BTW i was searching a Royal Purple Any Good Topic due to the fact i was going to switch to it,on google and found that on a mitsubishi fourm a guy stated this:


There is relatively little factual information regarding royal purple as far as VOA's and UOA's are concerned. For one, Royal purple tends to have higher levels of lead in it as a friction reducer. Bad for cats, doesnt always meet the latest oil requirements, however I am not sure which they are up to at the moment. Also, royal purple will have a lower viscosity. Now the viscosity and weight of the oil are independent of each other. For example, motor oil can be rated as Xw30, assuming under the 30w conditions, the viscosity is between 9.3 and 12.5 cst (centistokes). In the lubrication world, this is a big difference. Royal purple's synthetic viscosity at 100*c (a typical standard of operating temperature, along with 40*c) is thinner than several other oils, which is what allows less drag. Comparing 10w30, Mobil1, Amsoil 7500, Castrol syntec, Pennzoil Platinum, Pennzoil CONVENTIONAL, Valvoline MAX Life, and Conventional Castrol GTX are all equal or less viscous than Royal Purple. A lot of it is marketing, Amsoil 7500 is regarded as an excellent oil. There are racing oils which outperform these oils however can damage cats and typically are not recommended for street driving due to a lack of additives.

It was discussed in Castrol Edge?? thread. For in-depth oil information I like Bobistheoilguy.

No prob. For some reason, I could not get the search engine to pull up Castrol Edge, either. Had to go back and find it manually from memory.
