I'd have to agree that PureOne is a better deal than an EaO in a priceerformance ratio. EaO's were specifically designed to go one year and up to the limits of the new SSO. This will typically fall into 15k or less for most people. Beyond that point, loading isn't a mileage weighted issue since most loading occurs during start up with the combustion byproducts of fuel enrichment.
The test on BITOG is interesting where the M1 filter beat the EaO in 5k pore blockage particle counts. I'm waiting for the 10k figures of like comparison. I think that we'll see the gap closing as the mileage markers increase, at least I hope so. Even significant movement toward parity would suggest that a 15k test would be even better ..and one could speculate that the EaO would still be filtering well when the M1 was approaching saturation.
PureOne is what I would recommend for anyone above 12k/year. I'd probably recommend that even if they used an oil that they only ran for 6months.
