On the 5th of March, I changed the oil on my CVPI and used Maxlife 5W20 with Lubeguard at the recommended 3oz/quart dose.
Prior to that I was using straight Maxlife 5W20 and in the course of 14k miles I had to add 5 quarts of oil. Every 2500-2750 miles it would be due for a quart very reliably.
The first quart after the March change I had to add at 3500 miles. I didnt have to add a second one before I changed it May 9th with 7k miles on the oil. It was about 3/4 quart down when I changed it.
Since May 9th Ive put another 4k miles on the car and right now its down about 2/3 of a quart. Im thinking it will get to 6k and still not need oil at which point Ill do a sump drain and fill, leaving my Ultra on the engine.
What say you? I think I have a pretty good case since all I did was add Lubegard to the same oil I was running before. Obviously I am driving it a lot more. Before the March change, that 14k took 2 years to complete, and in the 3 months since I put 11k on it.
But, the car doesn't leak on the ground. So its not losing oil just sitting there. My biggest external leak is the valve covers, which I would think would mostly leak while the engine was running.
