    Any other G/M or C/V owners using the Back engineered 5w-20? I have read on other forums where it causes premature engine wear. And Ford is only using it to meet the CAFÉ standard. I started using it 2 months ago in my 2000 G/M no problems yet.

    I dont want to sound lazy but can someone give me their input on using synth 5W20? I am currently using it but I was always a castrol 10W30 and 40 person. Thicker oil in the summer.

    I have a 1994 Mercury Grand Marquis with about 119,000 miles on the odometer. I discovered about a week ago when I checked my oil level because the oil light came on that my oil level was quite low. It took three quarts to bring it up to the full line on the dipstick. Yesterday I added about three more quarts.

    Not being a mechanic myself, I always thought that if a car was using oil, you would see it and smell it. Not so in this case. What could be wrong to cause the car to start using that much oil with no symptoms? How serious/expensive could it be?

    Thanks!

    The most obvious sign of a car using oil is a puff of white smoke when a car is first started after sitting shut off for a while. In this case, worn valve seals permit seepage of oil into the cylinders.

    In worse cases, a cloud of obnoxious white smoke appears whenever one accelerates. Real oil burning vehicles are therefore easy to spot.

    The CV and GM recommend a transmission service at 30,000 miles. I have read all the pros and cons of the usual drain or the power flush. What do most of you do? i think it is important to drop the pan and some say the flush can cause problems.

    In 90k miles the tranny oil has been changed twice. When it starts to shudder again, it'll be changed again. The first change used Mercon V Synthetic. The last change used non synthetic, a lot more economical, and can't tell the difference. This is regarding our 95 T Bird with 4.6 and AOD tranny.

    The 94 Town Car has 127,000 miles and is still going on it's 2nd change.

    Just be sure to drain the torque converter too. Drop the pan? Wouldn't hurt if high mileage.

    tranny fluid in my 2004 CV at 30,000 miles, complete flush, changed to synthetic tranny fluid, dropped pan and changed tork converter...

    While I honestly did not see any improvement in tranny performance, I do not expect to, any more than chganging engine oil shows noticeable improvement...I just do it for routine maintenance, hoping that the tranny will shower me with $150K miles of service or more...

    A clean tranny is a happy tranny...:):):):):)

    I've heard from a few mechanics that tranny fluid should never have to be changed for the life of a car. My '85 Grand Marquis was, and '80 Trans Am is, running original tranny fluid with no signs of performance degradation. It may be a different story for new cars, though; more compact designs with more electronics may require more frequent changes, but every 30,000 miles seems kind of crazy to me. I guess it's just the automaker covering his rear (speaking of which, a rear end fluid change strikes me as unnecessary in most cases, too!).

    I can appreciate your view, but I just cannot see leaving any fluid in there that long...to me, tranny fluid gets as abused as engine oil, but we go longer because it is 18 quarts as opposed to 5-7...but, hey, thats just me...
  • marsha7marsha7 Posts: 3,666
    was the color of the fluid the same as your coolant???... if yes, could there be a water pump leak that drains along the block and falls somewhere that does not directly correspond to an area of leaking???...kinda like the roof that leaks at the left end, but the water drips and falls on the right end, the true leak is nowhere where you find the evidence of the leak...
  • p2minp2min Posts: 3
    Yes, I use the coolant that mixes with all coolants. But I have always kept the same color.

    Thanks, I have a water pump leak and I will replace it. Thank again for your help. I hope this fixes the problem, because the car runs cool.

    Are you sure it's Ford who is recommending the tranny flush, or was it a dealer? Because I had a dealer tell me I needed to do it, but I could not find any such requirement in the manual. I have an 03 GM.

    Hello everyone. I'm new to this forum and I have recently purchased a 1998 Mercury Grand Marquis GS with 29,400 miles on it. An older woman owned the car. It has been garage kept and probably hasn't been driven much the last three years.

    This is my first Panther car and I'm not the typical age of MGM owners. I was going to give it a checkup. I know for sure I want the transmission fluid drained and changed in addition to the coolant. Is there anything else you guys think I should get checked out or be conscious of since it probably hasn't been driven more than 3,000 miles the last three years. Thanks in advance for your reponse!
  • Dear Gobig,

    Nice to hear of someone else close to my situation....my purchase was of a '94 MGM GS with only 23k on it. I replaced the wiper blades, brake pads, and flushed the coolant system myself. I took to the dealer to have them flush the transmission. It had that stuttering vibration at 52mph because the previous owner didn't use the proper fluid when he changed it. The flush took care of the problem. I live in FL with hot humidity and am weary of anything rubber as I can tell by touch it is rotting. I also dealt with a leak. Everytime we get a bad rain, the right rear of the car fills up with water. I've taken the floor board plug out for drainage. I've had the car in two different dealerships over the issue (it's leaking around the firewall/AC unit) and have spent a few hundred bucks on it....to get no results. It seems worse when the car is parked on an incline with the trunk lower than the hood. So I sometimes back in to my parking space and this seems to do more good than anything. Good luck with your nice ride!

    Thanks for the info! One other thing I recently noticed is on the passenger side of the car I hear something "flapping" in time with the rotation of the wheels. If I drive slower the flapping goes slow. As I speed up the flapping speeds up. I didn't notice anything sticking to the tires or protruding out from the side. I realize this might sound stupid. Anyone else ever have this?
  • I too have the "shudder", "jolt", "hippity-hoppity", 'shake you half to pieces thing' in my wonderful beast. I really shouldn't complain as the car was given to me as a wedding gift and other than the shake down thing, she works great.
    The RWD thing takes a bit of getting used to as my last car was a '90 Pontiac Bonneville.

    I have just discussed that last suggestions of tranny and torque converter flushing with my husband and we will definately try this as we have no record of this being done.

  • My '94 GM (now with 205k miles)had tranny shudder at about 2 years old and 34,000 miles. An independent transmission place told me to put Chrysler trans fluid in it because it contains some kind of additive to reduce friction, which the Ford fluid did not. Never had the problem again.

    My father was attempting to replace the fuel pump. During this process, the fuel lines on the fuel pump broke off in the quick connectors. Fuel lines all the way to the engine compartment are very rusty. He is wondering if anyone has any suggestions on the best way to go about replacing the entire fuel lines.
  • Great start to the New Year. Last night driving home in my 2000 GM an apparent mis-fire started. Seems to be at any load, but still accelerates reasonably under full throttle. I was thinking plugs, leans etc. Then the temp gauge went to max for a second or so before returning to normal. Did this a couple of times on way home (8 miles). Also, the traction control light came on and stayed on.

    This morning, the 'check engine' light came on.

    Any suggestions?
  • FIXED IT!

    Don't know what caused the Temp Gauge flick, or TC light to come on, but I went to Murrays, borrowed their OBD 2 diagnostic gear, said No 8 misfire. Changed No.8 coil. now fine!

    Glad that was cheap and easy ($63 inc tax). I also treated it to a new set of plugs, as they weren't too great (though color was fine), they are due for replacement at 100,000 miles (car's done 85,000), and they were only $24 including tax.
