My MazdaSpeed 6 is a direct injection motor. As seen by the numerous UOA's on this engine (Speed6, Speed3, CX-7), the oil seems to thin out by quite a bit during even a 3,000-4,000 mile interval.
Here is my last UOA. As you can see, there was only a trace amount of fuel detected in the two samples. Wear numbers weren't bad over the 4,300 mile interval. Because of that, I haven't been too worried about the dilution.
I've recently started taking much shorter trips with the car. These trips are in town and usually less than 5 miles. Because of this, I think my dilution numbers may be higher. I have used LC20 in the past, but that bottled was used up a few months ago.
I'm wondering if any of the current oil additives out there can help combat thinning of the oil due to fuel dilution? I have a couple bottles of Auto-RX still around (3-4 years old) that I could use, but I thought it was good for engine cleaning.
Anyone have any ideas? Is this just something I have to deal with by using shorter OCI's? I always use a quality oil such as Mobil 1 and PP is in stock right now in my garage.
