I just skimmed over the UOA section, there were maybe five OCI's of 10k or more using synthetic on the first 3 pages of that forum.
Also, why is it that the extended OCI oils, like M1 EP, have a waiver that under certain driving conditions the user should follow the manufacturer's OCI recommendation, which is usually 5k?
Why is it, that under the same conditions, dino recommendation is not reduced, it is still 5k, regardless of oil used?
Where are those blanket statements coming from?
People should use whatever they want, I'm not trying to change anybody's choice here, but what I am trying to do is stop the spreading of blanket statements and marketing [censored] that is so rampant here and passed along with no challenge.
We used to ask people for their driving conditions, seasonal temps, car make, engine type, sump size, mileage, etc. before making suggestions. Few of the older posters still do, but that is not enough
+2 Very well said!
I'd be willing to bet some big money if I did extended drains following all the fine print, disclaimers, etc. I'd have problems with my vehicles. Following blanket statements and extended drains are not for everyone. Come to think of it, it would have to be some big money to cover the cost of the repairs. LOl
I don't think it's very well said at all. My long experience with 10K OCIs in many differant engines, and all of those I know doing 10K OCIs and longer(some up to 20K) with engines ranging from 2.0 diesels to Chev and Ford V8 to MBs, Jeeps, Hondas and many others, all have never had a problem with long OCIs. There are the few exceptions, but they are very few.
