What type of engine oil do you use?

[MustangBoy28]

My 2006 has about 48,500 miles on her and I've been using 5W-20 like the user manual has recommended. Do any of you use anything different? And is it safe to start using a thicker oil once I hit a certain millage?

I have 2001 with 225000 miles on the original motor, and 2005 with 100000 on original motor. Always used motorcraft 5-20 and only motorcraft 5-20. I am not a believer in changing brands or viscosities.

Hi MustangBoy28,

I agree with armoore98 in sticking with the recommended oil per the manual. Motorcraft mixes quality materials, product integrity and customer satisfaction. I suggest continuing to use Motorcraft.

I use Royal Purple in every engine. As for switching weight, don't the VCT may be affected.

+1 for Royal Purple 5w20. I even use RP in my Armada.

I would also use it in my 2001 mustang gt.
