I have researched thread and it seems as if their are multiple opinions on the subject, but let me pose the question anyway.
The car: '05 Acura TL, 163k, 4.5 qt 5w20
I have 3 qts of Red Line 5w20 and want to use up some of my partial bottles on the next oil change to make up the other 1.5 qts. What would be the lesser of two evils - Royal Purple 5w20 or Mobil 1 High Mileage 5w20 or some Mobil 1 Advanced Fuel Economy 0w20?
It's just hard for me to never use those bottles and pay $25 for 2 more qts of RL.
