So who here has used the good ole Royal Purple?

I took my car into my auto class today and decided to go full Synthetic, especially since my oil leak is fixed....

So i sprang for the Royal Purple, i've heard great things and so far its very good..

well zp uses it in there race cars...it works great...ive heard...only heard it tends to break down quicker then mobil one full synth, but its lubricating ability is supposed to be better..dont knwo why,
and horsepower tv dynoed and heat gunned the block and it gained 3hp and temps were about 10-15 cooler then some other synth ..i forgot which brand
so it hsould be fine...if not that i suggest getting mobil 1 most of us use it and are very happy with it..royal purple cost mroe,and most oil places dont carry it

i suggest the blazer 4.3 oil filter too,..holds more oil, and its a larger filter...ive been using it and no probs yet..cost the same
