I decided to try it after a few people had claimed they ran it. Put just over 5k miles on the oil and got around to changing it today. My driving patterns had not changed, which is mainly light highway and city driving. First I had parked my TRX for a few days and when I started it up I got a big puff of foul smelling black smoke. I immediately shut the engine off as I was only repositioning the truck for the oil change. I decided to change the oil right where he stood. The oil was essentially sludge. The vehicle wasn't warm so I have to account for that but it was thick as molasses. The color was "burnt" which I have never experienced with oil changes in this vehicle before, again I barely tax the motor with 99% of the driving I do. I decided to switch back to Redline 0w40. Did not send of for an oil analysis so can't provide details there. The start right after changing the oil was as clean as usual. Just my experience and if anyone has thoughts of why that may have occurred with this spec oil I'd appreciate the input. Not sure why the big puff of smoke occurred which is worrisome but Im sure there is a reasonable explanation.
