There are any number of things and if I were to implement:
1. pre oilers
2. bypass oil filters
lastly and a huge structural change: dry sump.
Obviously the thing to ask is what one is trying to achieve by going to the next step in lubrication. #'s one and two's logic goes something like this.
At an aftermarket cost of app 400 dollars (oem costs would be substantially less of course), preoilers provide pressurized oil on/to the moving parts which will otherwise rub against each other normally UNLUBRICATED causing up to 80% of the wear over time. They also can provide "emergency" pressurized oil when fuel starvation conditions occur. So given 80% less wear due to cold start up one can extend the OCI. To further aid in extention and even better cleaniness a bypass oil filter will further filter smaller particles not filtered by the standard filter. So for example 20,000-40,000 mile ocis can be gotten of course with analyisis if one is at all in doubt. So if you keep the car as a normal driver would 8 years and do between 12-15k a yearor 96,000-120k at one level does this make economic sense? In other words over the course of the mileage and time you would change your oil 3 to 5 times vs a more normal 32-40 times.
