Motul 300V Ester Core 5W-30, 5K miles/8K km '99 Toyota Altezza SXE10 - 2L 3SGE Running a WIX 51394XP oil filter & WIX 46465 air filter Engine had done 156,000 km (97K mi) when I dropped this lot. This was the first time I'd run Motul & my first ever UOA. Very impressed with the TBN for a "race oil". Should I be concerned about wear metals & silicon? I did clean up some of the plastics my engine bay with a tire shine product, could that be the culprit? https://www.motul.com/system/product_des....pdf?1339171623 Previous fill was M1 5W30 & before that Castrol Edge. There's no comparison, 300V is on another level when it comes to engine performance, runs smoother, quieter, revs faster etc etc.
