synthetic

  1. If I have synthetic oil, can I go 20k without an oil change?

    Lexus CT200h General Discussion Forum
    I noticed oil interval is 10k, makes sense for a hybrid. The recommendation is for regular oil I think. Since synthetic oil generally lasts twice as long, does that mean I can go to 15 or 20k interval?? Nal puresyn sae 0w20 synthetic oil GF-5/SN was used. Thanks
  2. Went full synthetic for the transmission

    Lexus CT200h Engine and Technical Discussion.
    Hey guys I read forum after forum and decided Toyota WS transmission fluid is not the best. I went and bought Valvoline max life synthetic ATF. I did the work myself and filled it up with the new fluid. The old fluid was solid black at 33,300 miles. I was happy with the job until I read a forum...
