Haha, I am running 0W-40 now and will likely be switching to Rotella 5W-40 so I can make my excessive oil changing habits more cost effective.

The only issue I have to date is that my used oil analysis are showing a lot of fuel in the oil but I only have 10k on the motor so I am considering replacing my injectors soon and fuel pump.

 

exactly- the 25% thing was made up out of the ether by someone.

last i checked it was somewhere around 5%-7%. that was a real number from real people involved within mazda. it might have climbed to 10% but anyone saying more than that would have to provide some proof other than web polls.

remember Im the guy that actually put that video (talked about in the article linked earlier) out there for you all and a friend of mine nearly got burned for it.
