so I picked up a new to me 2011 IS250 RWD 6MT in mint condition with only 29,000kms, original owner. Doing my research on this engine, its well known for carbon buildup issues.
I noticed '06-10 models, Toyota recommended 5/10W30, and then later '11 and up the move to 0W20.
I have read a study that Group II oil, changing at a more frequent interval with the occasional high load/rpms is a good way to reduce buildup.
Just wondering your thoughts on this, if at my next change switch to a 5W30 conventional oil. The oil in it now is 0W20 TGMO.
this is my daily driver from which I plan to keep for along time, so your advice is appreciated
thanks
PS I did a search and there is not much talk on the IS250
