    both verry good cant go wrong with either. however for the daily driver if u change your oil often u dont need those. i had an 85 firebird first car had the 305 v8 in it. . i changed the oil every 2000 miles with castrole gtx regular oil no synthetic. that motor had 180k on it when i sold it ran like a top.

    Amsoil FTW!!!
    i used to run castrol, then royal purple, and finally Amsoil in my bike and i noticed a difference in performance from RP to Amsoil, i had smoother throttle response, smoother idle, smoother shifts, and lower engine temps than with the RP and both were put in 3,000 miles within each other...i will never put anything else but Amsoil from now on....the proof is in the pudding and Amsoil has made me a believer

    Royal purple is over-hyped. You will never see a amsoil comercial. Alot of marketing goes into royal purple but testing shows that it doesn't even perform as well as mobil 1? It's overpriced and so is amsoil for that matter, but amsoil is the best performing synthetic oil. That is a fact. I use amsoil only because I get it at the same price as I could buy mobil 1. If I had to pay full price for amsoil then I think I would save the cash and buy mobil 1 synthetic with a mobil 1 filter. That's jus my 2 cents!

    I used Amsoil in my 04 Ranger and got a 2-3 MPG gain in fuel economy. I sold it to get a 05 Dakota Quad Cab (little man syndrome - V8 was calling my name...) which I sold to finally get my 08 Tacoma Double Cab. Anyway, Amsoil gets my vote.

    Testing shows no such thing.

    UOAs over at Bobs indicate that Royal Purple is not a good oil for extended drain intervals (it shears around 5k), but that for normal OCIs it is among the best oils out there for preventing actual engine wear. Wear metals are always super low.

    The theory is that harmful force goes into the oil, causing it to shear relatively quickly but preventing the wear from getting to the metal of the actual engine.

    I'll take that any day. I can afford synthetic at regular OCIs, don't need extended OCIs, and want the best wear protection out there.

    For extended drain, I agree, Amsoil or Mobil 1 preferred.

    Amsoil in the ATV 4 stroke /Sled 2 stroke, but Mobil 1 now in the truck. cheaper and about the same performance in the tests. I chickened out when I ran Amsoil in my titan to 12k, changed the filter at 10k like they say for the 25k OCI and I lost MGP - in my opinion the oil changed viscosity and thickened...and I dumped it for Mobil 1 at Wally world for 20bucks for 5qts

    The squeak from the clutch can be greased. It's more of an annoyance than anything else, but it's nice to have it quiet.
