lotta miles
Just bought a 2008 F350 with v10 and 222,000 miles. The engine runs fine. I was thinking about running Rotella 15w diesel oil in it because of the miles. I only put on about 5k a year and thought if the oil was good enough for a diesel it should help my high mile truck to last a few more years. Any thoughts?

I have seen V10's with 400,000 miles on them and still going strong. I have a friend who is a business owner with 4 of these from '99 to '05 all with 250 to 400K and they are worked hard everyday not 1 issue with any of them, they run if properly maintained.

I have no idea how well the engine was maintained. With 222k in two years, that is a scheduled oil change every few weeks. I find it hard t believe anyone that puts that many miles on with the intent to only keep it a couple years would care about scheduled maintenance. Also there is a slight tick that sounds like it may be an adjuster on the valve. I have to get in and figure out what it is. Till then I wanted to have a little extra protection with the Rotella. Also Rotella still has the good stuff in it that has been stripped out of regular oil. I have never heard of anyone with that kind of miles on the v10. You give me hope that I won't be changing the engine. I know they are a great engine, that's why I bought it (it was also a great deal even if it needs a motor). What about Mobil 1 10w-30?

Since the engine runs fine I would definitely stick with the factory recommendation. You don't want to be clogging oil passages with thick oil for no reason. These engines will run forever granted you don't do anything to cause them to break down.

Honestly they have to be highway miles to accumulate that fast so I would not worry much. The ticking could be broken exhaust manifold studs it happens with these modular motors quite often. If you are concerned run some 5W20 full synthetic oil for a few changes, it really cleans up the inside of an engine. Do yourself a favor and stick with Motorcraft 5W20 oil. There really is no need to use any other weight of oil than what Ford recommends, it just will serve no purpose. Our company vehicles get oil changes every 3-5 weeks using a 5,000 mile schedule so it is pretty common. If the previous owner ran full synthetic he may have changed every 7,500 miles. V10's are great engines good luck.

Don't know what the air dam looks like, the truck didn't show up today. it is somewhere between Texas and Pgh. I do know that it was at the auction since December so it hasn't had any miles put on for a few months. I will try to post a picture, but don't hold your breath because I'm a better welder than Computer person. Here is the EBAY link:

Also, I was going to chip it for better mileage, free flow exhaust and K&N filter. Any other suggestions to pick up a little better fuel economy? I'm not looking to race it, just try to get the best MPG. Any suggestions on a chip/programmer? Thanks for all your help.

Yes that one is an early build date, note the very short air dam, I'm not sure if they changed it before job 2 trucks were released or not I can't remember but they extended the air dam a good 4 or 5 inches to help with the abysmal mileage the diesels were getting, guessing the V10 trucks received the same treatment. I don't know a lot about the gas motors but I've seen a lot of guys go with fivestar tuning for the gas trucks.

The best use of your money right now is to send an oil sample to a lab such as Blackstone or ALS. If your wears metals are in line and you don't have any contaminants then there is no reason to change from Motorcraft 5w20. Post back with your results and we can make suggestions from there.

O.K. NO Rotella. I will get the oil tested and run some synthetic through it to clean it out. I'm hoping to get the truck today (probably tomorrow). I was on 5 star website, looks like the programmer for me. I'll hold off on the exhaust for now and just throw the K&N in it with the programmer. Thanks again for the help. This is only my second Ford(my first was a motor home with the v10) Ford has always been a four letter F-word to me but I'm changing my mind and stepping back from Government Motors. This is a HUGE step for me so be patient, I've been a GM guy for 33 years.

Wow, you are the first person to advise against K&N. I've always been a little skeptical about the performance gains that are sometimes embellished. It has always seemed too good to be true that changing an air filter would have that much difference and if it did, why doesn't the factory put them in and boost their MPG figures.

It's not a given that the previous owner neglected maintenance just because he knew it would be traded off in a couple of years. Maybe he did meticulous maintenance as an insurance policy against major failure. I have had several cars that didn't accumulate enough miles before I traded them off to warrant me changing oil every 3k but I have always done that, even on my stroker. The K&N is a definite no-no on a diesel because of the extra suction from the turbo. Not so much on a gasser, but I would think twice about it.
