'04 Cummins 7500 Miles on Delvac 1

[Lightman]

I just thought I'd share the results with you guys. I am very pleased with the results and it's clear to see that the oil was barely even used(yes i wasted a good bit of money ). I should also state for the record I have an Amsoil Dual Bypass setup that was installed at the time of this oil. This is also my truck's first run of synthetic oil. I previously ran Delvac 1300 before switching at 12,500 miles to Delvac 1 and installing the Bypass kit.

Oil Analyzers Inc. performed the tests.

Looks good, but isn't the OCI 15,000 miles on the '04 engines? Heck, that's with "standard" oil and no bypass...

The OCI is 7500/15000 severe/light duty. I am somewhere in between as far as use goes, and I wanted to get the oil out because it was my first run of synthetic, and 20,000 was a nice rount number

Can Delvac 1 or Truck & SUV Mobil 1 last 15,000 miles in a gas motor ???

Boeing 757 Pilot, the Delvac could last, but an oil anaylsis at oil change intervals the first time would prove its ability to go the mileage.

How do you guys like that silicon rating of 3 with a 'dirt sucker' k&n ??(AFE)
