Go synthetic. Conventional oil is garbage. Science is smarter than nature

I run Royal Purple 5w20 in my 02 GT w/ 99,900 miles but did have Mobil 1 in it for years.

see but you ran synthetic in it for a long time so it mostlikely took out most of the conventinal thats in it, and yeah synthetic is better but like i said earlier i said it is better to run it on conventinal if thats all that has been ran in it, and you will be able to tell a difference if you switch oil, you will start hearing sounds that you have never heard before and it could be something wrong or there will be nothing wrong at all, and if the switch did work for some ppl then great for them. but if you do switch and it starts to run crappy switch back to conventional. have fun do what you want you dont have to follow or believe my advice. so have fun with what ever you do.

What oil should I use for my 07 v6 Mustang?

I was under the impression only certain cars can run synthetic oil... Can mine run it?? If so what do I use?

well it should say in your owners manual, i believe that they still put in conventional but im not sure. if yours doesnt have too many miles on it since it is newer you should be fine.

Just use whatever it specifies in the owners manual when in doubt. Ford didn't spend millions of dollars designing your engine just to turn around and tell you to put harmful oil in it.

There is a lot of hocus pocus around this topic, its pretty funny actually. While scientifically synthetic oil is "superior", unless you are racing through Death Valley on a regular basis, not changing your oil for 10,000 miles, or running your car through the 24 hour LeMans circuit, you'll never see a difference IMHO.

I have run 100% synthetics, dino oils, blends, etc, across 20+ different vehicles over the years. Some were sports cars, some trucks, etc, and I've lived everywhere from IL, TX, AZ, UT, WA during that time. Everything from constant mountain driving to nothing but flatlands. I just simply have nothing to backup the notion that using synthetic in any situation ever made a difference at all. I wish I could say I did, considering how much $$$ I spent over the years on synthetic, but I just plain do not.

Again, when in doubt run what it calls for in your owners manual. If putting synthetic in will make you sleep better at night, then maybe its worth it to you. As for me, I go by the book these days.

That said, always buy a high quality oil filter!!

I have a 2003 Mustang Coupe and I am using synthetic blend right now. I've been doing that for a little over 2 1/2 years and am about to go to full Synthetic. I now only have to change my oil every 10K-15K instead of every 3K. I've had my stallion for almost 5 years now (bought it new) and never had a problem.

I'd say phase it in, blend then go full.
