It's too bad there isn't an oil filter that would extend oil change intervals of the expensive boutique oil, filter out all the breakin particulate on the first pass down to 2 microns, and extend the weak additive package depletion of the high dollar boutique oil.
Not to mention the UOA (used oil analysis) will come back telling you there is plenty of life left in that oil, It's as clean as when you poured it in the engine, the additive package is still good, and no need to change it.
Barring fuel contamination, or coolant contamination, you safely extend the oil life easily 3-4 times.
We all know that by pass filters have no place on classic muscle cars, and they are ugly, so no way that could work..................LMAO
396 CHEVELLE BY PASS FILTER:
The highly engineered oils aren't cheap, and even daily driver oil is inching it's way up in price. Flushing the crankcase often with fresh, high dollar oils, and using only a full flow filter that allows all the fines to keep recirculating, plus depleting the additive package rapidly, is getting fairly expensive.
Trusting a $10,000 engine to a $10 filter, you decide.
