read this before you decide on royal purple...

I use 10w 30 and rp is just as good as the rest. I like the long oil changes but not to long. 5k vs. 12k on the rp website. that guy on ls1.com ,sarge, is a dick. calm down it is just oil. I like rp

 

if oil is just oil then why the hell would spend that much money on a quart of oil...it's your money but until you can lay some facts out there like he has i'd prolly refrain from the name calling...

 

I have read alot of sarge stuff in the past, if you can get past, I know it's hard, his retarded attitude and the fact that he only calls people son cuz no woman in there right mind would allow his old cranky *** to father any, then he brings a **** load of real experience to the table. He usually will admit he's too over the top. Read the whole thread, great educational items in there if you believe good ole sarge.

 

thats a long *** thread there isnt much on royal purple there that i saw i personaly will not put pensoil in my truck

 

Me nether..... Some really good info in there if you dont mind sifting (sp) for it...

 

without reading it, what was the consensus?

 

I use RP and i actually gained 1.5 mpg and dropped 2 tenths off my 1/4 mile. I love the stuff
