slick 50 and RP are hardly the same. for the last 10k miles my car DOES run better and run smoother than it ever did on moble 1. i think im am going to try reline for my next oil change though, but not because i am at displeased with RP.

and as far as RP "raced backed support" maybe you missed this:

like i said, oil is almost like religion, everyone believes something different is best, and sometimes its best to leave it alone.

 

on TV, speed channel. I can't recall exactly which show it was, but i'm thinking big block.

Supposedly it was back to back and they might have used RP, I only caught the end.

 

I know folks that have used standard Pensoil, Citgo, Quaker State, Texaco and any other number of oils off the shelf for endless miles and never had a problem. That's not the point here. The point is to choose the highest quality synthetic.
Mobil 1 is not the best synthetic - not by a long shot. And neither is Royal Purple.

The ONLY advantage standard Mobil 1 has over conventional oil is it stays fluid at cold temperatures, where conventional oils turn to gel. That's pretty much it.
So why would you spend the extra money on it? Because they tell you it's worth it - and you're not willing to research the facts that will ultimately tell you that you've wasted your money for all those years (kind of hurts the ego).
Here you go - it's not worth the extra money you've spent. I'm being honest. Do a little research and spend those dollars on a much better synthetic - Amsoil or Redline. Or if you're dead set on a Mobil 1 product - spend the extra money and buy the Mobil 1 EP. It's a decent synthetic oil. Not as good as Amsoil, but a much better oil than standard Mobil 1.

 

You post is full of generalizations and lacks specifics.
Additionally, you can say the same about Mobil 1 and Lucas Oil - most of that is marketing and sponsorship and has nothing to do with products produced for the streets.

Here's the hard facts:
The oils you use and the oils used on the race track are NOT the same.
Standard Mobil 1 is nothing to write home about and really doesn't outperform dino oil. Yet Formula 1 racecars use it right?
NO. Sponsored race teams use custom high quality formulations that are as unique and expensive as the race parts used in their construction. It's like saying the WRX STi you can buy at your dealership is the same as the cars you see in the WRC. There's about a $200,000 difference in price tag - and there's a reason for it.

Royal Purple spends too much time sponsoring teams so you'll get excited buying it. Unfortunately, you're not buying the same stuff the race cars are using.

 

and I totally agree with you!

 

Slipstream444,

I've always used Mobil 1 synthentic because I've alway been too lazy to research another product(I simply bought the hype). I used it in my '02, and the motor had to be replaced. I'm not saying the oil was at fault, but it was possible it had a hand in it. I believe there was an issue from the factory with the cylinder wall scoring at 30,000 or so miles.

Anyway, my question would be: I just bought an '07 new. Should I replace the oil at 5,000 miles with Amsoil 10W30 full synthentic? When and with what should my change be?

Thanks for the input.

Hmmm...

Thank you for you knowledge. Are you saying that you don't think it's necessary to switch to a semi-synthetic after the first 750 miles? I was planning on running the factory supplied oil that came in the car for about 3000 miles and then make a direct change over to Amsoil, I'm guessinng, 5W30. I live in Orlando where it doesn't break 95 degrees.
