I just purchased royal purple motor oil this will be the first time ive used it. But my car has 137000 miles on it and i was told that if i switch to that oil and havin such high milage i would blow some seals, or it just wouldnt be good for my car. An my car is the 1999 Firebird V6 3800 series 2, is this true and if so what oil would be the best instead. Does the same thing apply to transmission fluid for my car and it is an automatic with minor slippage. Thank you

The majority on here would probably run straight piss in their car before RP -- not being mean, just letting you know how this crowd feels. The fear that you have expressed is from the original synthetics which were found to cause leaks. Those oils lacked seal swelling agents that have long since been added. Best oils to run probably include Amsoil, Penzoil Platinum, and "German" Castrol (which I haven't figured out yet myself). There is a great oil thread on here somewhere that goes into some detail on oil selection.

I believe its a bull, that if you change oils you'll cause leaks.

However, there is one leak causing phenomena that can come from any sort of lubricant switch on vehicles with higher mileage. Itís been said that over time and/or a combination of improper maintenance, some motor oils can contribute to deposit build-up. Such build-ups around seals can have a secondary sealing affect when aging seals begin to lose their ability to seal. When another competing chemistry from a differing motor oilís additive package is introduced to the said higher mileage engine, the old oil deposits can begin to be removed by the new oils additive package. This in turn allows the failing seal to be exposed to the internal oil flow as designed at which point a leak can occur.
Further, this could be more of an issue with synthetic motor oils as they can have better cleansing abilities depending upon how they are formulated.
This condition could actually contribute to the myth that synthetic motor oils cause leaks when in reality it was a faulty seal to begin with and the oil was simply doing its job.
But again, as with my personal experience and witnessed by many others, the switch to synthetic is generally a non-issue.

I'm not a big fan of Royal Purple. Presently I'm running Pennzoil platinum and when that is over I'm going Amsoil. I'm already running Amsoil in my differential. My mileage is only 48k but I don't think switching to synthetic should create a problem for you. CompSyn's breakdown was pretty comprehensive. I would change it at 5k the first 2 or 3 times for it is bound to strip a lot of contamination from the inside of your engine. That is to say it should get dirty quick. And I'm not a "troll" regardless of what the ..... below me says.
Internet Troll:In Internet slang, a troll is someone who posts controversial, inflammatory, extraneous, or off-topic messages in an online community, such as an online discussion forum, chat room or blog, with the primary intent of provoking other users into an emotional response or of otherwise disrupting normal on-topic discussion. Says the "thing" that brought politics into an oil discussion. I am done, end of discussion.
