Thinking of going fully synthetic. Engine, transmission, rear end. What could I expect for gains by doing this?

Also what weight oil, for the rear. Yes I should probably do a bit more research first, but figured I'd pose the question here. Thanks.

 

at least 50 hp...

 

I just recently changed over to full synthetic mobil 1 motor oil Sunday. It was the 3rd oil change, had used Motorcraft 5w-20 on the first 2. Car seems to run smoother to me, but it could just be my head making me think it is :P.

 

How many miles before you should change to synthetic mobil 1?

 

REALLY?

 

yeah, right! I doubt that. Would be nice, though.

I looked into doing the same. The rear is already synthetic...and with the friction modifier added it probably won't help to change. I called Mobil1 about their synthetic transmission fluid...a no go for the Ford Mustang spec. I would expect 2-5 HP changing the motor oil to synthetic since the Motrocraft blend is only 5-10% synthetic. Good luck with the Royal Purple or Amsoil folks.

 

i dunno about 50 but i did get at least 8-9 by taking a mist gun and spraying my K&N with water

 

Will it make the engine run more quiet ?.

 

What are you guys using? I know M1 makes a 5W20, but it is hard to find. Murray's Auto had it, but only 2 quarts. Is 5W30 good to use?

 

The best products I have found are "NEO" oils.

They make a 0w-5w engine oil.

They also make a 7w gear oil for trans & rears. It may be called "18" now.

I have used their products in cars with as much as 650hp with no problems.

You will feel a difference.

Wow, 0w-5. That's some thin stuff
