MPTIndustries MPT27 5W/40 Hi-Performance Fully Synthetic Motor Oil - 1 Quart

I was searching for a "TRUE" full synthetic for my 2013 BOSS 302 because most oil that says: true synthetic is only about 65% synthetic. There are other brands out there that are, but I was impressed by this formulation. Since I put this in my motor with a Mobile One extended life filter, I've had better mileage and can notice an increase in performance. I also feel my motor is well protected.*UPDATE* March 2016 - I now have about 18,000 miles on this oil. So far, it's like the day I put it in. So far, I've used less than one quart, to top off the oil level. I "do" need to change the Mobile one extended life filter though.... : )
