I'm just trying to justify the money that people spend on this stuff, it's a little unbelievable. And I won't get into the OIC's, that's just being wreckless with the environment at a time when we need to save precious resources.
Europeans have been on insanely long intervals forever, and now finally in America does Mobil claim 15k on their top synthetic (too bad you can do it on conventional too).
So, you aren't racing at redline all day, and your engine will outlast the frame.
What's this all for?
Definitely not trying to flame anyone, just curious what the rationale is.
Pennzoil 5w30 conventional is good for 15k miles, by the way. Ran civic on that for hundreds of thousands of miles. UOA? PFFT.
For someone not trying to flame anyone, your post is pretty provocative. But point by point:
1. You really don't need to justify how I spend my money. Nor do I need to justify it to you.
2. I doubt my OCIs and the 3.6L sump they come out of have much of a relative impact on the environment. Particularly since the oil gets recycled.
3. Whether you can do 15k on conventional or not, isn't the same as 15k being optimal.
4. You assert that you ran your Civic on Pennzoil conventional for 15k OCIs for hundreds of thousands of miles. Then you later admit you did this once. There is something seriously wrong with your math.
Too many blanket statements. And you base this on your unique experience of doing this for 'hundreds of thousands of miles'. Then later admit you did it once. The platform you're shouting from is looking pretty shaky from here. I've seen sturdier ones built from cards.
