Planning first oil change @ 500 or 1000mi - Toyota Yaris Forums

TheSilkySmooth · 04-16-2009, 05:54 PM

I would leave the oil in at least 1500mi. It is good oil. You will have a hard time beating it. Mobil clean 5000 5-30 is near factory in operation. I have had MAJOR problems with the toyota 90915-yzzf2 filter causing chain and tappet noise and poor operation. Its NOT the filter that came on the car. I Just did my 20k mi oc and had a yzzf2 left over from a batch I bought in Dec. Used it for a few days and had to take it off . Car was not running correct. Chain noise, tappet noise + loss of power. Put on a Hastings and all was good. IDK whats up with these Thailand made Denso filters. Definitely a bad batch out there. I am a Master Engine Tech w/ NIASE cert. used to do a lot of FIAT race tuning on the 70's + 80's. HAd to beat those Datsun 510's!
