I finally got my FRPP Sport exhaust in and am planning on going over to a friend's house on Saturday to have him help me install it (he has a lift).

Should I go ahead and change the oil over to a full synthetic while the car's in the air (my car has approx. 600 miles on it) or should I wait?

If it were me, i would change with regular oil, drive another 2K, then switch.

[replica]

Sure. I wouldn't.

[powerwhee]

No point in changing it unless you want to. My first oil change was at 6500 miles and my car is fine.

Change it if you like, but don't go full synthetic till you get more miles on it. My engine didn't feel like it got settled in till it got about 9k on the odometer. I still have dino in it, maybe 4 or 5k more then synthetic.

[Intense]

There is not a lot of break in on modern engines. I'd at least wait until around 2K miles and, even then, just swap out the factory fill with the 5w-20 Motorcraft syn blend and another Ford filter. I think of it like sanding (bear with me)...rougher grit, then finer, and finer. Get the factory fill out, then fill with the oil and use filter that I mentioned...but change it before 5k is on that oil too, then go to your group 4 synthetic (a true synthetic -IE, doesn't just say "synthetic" on the bottle). I think the Mobil 1 Extended Performance oils are Grp 4's. Amsoil full syn's, and some others too. The info is out there. "Bob is the Oil Guy" is a great site to ask the more knowledgeable or search for answers.

if you feel like throwing away $50 just paypal me at 2011fastford@gmail.com
in all seriousness no reason to change your oil, you can also install your axle backs in about 30 minutes with a jack.. but of course lifts are great to

I would and did. I ran semi-syn for another 3k then went to full synthetic. You'll read other opinions...do what helps you sleep better.

old school opinion

[hammergjh]

In a word, no. Waste of money, time and resources. However, as winter is approaching and full synthetic oils perform much better than dino oils, it might be worth it for that. I'm running RP 5w-20 in my car since about 5k miles (when I did my first change).

[Strange Mud]

let us know what you picked.....

[mustangkid9234]

Wait wtf why not switch to full synth then? Just curious

[David Young]

I got a coupon from my dealer a month or two after 'Little Red' came in, for a free oil and filter change. The coupon had a couple days left before it expired, i had 499 miles. They changed the oil and filter. I didn't change to full synthetic until 2,000 miles.

Change your oil anytime you want. Whatever makes you happy

[sandpiper]

Absolutely not. Check the level and fill if necessary. Change it and there's a good chance you'll have an oil burner at 30K. Just my opinion (with experience)

I'd go at least 2000 miles then change it with semi blend for another 3k then spend as much as you want on full.

[Strange Mud]

Kid, I believe (don't know) the full syn lubes better but do want my engine broken in so I did the 1st at about 500 miles, the 2nd at 3-4k miles both semi-syn. After that I went to full syn. This is one of those subjects you'll get multiple opinions on with very few facts. I'm old school and this works for me but in the real world I don't think which method you choose ie: change it early or when they recomend, drive it hard or break it in without redlining it for the 1st 500 miles, will either make or break your car. Ford does recomend the treat it gentle for the 1st 500 miles and does not suggest you change your oil early. They are smarter than me. I changed the oil early and broke it in according to the owners manual. Alot of what is best is what YOU believe...
