over the past week or so i have noticed that my duratec was really lacking power. usually when i mash the gas from a stop it will get a pretty good spin of the tires, but lately it hasent been doing anything, not even a little chirp. the car doesent even pull that hard in the upper RPM's. i started to notice that i had close to 3000 miles on the oil, but i didnt think much of anything of it until it came closer to time to change the oil. well right after i changed the oil i tok the car out for a drive, mashed the throttle and lit the tires up with lots of tire smoke


has anyone else noticed this kind of sensetivity when your oil gets dirty? i mean, this was like two completely different engines, ive never seen a car so particular about its fluids.

i just thought it was kind of odd and thought i would share

I can tell when my oil is getting old the same way. It's not quite as drastic as you described, but noticeable.

I would bet the farm that your duratec's sluggishness has nothing to do with 3K mile old oil.
You can leave it in for 5K and never feel a difference.

Don't know what kind of mileage you have on the bull, but a tune-up might help.
I'd also check to see if any trouble codes are present.

i only have 12,000 miles on the car, just got it in july. i didnt change anything but the oil and i noticed a drastic difference, as did some of my passengers. like i said, i didnt change anything else on the car, and after changing the oil it ran alot better than it did in the 30 minutes before i changed the oil. i cant think of anything else it could have been.

On my '93 SHO I can tell when the oil needs changing. After driving home from work on the interstate and coming to the first stop sign if the oil has over 3k on it the oil light will flicker as the idle dips. Only does this after the viscosity starts to break down.

I noticed it on mine but I just got the car and the oil had unknown mileage, no name filter and looked due for a change. After just an oil change with some penzoil 5w-30, a new motorcraft oil filter, and a new fram ail filter the thing sounds and performs much better. I even got a little chirp out of my vulcan. I cant wait to see how it responds to a coolant system flush, a tranny flush, and a new tranny cooler this weekend.

Speaking of tranny flushing...i have a rebuilt with maybe 30,000K on it....should i flush it because its a rebulid? The fluid is still blood red, but it drives like crap when its hot...hmm..maybe a coolant flush would get rid of that gutlessness..i dont know

but im open for some opinions. <_<

I did my second oil change at 5500 miles on the car and the oil was black. I did the first one at 3000 miles and this one at 2500 miles. Now that I put in full synthetic the car likes to rev a little better due to the thinner oil. It wasn't as much of a difference as the intake silencer mod, but it was certainly notticable. As for gas milage I was getting 15-20 in the city depending on where and how I am driving. I will know in a few weeks if there is much of a change. And yah, please do something with your tranny oil even if it does look good. I am sure there are metal particles on your magnet too. I doesn't take much...

This doesn't sound right, Paul. My 95 SHO never does this. In fact, I've never heard of any SHO doing this except when the main bearings are bad. How old are your main bearings?

The bearings are a little ove a year old. The oil pump is worn out I fear.

I remember seeing somewhere about a dyno test being done to see if you in fact do lose horsepower with dirty oil. Well, there was a slight increase in power (lost power, not additional power gained). So perhaps its possible, weird that it's so noticeable on your car hoss. Maybe the temperatures were different? Colder engine? I've noticed that I can't usually spin the tires unless the engine is still somewhat cold or it's cold outside. Usually I don't have to hit the gas all the way either. So weird...

You guys having this problem with old oil, is it because you use conventional oil? I don't really have a problem with Mobil 1 and k&n filter.
Every time I change my oil (3k) with my vulcan I always notice the slightest bit of pep for roughly the first 25-50 miles after the oil change(M1, M1 filter).
