.2 V6 in my 2006 has been relatively trouble free, I did replace the water pump at about 190,000.

It seems to have plenty of power for driving, it is noticeably weak when hauling a big load. It really reminds me of driving an older model with a 302 in it.

aw crap i meant the 4.2l v6

 

alot of the fleet trucks I see are running 4.6's. I have a 4.6 with 155k and its been a sweetheart. it won't win races but i'm not racing in this bloody thing...it gets to 70-75 with no issues...still gives me 18-18.5 mpg on long trips. it will haul my lumber when I am working on a project or whatever. Ford's version of the 22R engine IMO.

 

I have not replied in a while and after reading the replies my best bet is the 4.6 because I am not really hauling things every day and I don't need allot of power to do what I would be hauling.

If I was going to be hauling a boat and I mean a large boat around then I would want a V8 with 4 wheel drive. I would have been fishing Lake Erie.

 

The 4.6L engine is a V8.

 

This is why I thought I'd ask someone that knows their engines, I have not keep up with this stuff anymore. Glad you have corrected me on this.
May I ask what is the V6 engine? And what do you feel about that one?
I would be hauling wood mulch about 35 miles about 3 or 4 trips in the Spring and then a trip in the Fall of the year.

 

The only V6 offered in this generation F150 was the 4.2L V6, from '05-'08 if I remember right. Most don't have a high opinion of it, but it's given reliable service to plenty of people. I had that engine in my '03 F150 and thought it was underpowered.

 

I have 167k and never had an issue with either engine or trans. I have an awesome Troyer tune on it and just got 19.1 mpg on 160 mile highway trip going 70mph on cruise control. And that's with 33" tires.

Paid $28k for her new. It owes me nothing.
