I have an 07 GT manual, i am currently running convential oil....is it worth it to switch to synthetic? Any input would be great....advantages disadvantages? Worth the extra dough?

 

yes

 

Search the site for Mobil 1, Redline, Royal Purple and you'll find a pile of info.

Me? Redline believer, but my new home area has no supply unless I mail order, I think not, hassle, expense, so after some 300k plus miles of Redline use, going to Mobil 1.

I also and a firm believer in "Tufoil" www.tufoil.com which I've always had to mail order.

 

no

 

Yes definately worth it over the motorcraft semi synthetic.

 

Yes, synthetic motor oil provides increased protection for your engine, and can help increase performance with it's additives.

I recommend mobil 1 5w-20. Good on gas mileage, and good protection, as mobil is one of the best oils you can buy.


As for oil filters, get a good one.

JSYN, fram was rated one of the worst as they lose their filtering ability after a short while, and reduce oil flow.

Among the best are motorcraft (yea, I was surprised also), and I think acdelco.

 

Filter Comparisons

 

As always, howarmat came to the rescue.

Seems like I messed up the ACdelco filter, haha, it's last!

So, what I get here is that mobil 1 5w-20 and the motorcraft filter is the best for our cars.

But, how often do u guys change your oil and filter on a DD?

 

thanks for all the input guys....i know a decent amount about oil and stuff....i posted this thread because just about everyone i talk to has a different opinion one being "dont waste your money on synthetic" and then the next "i would never put anything but synthetic in any of my cars" so i just wanted to get some more input....so anything else would also be greatly appreciated thanks again!!!
