A lot of people seem to be getting in the usual forum pissing match of this or that is best.
doesn't take much common sense in automotive to know that there isn't a best that suits everyones needs, or what they do with the car. many good brands mentioned, but not gonna work for everyones wallet or driving style. lets be real here.
with that being said, I use whats worked for me, and 244,033 miles in my 07 charger I traded in on my 13 Camaro. So far in the 1st year I've had it, ive done over 40,000 miles. and half way through my second year, im already at 13,000 miles for year #2. i'll definitely hit 100,000 miles this year.
Quantum Blue Custom blended oil. and I've run an oil analysis after each change over the years.
this was the oil change back in may with 13,500 miles. has a full picture readout sheet of what was in the oil after analysis.

and I just recently did the oil change last week, and they received the sample on this Monday the 26th, so I should have those results by next Monday if not sooner, which was a 17,348.6 mile interval. Good or bad, I have no problem posting the results.
