Anyone use engine oil 5w-40 or 5w-50?

Mechanic told that 5w-40 will be a little better for old engine with a 180 000 km. is that true?

STOPPPPPP dont use any oil other than the recommended by manufacturer .
I screwed a F150 with 150k for doing that due to a change in oil thickness

I would probably split the difference and go to 10w30

Stick with the 5w30 and add Lucas oil stabilizer. If using conventional oil. I only use it in the summer as it's pretty thick and not good for cold start ups. When the temp drops in the winter.

Does it make a difference if I use a 3.5L or 3.7L K&N oil filter on my H3's 3.7?
