Joe Gibbs Oil---cloggs a standard filter ???

[Marine One]

Allot of things can cause a filter to plug. On well used and abused oil, it is the obvious things like carbon. Sometimes good oil can react poorly with fuels in the combustion process to form molecular chains that kill the TBN value, which causes carbon and soot to quickly build up.

I did not see if you listed the grade of oil, but analysis labs over the past few years have discovered an issue with the bases used to formulate any brand of zero weight (0W20, 0W30, etc). The first time a zero weight is ran, waxes start to shear and collect in the filters. The colder the climate or the better the filter, the greater the chances of seeing a plugged filter.

The good news, it only happens once; the very first time the zero weight oil is ran with the kinds of heat and pressure found in an engine. That means you can keep the clean oil and just do a one time replacement of the filter after running it for a few hours. This has only been noted in zero weight oils, nothing else. If you are not operating in northern Canada during December, you probably should stay away from the zero weight oils anyway.
