I'm the third owner that I know of. The guy I got it from had a shop do all the work so I know they used the same oil every time. Just don't get why you would run a blend instead of going full synthetic.Thanks idcwby

Got a 91 F250 with the 351W about 140000 miles on it. The previous owner used 5w-30 synthetic blend oil with Lucas additives. When I go to change the oil should I stick with that or just go full synthetic?Thanks idcwby

Thanks for the information everyone. After getting to look over the diesel, it wasn't worth the money had more problems than the guy was telling me over the phone.I did come across a good deal on a 91 with the 351 and auto transmission, it's only down fall was the power locks don't work. I...

Shawn with the gas motor, running non synthetic oil I'd probably change the oil every 5000. With the diesel, since I'm not working it very hard probably change every 10000. So they would almost cancel each other out for those costs.If it's below freezing, is the IDI going to have difficulty...

How often have you had to put in new injectors and injection pump?My biggest debate at the moment is which would do better on fuel when towing. The 6.9 that I'm looking at has a gear vendor over drive and the ats turbo. The guy is claiming he can get around 17mpg empty down the highway at...

Thanks for the input. I think there both up to the job, just trying to decide which would get better mpg when towing. From what I've been reading they both get about 15mpg on the highway and I'm assuming that's unloaded. Trying to determine it the diesel is worth the extra cost or will it pay...

Bill's third option is out of my price range at the moment. Doesn't mean there not out there, but I haven't seen one yet with a long bed. I had been looking for a 351 and than I ran across a good deal on a IDI, so it got me thinking what would the better option be. As far as diesel vs gas, I've...

Just out of curiosity what would you choose if we're buying a 4 wheel drive pickup, that would mainly be used to tow 2-5000lbs down the highway and in the mountains? The IDI has a turbo on it and 5 speed. The 351 has a 5 speed and is carbureted. Both Ford trucks about the same years.Thanks...

Thanksidcwby

Thanks for the info. Anything that was probalamatic with this year of pickup?idcwby

Even with the carb I should still be in the 15mpg ballpark? Would pulling the fuel injection affect the air conditioner, cause when I test drove it, it didn't want to work? I'm still very interested in this pickup because the price in its real good, so I'm trying to learn as much I can before...

Its got a manual 5 speed in it, which is one of the reasons it peaked my interest. I was going to get it for hauling a trailer and sidexside. Is the fuel mileage going to be lower mainly because of the carb?Thanks, idcwby

After talking to the dealer some more. I was informed that the fuel injection was removed and the carb was installed, trying to make it some sort of "hot rod," but the person ran out of money to spend on it and could never get the holly tuned correctly.idcwby

Hey everyone. I'm looking at buying an 1990 F250 with a 351 in it. They have taken the fuel injection out and replaced it with a Holly 4bbl carb. I was wondering if this would cause any issues? Is this common? Should I avoid this truck because of this? I'm guessing it has about 150,000...

Hello everyone. Signed up to ask some questions about ford pickups. After buying a sidexside last year, the little Toyota pickup isn't the best for towing it and now I'm looking for something bigger to get down the road better.idcwby
