Royal Purple Oil...
--------------------------------------------------------------------------------
Well today I changed oil and filter in my '97 C5. (with 57,405 miles)
I'm now using Royal Purple 10w30 synthetic and K&N HP1007 oil filter.
In the past I have used Mobil1 and Castrol synthetic oils.
The reasons I went to it is because it claims a HP and torque gain and oil change intervials are 12K miles. Recommending changing oil filter 3k to 4k and top off with the Royal Purple oil.
So with the use of Royal Purple oil; what can I exspect to see with it's usage?

My 96 LT4 saw a 5hp gain from changing to Royal Purple in engine and diff and Castrol in ZF trans. My 02 Z06 was just changed over to RP in engine, trans and diff - saw a 3hp gain. Actual dyno results, before/after. I'm sold on the stuff!
