I usualy have the dealer change my oil on my TL which has about 150K. I know the manual recommends 5 - 30 oil. The last couple years the dealer has been using full synthetic 0 - 20 weight oil. Any harm with that oil? They said they don't carry 5 - 30 oil and the 0 -20 is fine. Can I go back to convetional 5 - 30? Or use syntehtic 5 - 30?


Thanks

 

Yes you’ll be fine with any of those
