2006 Mustang GT oil change question

[FordSVTGuy]

Hey all - Just purchased a used 2006 Mustang GT from a dealer and I am not sure of the oil change or other maintenance history of the vehicle. The oil is clean and full, but I know that the car was sitting on their lot of at least 9 months. I suspect that they serviced the vehicle after it first got on their lot, so that would make it 9 months old (with little to no miles on it). I would love to hear from you all regarding your recommendation to run the oil or dump it in favor of the Mobil 1 5w20 I have ready to go.

It is a sweet ride and you can't help but step on the gas!!!!!

Nice Car---I would change the oil immediately for peace of mind--why wonder when it was changed last? In fact if it were my car, since it is 4 years old I would flush the radiator and change the transmisssion fluid as well. Why not establish a good baseline and get the exact type of fluids you want in your car?

When I bought my hemi Charger, it had been on the dealer showroom floor for about 18 months. When I signed the papers, I told them to change the oil before I picked it up later that day and that I wanted either Mobil 1 or Pennzoil Platinum in the crankcase. That afternoon, I arrived to find that they hadn't done anything. So I told the service manager if he still wanted me to buy the car that they'd credit me $40 to have the change done by myself at a place of my choosing. The manager walked out and took $40 out of his wallet and handed it to me. I hit Walmart and Napa on the way home and 30 minutes later it was running a Wix filter and Pennzoil Platinum 5W-20.

Dump it and put in what you want. That way you don't have to worry about it.

We bought a car recently and that's one of the first things I did when I got it home.

What about the trannie and the differential? Motorcraft oil would be just fine.

Congratulations, I love my 06 Mustang GT. I agree with changing the oil out. I use Pennzoil Platinum 5W20 in mine but Mobil 1 would be great also. Concur that you may be due for transmission service, fuel filter, coolant, etc. Mine has a Ford Racing Performance Products axle back, plus recently a JLT cold air and a custom dyno tune. The tune really perked it up.

Thanks for the comments. It has only 25,000 miles on it, so I am not sure about the transmissiony fluid. I always thought that was miles based not time, but I could be wrong about that... I am going to dump the oil and start with fresh Mobil 1 and a Motorcraft filter.

That's one of the first things I do after I buy a car. Change all (applicable) fluids. It's good to know the history.

ditto. Known history makes any used car more valuable.

We just bought an 85 Mustang GT Convertible from the original owner. An Arizona/Florida car with a huge file folder containing every receipt for anything ever done to it.

Gotta find those BITOG members out there!

It's easy to be skeptical of how a $2.77 qt of oil could perform so well, but CP and Ford thoroughly tested it.
