Hello,

thanks to all of you for the help I have already found in this forum!

I just bought a 2000 Excursion Limited, 4x4 V10 a few weeks ago.
I would like some professional opinions on what I should be doing for oil?

I switched my 1991 volvo 740 turbo over to synthetic at 190,000 and it now has 245,000 with no problems. I like the idea of synthetic, but am not sure if it is right for the X.

Here is the deal - I bought the X with 207,000 on it, but it has a new transmission (installed by FORD dealer) 11,000 miles ago, and the engine was rebuilt at 185,000 (also by ford). the head was replaced at that time as well. - I DO NOT KNOW what the previous owner was using for oil

My question is if I should (or if it is a good idea) switch over to synthetic, and if so is there any procedure to go through or things I should be concerned about? The mileage does not seem to be what it should on this beast - 9mpg? I got almost 12 towing the volvo back from MA, but am consistently at 8.5 - 9 now around town unladen. Thanks for the look and the help in advance guys!

Aaron, synthetic is fine in the V10 and there's no special procedure. Drain it, put on a new filter, and fill it. The 2000 Excursion owner guide calls for 5W-30 in the gas engines, 6.0 quarts with a filter change (Motorcraft FL-820-S filter), and it doesn't require synthetic, so a full synthetic 5W-30 is a straight swap. Mobil's own advice for a higher-mileage engine that has never seen synthetic is to do the first oil change or two at normal intervals before you start stretching them. Your engine only has about 22,000 miles on it since Ford rebuilt it, so you're not switching an old, sludged-up motor anyway.

On mileage, 8.5 to 9 around town is on the low side. In this club's v10 milage thread, owners of 2000 V10 4x4s report roughly 12 overall or around town and 14 to 16 on the highway, though Jim's 2000 4x4 in the same thread was down around 9.5 at 55 to 60. Keep in mind those are mostly off the trucks' own readouts, and tire size changes what the odometer reads. One owner there runs 285s and says others have found they make the readout more truthful. Check what size tires you're running and keep them at the door-sticker pressure before you chase anything else.
