    FYI Motorcraft Synthetic 5W-40 Engine Oil

    I agree with jet. To add to the point of extending your oil change intervals, it's cheap insurance to stay with regular OCI. My PSD is stock, I like the advantages of synthetic so I run it and change it every 5000 miles. May be stupid but I view it as cheap insurance, and based on everything...

    FYI Motorcraft Synthetic 5W-40 Engine Oil

    Synthetic is great! It has many good points, but extending your OCI under any circumstances IS NOT RECOMMENDED!!!!!!!!!!!!! This is what many of the best Ford mechanics have told me OVER AND OVER AND OVER!!!!! "The only way to safely extend your oil change interval is to increase the capacity of...

    Experience w/ Schaeffers oil

    Trying to get some input on Schaeffers oil. Don't see to many running it however, I don't see any negative comments or results from people using it. I'm curious to see what kind of problems or lack of problems people running Schaeffers have had while using the oil. How many miles have you been...

    Mobil Delvac 1 vs Mobil 1 Turbo Diesel Truck

I've been trying several different ones (mainly synthetics) trying to settle in on something that gives me the best economy and is a good quality oil, as well as is not is not a pain in the butt to get and doesn't cost a stinkin' fortune. Would prefer a...

    water in diesel

    I get the water in fuel light from time to time but draining the filter housing doesn't seem to help. I always have to have the housing taken apart and cleaned. It seems to have this substance that looks like partially dissolved dookie stuck inside the housing, is that bacteria or just trash and...

    OK, just filled up and my milage average was 12.34 miles per gallon. Up to now my milage for average around town driving has been between 10 and 12.5 with somewhere around 11 being the most consistant number. This appears to be in the same range it has been until lately. Last few fillups milage...

    doodad mod works

    Well thanks for the honesty and time responding to my questions. To many people are trying to capitalize on high fuel prices with BS gimiks that only make them money and don't work. Heck, I've seen some people claim great results on things they bought just because they were screwed and it made...

    doodad mod works

    Just like to get good input before modifying anything. Too many times have I spent money, made modifications, bought a different more expensive part, only to see NO difference. That's why after years of "Put a K&N on it," or "put an aftermarket dual exaust on it and it will improve your milage,"...

    doodad mod works

    No problems driving at interstate speeds in a hard rain? What about milage improvements on a stock truck?

    doodad mod works

    Are you saying that you do see measurable results on a stock truck? My average milage seems to be getting worse and worse, down to about 10.5 miles per gallon after cleaning and reflashing turbo so looking for an edge. What about the rain, do you have to worry about water getting in?

    doodad mod works

    Does this mod really do anything positive on a stock truck, no BS now tell the truth. I know you guys like it but any performance or milage improvements?

    What is fuel costing you?

    First people are losing their houses left and right because of greedy crooked loan sharks and now businesses are going belly up because these guys won't allow us to drill on our own soil. I know this sounds anti American but, sometimes I wonder if we would have been better off if the World Trade...

    What is fuel costing you?

    The price here in Burlington N.C. has gone from 4.59 to 4.79 overnight. I paid 4.39 last week then saw it for 4.25 the next day. So, basically it has gone up on average 40 cents in one week! Can somebody explain why diesel is $1.00 more than regular gas...

    06f250diesel Yeah, that's what I've got, but Bush's comment was that you should be on your second by-pass filter so I'm confused.
