Volvo V70 over 100,000 miles thicker oil needed???
hi everyone,
My 1998 Volvo 2.4 auto has 135,000 on the clock
and is using more oil than I would like. It's currently usin 5w30 fully synthetic....my question is should I be using a thicker oil as its over 100k...? has anyone used 10w40 semi synthetic with this engine to good effect?
thanks all
