Ford 6.4 liter diesel

[Thekipkers]

my friend and mechanic advised to stray from the 2008 job 1 6.4 as they had the most issues.

I purchased a 2010 with 90k on it, the truck already had the DPF delete and a tune, truck pulls good and haven't had any major issues.

I Ok, now that we've headed down that rabbit hole... Diesels need more attention paid to maintenance. Most people blow the head gaskets due to over tuning. Not saying that is the case in 100% of the cases, but way more than half. When you build up too much pressure in the in the engine, it will find the weakest point (gasket) to escape. Before you buy it, take it to someone you can trust or at least someone who works on Diesels to check it over. This is no guarantee, bit still better than just taking it on faith. When I bought mine I had every fluid drained and replaced. This way, you know everything is fresh. Then change the oil every 5000 miles with T6. I add Archoil 9100 in my oil. Whether you use that or not, still change it! When you change the oil check all of the pther fluids. If they look borderline, change those too. When driving, try not to go above 30psi on the turbo. It can go to 40psi,but like I said above, the more pressure the higher the chance of problems. You occasionally will go above, but if you aren't racing people off the lights it will be rare. Take care of your engine and transmission and they will take care of you. I love my 2008 6.4 and I have had no problems during its 190,000 miles.

I must be having a lot of good days. Towing is 10.1 mpg
Non towing is 12 mpg

Everyone is correct about maintenance? I probably over think it but no breakdowns.another major item to keep clean is fuel filters.

1600 miles in June and 10.1 is what I got, before we left on the trip it was at 12.2 MPG which is better than last year when it was down to around 11.4 not towing and 8.2 MPG towing for 3400+ miles.

Stock settings still.

If the six speed transmissions I have looked at were not so expensive I would have one installed to see where the mileage ends up.

Thanks for all the advice. I ended up with a dodge 3500 diesel with the 6 speed manual. I moved up 4 years newer.
