what grade oil??
Hi - 2002 V70 2.4 petrol - close to 160,000miles
I've always used Castrol fully synthetic 0/30 oil but wondering if something a bit heavier now - say Castrol 10/40 Any thoughts? Thanks Kevin |

I'm at 145k , always used 0W30 and plan to continue. If I understand the logic the heavier oil is to plug the gaps in a wearing motor and restore compression. You'd need to measure before and after to see what if any benefits resulted.
For me the downside of 10W40 is longer time to reach top of motor on startup, more heat generated and the farther the two numbers are apart the more it has been tricked with and the less time it stays in grade. Will it actually matter ? Probably not. |
