6,857Km and 7 months on Petronas Syntium 7000 0W40 Cooltech (new formula) oil:
Car has a very small 3L sump. Longer run than usual, the oil was much darker. A lot of highway which pushes the engine a bit under 4000rpm.
Factory OCI is 20000Km, no TBN but I wonder if this oil could have done it...or maybe Blackstone fuel estimate is off ? It sheared quite a bit without fuel compared to previous sample with 2,5% fuel.
Filter was Purflux LS489A as usual
Compared to previous sample, this is the new "Cooltech" stuff, not sure if I should be impressed or not compared to previous formula (add pack is similar).
Replaced with Motul 300V 0W40 and Purflux LS489A filter.
