Default following manufacturers specs to the letter

Call me crazy but I've decided to check my owners manual and follow the reccomendations. I have an 07 Mustang GT very low miles 12,400 of which Im the second owner. Its been in storage for winter but when I get it out for this spring I will use motorcraft syn. Blend 5w20, and Motorcraft FL820S Oil Filter. Can't go wrong

I prefer to use true synthetic 0W-30 to 10W-30 lubricants that are barely over the 30 grade viscosity standard. Amsoil, Royal Purple, Red Line, etc...

The engine wears less and you gain mpg.

laughed reading this...I got all into 'oil type/brand A vs. B' in my previous car... I decided the motorcraft syn blend and filter every 5k miles was sufficient in this car when I bought it...4.5 years and 60k miles ago. no difference than if I had paid $s more over the same time period for something different

im a little confused.. you say they use a lighter weight oil to gain mpg but the 5w-30 has actually increased mpg?

I have a 07 with 13K on it. I use Ford Synthetic oil too but i change it every 2500 miles cause I worry about the Turbos effect on the oil. with the turbo being oil cooled.

Deerborn doesnt know if I live in Arizona or Michigan.... so I always do thinner faster flowing oil in the winter and thicker heavy oil in summer. Its been -12F here in December and 111F in July soo...

10W30 winter and 5W20 in summer.


on my motor cycle I used Kawasaki brand oil and used what was called for, but later switched to Klotz racing oil. It was red and smelled like candy : )


and I simply dont trust recycled oil ....yet.

Man I am right there with you and it can sound nuts but you know what. I run all motorcraft products in my 2013 and I ran them in my 72 Mach1 before I started restoring her.

I think for me its more of a being true to Ford and all of its products sort of thing. Making it as athentic as it can be.

Should look into having oil samples tested by a lab like Blackstone to determine if that is overkill or not.
