Always enjoy the oil threads. -Here a cut & paste of a post I made back in '06 about Brad Penn.
I'll share my experiences with Brad Penn oil.
Up until last summer (2005) I had been running Pennzoil 20-50 (engine builders recommendation) I change my oil every 10 hrs and it seemed to work pretty well, no oil pressure issues, oil temps @230 after an occasional hard run 260 (measured before the cooler)
Toward the end of last season I had switched to Brad Penn 20-50 and was not very impressed to say the least. In June I trailered over to Lake Winnipesaukee for Laconia weekend.I had just done a fresh oil change for the trip. We did a lot of boating the first couple days. After three days of running Brad Penn (8 hrs run time) I noticed a loss of oil pressure. My boat normally runs about 60 lbs after warm up while cruising. We were cruising along at no more than 4000 rpm when I noticed the oil pressure dropping. It dropped to 40 lbs, then 30 lbs, I backed down to 3500 and pressure dropped to 20 lbs.
I thought It was engine trouble and stopped for a while. Upon restart, oil pressure returned to normal, 60 psi but soon dropped back to 20 after temps warmed up to normal.
It appears that the Brad Penn oil was all done at 8 hrs and was breaking down at less than 220 degrees oil temp.
I've since changed to Mobil 1 (V-Twin) and all has been fine since. The Mobil oil seems to be pretty consistent, no pressure fluctuations at all and more oil pressure.
Take it for what it's worth, just my personal experience.

I do get it and don't want to argue. The 2 links you mentioned originally were more definitions than anything else. John Martin spent most of his time with Lubrizol. Lubrizol supplies the bulk of the oil companies with their add pack. I'm sure he's way smarter than we are. But he doesn't talk about a specific oil brands. This last article that list the 14 oils truthfully is tough to completely understand. One thing I did note though was that he said he only had 47 oils in his data base. I may be wrong, but I think there are more than 47 oils out there. So, his "winner" is just that. HIS WINNER.

Your kidding right? The point is the outcome he has listed is incomplete and totally misleading. I don't care which oil you choose. Let's say Mobil 1 for the sake of conversation. Let's assume he chose one part number (because that is what he has in his data base!!!!) and perhaps it only came up to his definition of modest. A bunch of people on this thread now go "gee I'm surprised at how poorly Mobil 1 did". How is that right/fair to Mobil 1 who perhaps has many other part numbers that may have come up to outstanding, or whatever the term they used as the top performer. Not to mention I don't even know what his data means. Is this data a recognized method used by the industry. I don't know, do you?

As posted earlier I have run Brad Penn with only ok results. Same type of situation where there were oil pressure issues much earlier than I expected. . Amsoil , Mobil 1 and Valvoline Racing are three more that I have personally had good luck with. I have and still do run Venom Semi synthetic and have had very good luck so far. Got the Venom info from a tractor pulling friend of mine and it has been great and is priced reasonably. Just my 2 cents no oil guru here just sharing what has worked for me and my customers.

Obviously the key is maintainance over brand. Whether x oil tests at 60,000PSI, or Y tests at 100,000psi, how do we know 60,000 isn't plenty for what we do? I don't know the answer to that. But, next time im shopping for oil, and the oil that sustained the 60,000psi, is next to the oil that sustained 100,000psi, and they are the same price, I'm gonna grab the one that tested better, vs the color of the quart or the label that's on it. The test I posted did not appear to be one of those infomercials trying to promote a certain product. There seemed to be enough data to rule out BS claims and biased opinion.
I guess my whole point to this thread, was theres more to oil than how much "zddp" is in it. Because that's about all everyone ever talks about, or looks at, in their basis on whether or not its a "good'' oil.
Let me ask you Ben, since I and several others have tried to contribute and share some useful information amongst each other,
What oil do you run and recommend?

Ok, man if that is how you feel. I was not trying to argue or be negative. As I said above I just felt that it was misleading to all the oil companies to be honest. You and I both know there will never be total agreement on the subject of oil. Truthfully all the name brands are going to do the job for you. The amount of engine failures as a direct result of an oil issue are so slight it probably isn't even worth mentioning (excluding the flat tappet issues............which argueably could be traced to other issue as well as reduced zinc. But, we certainly can't go there.). So, goodnight.

Joe, don't waste your time. Your input on this topic I can guarantee you made a lot of people think "no shxx, I didn't know that!" And that's the purpose of these threads! I truly wish if people didn't like a thread they would save everyone's time and just not even read it. Bring me solutions, not excuses and stupidity!!! Thanks again.
On topic, a lot of people really like Royal Purple and AMS oils. Were they in the tests or did I miss it. Just curious and thanks again.
