First oil analysis on this car. I decided to go with Mobil 1 Advanced Fuel Economy 0W-30. Honda calls for 0W-20 but I refuse to put that in a car with a turbo in the Arizona heat, along with a reputation for fuel dilution. Plus this engine is also rated for use with 5W-30 in other markets. I suppose the wear metals look okay but I'm a little concerned about the Viscosity @ 100ÂºC. Mobil 1 states 10.9 and this sample came back with 8.27 at only 3,500 miles. Also the flashpoint was pretty low at 375 when Mobil states 438. Since I purchased this car brand new, the first oil change was done at 1k then every 3k afterwards. This sample I went 3500 miles as I was a little busy. I know the method that blackstone uses for fuel dilution is worthless but the fact it shows some at all with their method leads me to believe there is some dilution happening. I'll have to use a different lab to get an accurate reading though. Previously I had been using PP 5W-30 but I never sampled it. I've been torn between these two oils as they are both dexos rated for LSPI and readily available at walmart. I wanted to use LSPI compatible oils since this engine is direct injected and turbocharged although I've never read of it having LSPI issues. I will probably use PP on the next fill and continue to do 3k intervals. In fact, its already due for an oil change next week.
