You’re making that specious argument for all cars based on Toyota.My brother bought a 1999 Lexus RX300 brand new in 1999. He was totally unaware about these Toyota 3.0L V6 having the high incidence of sludge issues. He changed his oil ever 3k/6 months, and that engine never had any sludge issues.
In my case, my OCI is 4k, and I'm using a cheap but decent full synthetic: Walmart SuperTech.
I'm simply making the case that changing your ok every 3k to 4k miles with the cheapest oil/filter available might just be better for the engine's longevity than changing it every 10k miles with a $90 an oil change oil.
You’ve made the argument several times, so, you’re just trolling this thread, looking to stir up controversy.
