I'm wondering, with a fairly new motor...semi built...the stock k20a2 oil is 5w20...however ive been told that i should use 10w30 instead since im looking to push around 400whp on 14.5psi. what do you guys think?

How accurate was the build compared with factory tolerances? That the biggest issue on longevity... if completley within spec and machined properly.. id run royal purple 5w20..

ive heard royal purple is good stuff... someone recommended that i use natural oil instead of synthetic...however the motor parts im using are used exept for the pistons and rods and such that are going into it. i usually use Mobil 1 tho. didnt know if using the forged internals...would make a difference...+ the boost i know increases the heat.

Royal Purple versus Jiffy Oil versus ENEOS on a STOCK DPFI 1.5L Motor...draw your own conclusions on the actual quality of RP (puke).

we gained over 7 whp on our turbo engine with RP over 2 other brands... have you ran RP in setups over 500 whp? and on another note.. we had a setup that the oil pump gear shattered and we drove over 10 miles with no oil pressure and no bearings were scared. . results may vary of course.. do an experiment... take your new oil and mix it in a flask with water.. shake it up and let me know your results.. http://royalpurple.com/techrp/summary.html http://royalpurple.com/techa/whyrpa.html

nice

damn... well my man Tai Kahn at CorsportUSA has a direct supply with RP so ill definately get some.

dude i ship it daily. more you buy, cheaper it is.

the results that i got with royal purple 11 were good.i ganed 3.6 mph consistantlly over the break in 30wt oil.the motor is a bastard child b21 in my 90 prelude.

Xenocron: Any other oils tested?? Please tell more about your testing method. (multiple pulls for each oil? same day? time between pulls?)
