Engine oil RED LINE or Motorcraft

Motorcraft 100% Pure Synthetic Oil and motorcraft filter.

Red Line.

I like red line oils, because they have a bit more zddp which is nice for the rockers.

I use 5W-30 Motorcraft

On chilly winter mornings (SF Bay Area) the car did not like reverse or first gears. Subsequently switched to Red Line engine oil. More power, better mileage.

I'm using motorcrack 15 40 in my 3.0 Taurus. It's been great for years

Ran Redline 5w40 when it became purely a summer car in ~2013. ... Not seals are leaking, no issues of any form. Car has been Cobb stage 2 91oct tuned (OTS, not pro-tuned) almost 14 years, with a Crawford v2 AOS, Killer B oil pickup + windage tray being the only reliability mods, and it doesn't burn a single molecule of oil.

Redline is great, used it for years in a track car.

My STI also used it for a while (0w40), but then switched to Rotella.

I just put Redline 5w-30 into my 2011 STI at the last oil change. We'll see how it goes.

and the dealership where it got changed used 5w 20 motocraft they sell ford and thing of tht nature im pretty sure its to thin and wasnt synthetic
