if its such a good synthetic it should last longer than 3k

motor oil in general well last as long as you leave it in there. It doesnt mean it will do any good.

thats obvious im just saying even a mobil-1 is suppose to last 5-7k from what i hear, i know ive left in castrol syntec for 4500 and it wasnt broke down or to dirty, but a mobil 1 filter probably helped some which i dont usualy run

Re:: :: Royal Purple :: :
 

ive used mobil 1 and redline but didnt notice a difference between them both so i'd say go for the cheapest 1 ;)

i also heard that certain types of royal purple has to be run with gapless ringas. im not to sure what gapless rings mean, but i guess the oil is prety thin and gets passed the rings somehow unless there used

Re:: :: Royal Purple :: :
 

gapless rings I think are those total seal rings you can buy. Someone correct me if Im wrong.
