Maybe. I've sold thousands of EaO. Haven't heard of a bad one yet. Besides, if I have to buy and install 20 PureONE filters instead of 4 AMSOIL EaO's, that alone writes them off my list.quote:Originally posted by ADFD1:
I wouldn't write the P1 filter off just yet. P1 vs. EaO filters, my guess is for every EaO filter sold Purolator probably sells 1,000 filters. My point is a bad filter could have gotten by. I'm sure there are bad EaO filters too.
The only issue AMSOIL has is they recommend following the new required oil filter change intervals to be covered under the Toyota extended warranty for the sludge prone engines, instead of the 25,000 mile/1 year recommendation. AMSOIL recommends the Mann filter for up to 7500 miles to save the consumer money and to meet the new Toyota oil filter change interval warranty requirements.quote:As a side bar- Amsoil had issues with the EaO on Toyota vehicles.
