That why I keep tell use 5w20 or they be spun bearing or kill cam phaser that make tick noise.

if it burn lot oil then upgrade to 5w30 then stay until it really worn out then rebuilt it.

10w40 oil would cause mpg decrease almost 2 mpg and they don't lubrication great in winter. Think like ice cream it hard but when it warm it moving.

Think cold THICK oil 10w40 or 20w50 in winter that don't moving like thin oil in DOHC engine= destroy FAST result cost $5000 for new engine at dealership.

like 1 thread about grand marquis that I ask what oil it been use 10w40 I know it already bad why if I get then try put thin oil then later engine have bad bearing from thick oil.

I apart 1 5.4L to find why it threw rod. all bearings were toast. Found that owner use 10w40 dino with fram oil filter. To say bearing look really bad it chew.
