Hey guys! Please Help!
I have a 99 GT and When i last changed my oil i used synthetic. I started talking with a buddy of mine and the subject came up that when you use synthetic you must use it from there on out.
My question is how hamful is it to switch back to regular oil if this is true.
Thanks in advance......

 

Its a myth. You can switch back as much as you'd like, but the question is why? Synthetic offers much more protection than conventional oil and is a lot better for the car. For the few dollars you save its going to cost you in the long run

 

Thanks alot for the advice.

 

S-16 is right u can go back and forth it makes no difference, i like the blends infact ford recommends it for the 06, for yor 99 i like the cost of blends but its up to you, good luck.

 

Thanks! You guys are awsome...

 

just use some wal-mart syth. oil it's cheap and good..no joke

 

ditto X 3
