    Best Full Synthetic fluids?

    Hey Guys,

    Who makes the best synthetic fluids!? Im guessing royal purple isnt as great as I once thought they were based on mixed reviews? shes ready for her next oil change and im sure there is a better full synthetic than Mobile 1 what shes been using so far.

    I use whatever synthetic is on sale. Castrol, quakerstate, or Mobil 1 and honestly I have never noticed a difference in any of my cars I have. All run the same and look the same.

    German Castrol, Redline, Amsoil are all top tier synthetics. Realy have to do oil analysis to find which your car likes best.

    Mobil 1 isn't bad. Just overpriced for what you get.
    It also wouldn't be considered FULL synthetic overseas...but it is here.
    Basestock III can be considered a full synthetic here, but it takes a Basestock IV overseas.

    I use Pennzoil Platinum in both cars. 10w-30.
