    Pennzoil synthetic

    Anyone have experience w/ the pennzoil synthetic in the WRX or any other car for that matter? Just changed @ 5800 for the 6000 mile "dealer suggested" service, and saw a significant price difference (Penn. 3.50/qt., Mobil 1 5.50/qt.). Any help is appreciated.

    When restoring my first "ride", a 71 Ford Torino, I used cut up beer cans as backer for bondo. Theory was, aluminum wouldn't rust, so why not?

    Pennzoil synthetic is not worst the price. The regular Pennzoil are better for the price you pay for it. There is a reason why Mobil 1 cost more. Itís a group 4 oil and Pennzoil is a group 3 oil (inferior grade).

    Have you considered Amsoil synthetics?

    It is hydrocracked, just like the Castrol! Not as good as Mobil1!

    but if you look at Amsoil's advertisement, for the 4 ball bearing test (something Amsoil highly touts), Castrol Syntec outperforms Mobil 1 Tri-synthetic.

    Tan posted a link before about Pennzoil Synthetic that showed it is an outstanding synthetic motor oil.

    On the same graph they show regular Pennzoil to be the next best oil after Amsoil 2000.

    I have used both Pennzoil and Mobil 1 synthetic in my WRX. I personally have found that mobil 1 is far superior than Pennzoil. I noticed that my fuel concumption is better with mobile 1. About 20% better overall. Fuel consumption is the only measure I use.

    Hope this helps.

    Thanks Trex

    From what I've been reading, I've gotten the idea than Pennzoil synth may not be the best for my car, I'll be changing it out at 3000 miles for either the Amsoil or Mobil 1. Thanks for the feedback everyone...
