During purchasing a CPO 2009 IS350 with 69K yesterday, I was informed by the dealership that they had always used Pennzoil 5W-30 for my car's oil changes. I told them I was gonna go with synthetic. They told me their mechanical "guru" said that with the 350 engine my OCI should stay at 5K no matter if I used conventional oil or synthetic. I thought it an interesting. He said I could stay at 10K on my LS. What do you think? Is that engine so tough on oil?
Also, I got the shock of my life when pulled it in the garage and heard the engine "ticking." My heart sank until I found out he ticking was from the DI and was perfectly normal. I hope this may help some on you.
