I just bought a 3.2 TL with just over 300k on the original engine. The previous owner told me that using any oil filter other than the oem type can damage the engine and that only 20 w50 in summer and 10 w40 in winter should be used even though the manual recommends 5 w30. Anyone have input on this?

 

Just stick with 5w30

You'll just waste more gas with 10w

 

nobody should use 20-50 on anything for the street ever. ken is right on thought i think, i run 5-30 all year with 208k,mi

 

do 5w 30 in the winter and 10w 30 in summer. if he used 20w 50 it's maybe because the engine is going bad.

 

yeah but thats the wrong theory. thicker oil makes it harder to get into certain clearances within the motor. you can do the 10-30 thing but i really would just stay with the 5-30 myself

 

I remember when my car starting to smoke a little bit, people told me to go with thicker oil and that will take care of it.

 

5W30 all the way.

 

I'd use a good quality off the shelf oil filter as well as the 5/30
