SakoTGrimes Posted May 17, 2005 Share Posted May 17, 2005 I have never used it personally but I see it advertised as "high performance" and the local rice burner shop sells it to the kids who like to rev the piss out of their Hondas.

86subaru Posted May 17, 2005 Share Posted May 17, 2005 yes i have heard about it ,i am using amsoil oil just about like it in my 88 dl d/r wagon with 187,000mi , 1 thing i have seen is that it will seep more even after all seals were replaced , royale purple claims better hp, mpg , .also aleast using amsoil it gave me 5-10 lbs more oil pressure , with a after market pressure gauge , Quote Link to comment Share on other sites More sharing options...
moshem74 Posted May 18, 2005 Author Share Posted May 18, 2005 so...what do you say? it worth ? it will make the engine work better? thank you? Quote Link to comment Share on other sites More sharing options...
86subaru Posted May 18, 2005 Share Posted May 18, 2005 i think it will ,the cost at first is higher but over a year it all comes out the same 5.95 ea x 4 = 23.80 , change oil every 12,000mi ,change filter every 6,000mi , and of course 1 extra qt for small leaks or burning , or regular oil at 1.79 qt every 3,000mi ,but i am only using amsoil oil right now , which is = to it , now for what grade 20-w50 or 15w -40 ? i guess it all depends on where you live ? hot all the time or pretty cool outside+ use a good filter , wix, ,bosh, mobile1, just my opinion Quote Link to comment Share on other sites More sharing options...
subie94 Posted May 18, 2005 Share Posted May 18, 2005 i've heard that their oil is supposed to actually increase hp output by decreasing friction.:-\ who knows? it might be true Quote Link to comment Share on other sites More sharing options...
86subaru Posted May 18, 2005 Share Posted May 18, 2005 yes i heard that to , also a guy with 3 company trucks that was at the store i was buying amsoil at said that his 3 v8 trucks were getting 2-3 mpg more using royale purple , i may try it myself , you can buy it for like 5.50 qt shipped or around that , Quote Link to comment Share on other sites More sharing options...
garner Posted May 19, 2005 Share Posted May 19, 2005 Royal Purple is awsome.... I won a free case from SubieSport magazine and I love it. Slight increase in mileage. I'd totally believe that it frees up some HP.. best thing is at the gas station, when the guy checks your oil and it's really fresh he says, "dude, your oil looks kind of purple" also, I go atleast 5-6k between changes with it so when you do the math, it's not that expensive... garner Quote Link to comment Share on other sites More sharing options...
