Royal Purple or Mobil1 Synth. though once you go synthetic on the motor(or anything else i believe) you cant go back to regular, itll sludge up or something like that.

Id recommend changing out tranny and rear end as well, you will feel a nice difference on the butty dyno, it will free up some power lost by crap lubricants.

Well this has been well talked about subject. Were I agree with all above that Mobil 1 is good oil, the fact remains the difference between synthetic oil is more about price than anything else. I prefer castrol simply because I have trusted it for 25+ years. Here is a link and what I posted a while back

Here is something to think about . The saying you should not switch brands of motor oils was true at one time. Some Oil companies used wax based products in the oil to make it viscous (thicker). Not a good thing!!! So changing it around 3000 or so miles was good and wise.

The reason for changing non-synthetic oil is it breaks down do to heat and gets contaminated with acids and ash from the residue that gets by the rings during combustion. These contaminates will corrode and etch the machined surfaces in the engine and cause bearing failure and premature wear.


Synthetic oil is a bit different it does not break down. Originally developed for jet engines that produce very high temps and spin at 30,000 rpm's or better, standard oil would not do. Some of the benefits is it really does not break down so in jet engines you dont change the oil unless water gets in it. Automobiles on the other hand still have contaminates from combustion so you have change it. I will point out though, several boat and car racers I know do not change the oil, only change the filter. I dont recommend it but there are people who swear by it. I change my synthetic every 7000 miles, if you change it every 3000 miles or so you are wasting oil. But hey its your money and your right to change your oil as much as you want. There is no major difference in synthetic oil so any brand is OK to use. For me I prefer Castrol but thats just me.

I use Mobil 1 as well, but was once a Valvoline guy.

I used to work with a guy who told me that. I thought he was blowing smoke up my ass but maybe not eh.

He claimed that as long as you changed the filter, the comtaminants would be strained out of the oil.

btw.. as per the oil caps mid 02 and up mutang GTs call for 5w20, the other years call for 5w30... I always used 5w30 motorcraft synthetic blend oil in my 02 GT

That only works with synthetic oil because conventional oil breaks down do to thermal breakdown and loses it's vicosity. That is bad.

I am the oil company's best friend...I change mine every 1500-2000 miles. lol It gives me piece of mind, so it is worth it to me.

just went down and seen mobil 1 has a oil that you only have to replace 15,000miles or 1year what ever came first and they stand by it. Has anyone tryed this oil? Called I think mobil 1 extented?

Corey, synthetic oils do break down, not nearly as much though. Every time I get new oil my oil pressure guage does read higher oil pressure at idle. As I get close to time where I change my oil, that pressure has indeed dropped...

[rocknbronco]

I use Amsoil once a Valvoline guy remmember you factory oil from Ford will be Motorcraft its a semi synthetic I would pay the extra bit and go full synthetic.Last longer and you get better milage from it and way less wear also keep the weight in the 5W20 or 5W30 range .

How about Lucas oil?
