I'm not sure about that. I think that you would be more correct if you said: "The multitude of UAO's that have never gone to 7500 because the owners have never waited to get a 7500 oil change, don't warrant a 7500 OCI".quote:
Once again the majority of UAO's don't support the 7500 change.
No, they probably didn't. Didn't you see the thread a little while ago "how do manufacturers set oil change intervals"? Fist of all, they use a standard number like 5000 for severe or 7500 for "normal" driving because that's what everybody else uses. They look at the minimum number of oil changes needed to get that engine to last 100-150,000. I don't know about you, but I'd be pretty pissed if my engine crapped out at 100-150k. They do that for both the EPA, less dirty oil going into the environment, and the consumer - the average idiot looks at that 7500 and thinks "wow, I hardly ever have to change my oil - that's how great of a new car I just bought". They don't, however, set that interval to make the engine last the longest and run it's best. Same thing is true for the new engines that call for 5w20 oils, it's not necessarily the best for the engine, but it is the best for the EPA regulations.quote:
