I use Delvac MX 15W40 in my IDI and Powerstroke. The IDI did consume some oil too before that (whatever the preowner used?) and after I changed to Delvac no oil needed to be added between oil changes. Same with the Powerstroke which is do for an oil change now (almost 5000mls reached).

What is the mx? I got Delvac 1300 Super 15w40.

On the factory gauge. My 91 reads perfect and it’s not connected to anything. That should tell you what you need to know.

Its probably just the engine twisting under load that pulls the wire just right. I'm still running the idiot meter in mine but would like to try the "fix" some day (replace the sensor switch with an analog sensor).
