H22toF20

Over 3 years of browsing forums and I've seen countless H22's experience excessive rocker wear with many oils, both dyno and synthetic. I've seen zero H22's have rocker wear, while using Royal Purple and haven't experienced any with mine. Alot of people have actually made the switch due to this. The theory is that the diminishing Zinc content in modern oil is the soul purpose of this issue; Royal Purple is high in Zinc. Royal Purple is actually not a true synthetic anyways, it's a synthetic blend.

I'm not saying that Royal Purple is the mother of all oil's, but to say it's crap is far from true. Then you bring marketing into the mix, yet you link us with a link from Amsoils site. It's not 3rd party if they had the test done. I'm not saying that Amsoils bad, just that you should look for a real independent test before you draw some conclusions. It's like the merical 20hp gain from intakes, that every company states.

Curious as to why your using 5/40 the 10/30 ATM is by far superior to the 5/40 AFL. Look at the TBN and the noack ratings. I used the 5/40 for a bit when one of the Amsoil gurus pointed this out to me as well. I took advice elsewhere rather than researching myself, I got lazy. You may want to look at the 10/30 ATM if you want the best Amsoil has to offer.

i used to run RP for years in my car until i found out its all hype. i dont remeber where i read it but it had dyno graphs and all

Dyno graphs? That could possible the worst test for a Motor Oil Ever...hah

B serious

Woah! Your $8/qt oil is smooth after 1500 miles?

I chose to run it as my first fill since getting the car in the fall months, haven't put more than 600 miles on it yet. I want to run it for one oil change interval and see how it holds up. I'll probably only put about 5000 miles on it a year, so long drains and high TBN don't matter much as I'll change it once a year regardless. Personally I chose it as I like the viscosity number of this oil, it's a thin 40 weight, so it might shear down to a thick 30 weight, possibly over one OCI. I was considering their ATM 10w30 as it does have better NOACK and wear scar number (for whatever that is worth), but that would be my second choice if this oil doesn't work as well as I want it to. My car was also running very rich when I got it, so I felt more comfortable with the 5w40 viscosity to handle possible dilution. I think that I've fixed the problem since then though.

I gotta say that running the 5w40 makes my engine eerily quiet, it sounds like fine watch, and the engine feels very smooth, I like how it feels. I haven't noticed any performance loss or mpg loss, though I understand that it could be happening, it just isn't noticeable. I also haven't burned a drop of oil in 600 miles, so far so good. I started the car and drove it about one day a month over the winter season, the 5w40 worked well on cold starts despite frigid temps. I'll have the oil analyzed and go from there. The car had Syntec 10w30 in it when I got the car, I prefer the way the car runs and feels with Amsoil 5w40, I'd go out on a limb and say the car feels stronger running Amsoil 5w40 over Castrol 10w30, but that's just my impression, no hard facts. Either way I like it. It's a recommended viscosity from Honda so no worries on my part, I'm also a bit old school about having a bit thicker viscosity for high revving motors. I'll see how it goes, thanks for the recommendation.
