LX200

I have an '05 I bought as a leftover in April. I have put about 1000 miles on it in 3 months. The car was built last June, so the oil is over a year old. I will probably have it for 1.5 more years before the oil hits 5000, but I usually change at 3000. Also, with the CAI, muffler and tune, I have driven it nice and hard on many occassions.

Now, I run Mobil 1 in all my other cars. I want to change the oil in the Stang, but I have always heard these "theories" about not using synthetic oil in a car till it has 5000 miles on it. How many of you think this is true? If you do, what kind of oil do you use before you are will to use synthetic?

And if you don't agree, is it OK to go with synthetic at 1200 miles, and what kind do you use?

factory will tell you to change the oil in 3000 or 5000 miles. I bought my car new and changed the oil with fords synthetic blend at 500 total miles, it's a good idea to do this because of the initial break in period. Glad i could help, keep that v6 turnin'.

thats just a myth. couldnt hurt .

Use the Ford recommended SYNTHETIC BLEND for now. Thats what it came with.
Switch to full synthetic after AT LEAST 5K. I am going to wait till 10K.
This is so the parts wear properly.
I have done my oil changes since I was 16 (I'm 47 now) my dad taught me.
My old 1981 Ford F-100 has 287,000 miles on it, never been rebuilt, just had it smogged and it passed-doesnt even burn oil!!
I use AMSOIL synthetic in my cars (4) They also have the best oil filters bar none.

I also did my first oil change at 500 miles due to break in. GOOD IDEA MAN!!

YOUR SUPPOST TO CHANGE YOUR OIL EVERY 3 MONTHS IF YOU DONT HIT THE MILLAGE MARK!!!!!!, the oil breaks down!!!! the oil is like have 3000 mile (5000km) on it after 3 months,

blackfoot

not a myth, the deal is that basic oil, contributes to wear properties that is good for your motor, if you use synthetic right away, it will glaze your cylinder walls, and you may end up burning oil in the futur, go synthetic after the break in! theres a reason!

Im also in the same boat, I bought the car Sept 05 and only has 2000 mi on it and had the same dilema. I have been a master mech. for about 25 yrs. and I always did the break in to all my motors and cars with regular motor oil ( castrol gtx).Depending on motor setup the viscosity differed, so I did a little research and the SHELBYS come with full SYNTHETIC OIL from the get go, If you look at page 84 of muscle mustangs and fast fords, the gt 500 (SHELBY) specs call for 5w-50 full synthetic, thats on the 07's. SO on my 1st oil change on my 2006 Stang, I will be using full syn. IF ITS GOOD ENOUGH FOR SHELBY.......
For cars like ours that are used infrequently, I will use the SYN. I have opened up motors and manufacturing equip. that run on SYN. oil and I was amazed of the minimal wear acumulated by them with SYN OIL - to stnd. oil. Of course it also depends on other variants( LOADS, OP. TEMP. ENVIROMENT ECT...) (HIWAY TO STOP AND GO TRAFFIC) but as to when to change it, I will be doing mine at the 3000mi mark and what the MFRG recommends for oil changes.

but you know that for the shelbys they run the motors on a dyno and get an oil change before they get put into the cars

When we built motors, we would use 20-50 non det to break in the motors, which meant 2000 rpm for 20 mins. after reaching normal op temp. After that initial start up, the oil was changed to remove any crap left over from brake in and we replaced it with synthetic. On motors that were balanced and blueprinted, they were broken in with synthetic, we figured the tighter tolerances called for better oil film on run in. Plus back then Synthetic oils cost us a nut. During that time we had minimal if any problems with what we did. The motors stayed together until a new mod came along and as I said before, they were clean when we opened them up.
