I use purple 10-30 myself. my tuner recommends nothing less. i'm switching to AMSOIL sometime here soon though. royal purple is bad about causing leaks if you try to switch back to conventional though, as are most synthetics.

Pennzoil Platnum and Valvoline Synpower both give really good used oil anyalsis. Mobil 1 is good but is a little higher. Wal-Mart has good prices on these.
There have been tales about Royal Purple, but with the thousands of people using it, I have seen no law-suits or heard of any engine failures. You your self have used it two years with no problems.
Good post on Royal purple.

There were many old tales about Pennzoil that won't go away....like Pennzoil was paraffin based and would sludge up an engine...
Most mineral oils today are paraffin based, this is not candle wax. as some people like to think.
The word paraffin is a very common and basic term for base mineral oil. The MSDS sheets for many motor oils use the word paraffin to describe the main oil ingredient...as in "SOLVENT-DEWAXED HEAVY PARAFFINIC PETROLEUM," which is how Valvoline phrases it in their MSDS sheets.
Paraffin is the proper organic chemistry word for aliphatic hydrocarbons...more commonly known as oil. It is also the correct name for wax and candles. But there is as much difference between paraffin wax and paraffin oil as there is between a chestnut horse and a horse chestnut. They just ain't the same thing. Don't matter whether you're talking about Pennzoil, Castrol, Valvoline or your wife's Christmas candles. If you like Pennzoil, use it worry free. Hope this helps.

Also you can switch between conventional and synthetic with out issues. There are people over on http://www.bobistheoilguy.com who do it two or three times a year without issues.
API says that all oils must be compatible with each other and can be mixed, whether conventional or synthetic.
If switching between them was a problem synthetic blend, a mixture of conventional and synthetic in the same bottle would cause a problem.

Amsoil is a good oil but....
Something to ponder...Amsoil is a small company with only blending facilities, they don't have refineries to produce synthetic base stock oils.. Who do they buy these pao base stock oils from???
Their major supplier of PAO base stock is Exxon/Mobil, the largest producer of synthetic oils in the world. They purchase some Group III base stocks from Shell, Petro Canada, and others. About 90% of their additive packages come from Lubrizoil.

****, sometimes its hard to believe good or bad about royal purple. I don't wanna them to rip my truck off. So far in 2 yrs straight had no problem. I always follow oil cap weight 5w-30 so I used since with royal purple. No leak bor anything. I'm going do some search about royal purple if they not worth. I probably switch to mobile 1 with full sythenic. What about Asmoil? I know asmoil hard to find. It not many stores that sell those oils. Expect online can do that. Royal purple and any kind of oils mostly avaiable in stores.

I'm not an Amsoil fan. I don't care for their multi level marketing and some of their adds push the limits on honesty.... The first to invent synthetics....
