I do feel that his insinuated comparison with his over-sized sump 13k OCI BMW, which takes top tier A3/ B4 synthetic vs. my 5k dino Jeep was an apples to orange comparison. Telling a dino user that they are "anti extended OCI" while running a top tier A3/ B4 synthetic makes zero sense to me.
If you look at this thread, most folks that are pro 3x OCI'ing a filter run synthetic so at this point, explaining your thoughts with them is absolutely pointless.
You misunderstood the comparison entirely.
The point is that 3 OCI's at 15k miles and one OCI at 15k miles is the same filter experience.
A person says "I'm scared to death of running a filter for 15k miles" is in fact scared of an extended OCI, because doing an extended OCI involves the extended use of the filter.
My comparison addresses only to the people who have expressed anxiety over extended FCI's as a means of attacking those who do multiple OCI's.
And for the record, I did 19k miles, 2 OCI's using dino oil on a single Fram XG2 on a vehicles with well over 100k miles, 5.4 liters of displacement with a 6 quart sump. UOA's were better than that of many 5.4 3V trucks on a single filter, synthetic, and a 6500 mile OCI.
It has nothing at all to do with the oil being used, and everything to do with people attacking multiple OCI's on a single filter by making up a "problem" that millions of cars live with a daily basis. There is absolutely nothing abnormal, risky, dangerous, negligent, or foolhardy about running a filter for mileage around 15k.
I can't imagine what the filter-fear crew would do if they had to drive a commercial truck, where they have to dirty their drawers everyday watching the same filter on the engine for 20-35k miles.
