Royal Purple Synthetic or Castrol Edge Synthetic?

[Cb7Black9192]

Hey guys, Since I started driving and owning vehicles of my own I have always used Castrol Synthetic oils, It has never failed me and has always kept my engines running smoothly, my buddy told me the other day about this synthetic oil called "Royal Purple" which is supposed to be the top of the line product, has anyone ever used it before? is it better then castrol?

Honestly, unless your engine is built for high performance, you don't need any fancy oil to keep it properly lubricated. With our basic engines, a good synthetic will do no more than increase the amount of safe miles between oil changes.

Royal Purple is very good, by their reputation.
Castrol's German synthetic is very good (better than their US offerings, according to my STi-driving friend, who agonizes over his car's maintenance, and gets an oil analysis with every change... always good results in the analysis.)

I use Shell synthetic in my 09 Fit (10,000 miles between changes, driven hard, running for 10-15 hours straight, at least 5 days a week... currently at 268,000 miles.), my 06 CTS-V (96,000 miles running strong, though the first oil change since I bought it was done yesterday... I choose Shell over the factory suggested Mobil1.) and my CB7 with a 160,000 mile 1994 H22 in it (also never had problems.)

royal purple is good but if youre going to spend the money, go for amsoil.

I run Rotella T it's a great break in oil, high mileage oil, holds up good under a beating. It has a good % of ZDDP additives in the oil and it's cost friendly at just under $14 a gallon the only down side is cold start up's in the winters other than that IMO best bang for my buck.

I also use Mobile 1 full synthetic and on occasion amsoil, but it's costly.

im running royal purple after my break-in for my vw and i haven't changed it in a year hahaha. it's seen a lot of boost already.

probably switch it to amsoil before i store it for the winter.

I've heard it's good and when it first came out all the hot rod show's tested it and it performed good, but it's pricey i'll stick with my rotella.

As for amsoil i used that in my mirage and that car took one heck of a beating ever second of it's life although it's pretty expensive aswell i'd run amsoil over royal purple.

I use Pennzoil Platinum, i used to use Mobil 1 synthetic but i swore i could hear my valvetrain chattering in my Civic.

i used redline full synthetic in my impreza, never had issues for the 15000 miles or so between changes.

Pretty much every oil mentioned in this thread is far more than any F22A or H22A will need, unless you're booted, or running a serious N/A build. Or if you're like me, and you do 10,000 miles of hard driving between changes!

rotella for me, although it kinda bugs me i cant find 10w-30 in every store
most car 5w-30/15w40

Just make sure the oil is ACEA A3 rated then you are good.
