I work as a tractor and grounds equipment mechanic. I have now for 31 years, at the local school board. We only use Fram oil filters. I have never seen an oil filter related damaged engine in all of this time. However, because of this write up, I'll never again use one on my personal vehicles. Thanks.
I have seen several that were assembled so hastily that the ends of the filter element was not attached.
Now they have designer filters to create a "premium purchasing experience" by getting people to think that a high mileage or synthetic oil engine needs a different filter.
Fram banks on the fact that oil contaminants slowly wear out engines in a manner that is essentially impossible to quantify on a small sample basis. How many engines that Fram wears out early equals the loss of a complete power unit?
Basically, it comes down to the fact that frequent oil changes are a better deterrent to wear than the best filters because the change removes abrasive contaminants and corrosive chemical from the engine.
If your school board is going to support a filter, why not support one that costs the same but filters well?
Some filter brands are being made in China now, including Fram. It is nearly impossible to maintain a quality control program in a Chinese factory.
