Here is one conclusion:

If I were to purchase a new 2010 Mercury Grand Marquis and I wanted to be able to load it up with people, gear, and tow a boat, I would add a tranny cooler, break it in with RP break in oil, and run RP 5W-20 with 5K OCI.

And I would not think of using M1 in it.

We here at BITOG are always going to need a "punching bag oil". I think in many repsects RP has earned its bad reputation here. False advertising and issues with shearing just to name a few. There are still many variables to consider here. As the OP mentioned, he is unsure of the other mustang owners attention to maintenance and if it was run low on oil.

It would be funny to see more interest in RP here. It happened with Redline. People were so caught up in UOA's being the gospel....blah blah.. But Redline is a much more popular oil in the raing communities and for good reason. I believe it to be superior to RP after using it for many years in various apps and seeing others in the camaro circles try RP with unfavorable results. To each his own. For this application and OCI RP seems to be doing very well. There are many good oils. Nothing better than tear downs to evaluate what is working even if it is brought about for different reasons than oil selection.

OP- Are you planning on pulling out your micrometer and recording some actual data. Pics look good, dont get me wrong, but the proof is in the measurements. I like this stuff!

And why is that? I rank the Royal Purple right up there with other top Synthetics like Amsoil, Redline and Motul.
I do not understand why it's so hated.. Maybe the Color? For some it's the Bad Marketing claims, for others it's the couple of UOA. It's like with me, I know Amsoil is a good product, I do not like the MLM scheme. If the product is so good, allow it to be sold at autoparts stores. JMO ...

I am planning on it. I want to document it correctly with pictures of each mesurement. Coming soon....
I also ordered the kit from blackstone for the UOA, that should also show some more info. I will have my friend do one too. BTW he still Loves M1.. he says the wear is minimal for him to worry about...

Amsoil ..M1 .. you name it. Slammed mercilessly. Heck, it's not just motor oils either. grin


I'll wait to see the micrometer readings. Even that will not vilify or vindicate/fortify anything. Pull out a cam from a taxi with 250k and see what that shows and you'll probably have more of a good bearing on what THAT cam saw then what we know of the M1 cam in the images.

I have nothing against RP, I made a comment, that it's a punching bag here. I don't use it, and I'm not a fan of it. I'd be interested in seeing the measurements as well. Truth is if there were only 2 oils to choose from, RP and M1, for that application, and pictures were the only thing to go by, the M1 would be sitting in the store collecting dust.

RIGHT NOW, RP is the punching bag. Not long ago it was Castrol. Tomorrow, who knows.

We get a lot of opinion here and what I've learned is that you don't get between a man and his oil... whatever brand. The vitriol that sometimes comes is hard to understand, but observing it has made me much less brand conscious. Maybe that's the hidden purpose of forums like this. Glad to see this thread got back on track after some rough water.

Obligatory Topical Content: I've been running RP for tests in a Ford 5.4L 3V modular, with one good UOA so far. I have about 9K on 5W20 so far (one 7.5K, 18 month run and the next will likely be 2 years and 8-9K) and have enough oil for at least one more change, which will take the truck out to about 26K, or so. Hopefully I won't have to tear the engine down to make any points in this argument! Those cam pics are very telling, though somewhat anecdotal being only a single instance.

RP is a punching bag, I've never used it, but might consider it. They say a picture is worth 1000 words, RP did better than Mobil 1 in the photos, enough said. If I was asked to make a prediction of what oil is going to be The Bitog Pin Up Oil Darling For 2010, my guess would be Castrol Edge. Lousy marketing and all. JMO. I'm anxious to see measurements too.

I don't about the lousy Marketing, I kinda like the Scotish guy wipping people with a dip stick....
Funny...

I can't help but feel like if you looked at a pic of a guy with a black eye, and heard he had steak for lunch, you'd say "the steak gave him a black eye in the photos, enough said..."

Interesting comment, those pictures didn't look like RP held up better to you?

There is not enough information to make that call either way.

I think that point is KEY.

I guess we see things differently which is OK. I looked at pictures and the info given, since that is all I had. I based a decision on that:


2007 Mustang GT [40,000 miles] OCI 4000-5000 miles
Mobil 1 5w20

2005 Mustang GT [70000 miles] RP OCI 5000-6000 miles.

Based on that and that alone to me the RP did better. Now we could say the 07 was beaten, had a bad cam, and go on and on. I went by what I say and what was written. As a side note the 2005 was driven 30000 more miles and had a longer OCI. Opinions vary, and its all good.

This guy had steak for lunch.

Obviously the steak gave him the black eye.

Man has black eye
Man had steak for lunch

Based on that and that alone to me the steak gave him the black eye. Now we could say that he got in a fight, had an accident on the job, and go on and on. I went by what I say and what was written. Opinions vary, and it's all good.
