I recently picked up the latest addition of "Engine Masters" and it had the results from the Engine Masters Challenge. While I was reading I checked out what oil and filters the competitors were using. I was suprised at what I found. Out of the 30 competitors 13 used various weights of Mobil 1, 12 used Royal Purple, and the remaining 5 used Lucas. Weights varied from 0w-10 to 20w-50. The winner, John Kaase used Mobil 1 15w-50 in his 404 cid stroked Cleveland small block.
The filters were a little harder to find in the pictures, and I didnt see what everyone was using, but the majority of the filters used were either Moroso Racing filters or Wix/NAPA Gold. A couple of Motorcraft filters were sprinkled in and I did see 1 Fram Racing filter.
I think that I was most suprised by the number of competitors that were using the lighter weights of Mobil 1 without the high levels of Z & P (I guess they could have been using an additive?) with their high spring pressure solid rollers and the fact that some heavier oils were being used even though the competition is about making the most, average power. Just thought I'd share.
