Engine oil OEM Subaru or Motorcraft
I run 10w30 motorcraft because my 300 doesn't dry start as bad with it
They sell Subaru branded Idemitsu at the parts counter
Só compro óleo original na concessionária e da Motorcraft conforme manual.
switch to 5w20 as according to fords bulletin for oil, i been using motorcraft synthetic blend for 26 yrs
'17 f150 5.0l with 150k running 5w-20 motorcraft. Not a single problem and this was used to haul a 12' steel enclosed trailer loaded from day 1 and the wind blows a LOT here. Doesnt use a drop of oil.
Oil being dark is a good indicator that you have to do an oil change. However, you shouldn't wait until it changes color to do it. Clear oil doesn't necessarily mean you can keep going.
It is well established that boxer engines want their oil changed and I do not think for a second that a visual inspection is valid for determining if it is time. Highly, **highly** recommend you change the oil per the manual without hesitation and regardless of what it looks like.
I run motorcraft in my mustang and have zero complaints.
0w20 provides your engine with more wear protection .
There is minimal difference between 0w16 and 0w20, with 0w20 provided marginally better wear protection and 0w16 providing slightly better fuel efficiency since it's slightly thinner and provides less internal resistance.
I have a slow oil leak (something like a quart every 1,500 miles). Dealer quoted just under $3,000 for the fix when it was 17 years old with 110,000 miles. I'll just buy the occasional quart of oil.
