i have a 2007 mazda turbo with direct injection and have run a search to find only 2 uoa's. they were both from the same member and both had fuel dilution. 1 had 4400 miles on the oil with a 2% dilution and the other one only 1800 miles with a trace amount. the reason i am concerned with the dilution issue is because of threads from a mazda forum that ive seen about strong fuel smell from the oil dipstick. i then went to my own vehicle to find the same strong odor. just wondering if you would shorten your oci's due to fuel dillution. im too cheap to do an analysis but according to my nostril and adding the other mazda members detection of the fuel odor and the 2 analysis that ive seen this is enough data for me to be concerned......concerned turbo mazda owner
