Royal Purple

[Ruslik]

Is royal purple the best oil to run a turbo setup on??

[WarmAndSCSI]

No, it's purely a race oil that's meant to be changed after every race. I don't care if they say it's for street cars, it doesn't have the same additive package, that say, Mobil 1 or AMSOIL does for street usage.

This is correct. I had used Royal Purple when I started my car thinking it was the best, but Mobil 1 Synthetic is actually better and has cleaned up my engine a lot. I had lifter tap for God knows how long and even tried valve medic but Mobil 1 actually did something to the car and made it perform better aswell. Go for Mobil 1 dude

You guys do know that RP has a street oil out right.

Read my post. It's the opinion of many oil experts that their regular old street oil sold in parts stores still isn't sufficient for street usage. I was never impressed with it as well.

so mobil 1 synthetic?

[WarmAndSCSI]

No, it's actually not a real synthetic but it's good enough for you. The only real Mobil 1 synthetic in the US is 0W-40 cause it's BMW LL certified among other things that require it to be composed of at least Group IV base oils

AMSoil synthetic FTW!!

Meh, they have API certification which doesnt mean much, I mean penzoil got it. The initial film strenght is awesome but it gets dirty fast, thier additives also go away with few heat cycles.

I've heard mixed reactions to Royal Purple. Some say it's good some say it's not that good. I just stick to Quaker State Synthetic.

I'm still running regular mobile oil, maybe i should switch to Mobil 1 synthetic, do i just switch over completely? or is their a process

[silver_beast98]

if you really care enough, do the research... you will find that hands down, the best oil on the market is AMSOIL...

No, just switch. Most "switching to synthetic" horror stories are just isolated cases.

According to AMSOIL It's good stuff, but it's far from a godsend. Mobil 1 0W-40 is just as good.

For street usage Mobile 1 is probably the best oil you can use or Castrol GTX which had a little better results compared to Mobil 1 in a synthetic oil comparison I read last year.

No need to put any "hardcore race oil" if your car is 99% a street daily driver vehicle. With the money you save, buy a good oil filter like OEM or Puralator Pure One.

[WarmAndSCSI]

Castrol GTX is conventional oil... Syntec is their synthetic oil. They may have been reviewing German Castrol Syntec (0W-30) which is a very good real synthetic oil. Other Syntec is just like Mobil 1, it's not actually synthetic. They're allowed to call Group III-based motor oils "synthetic" in the United States. It does not matter any way unless you really run your engine hard.

i've used Mobil 1 synthetic for about a year; never had a problem using it

[IVORY_G]

I switched over to Mobil 1 Synthetic Oil about a year ago, and have been running it ever since. As of my last oil change I just started using the K&N Oil Filter also. I've had no complaints thus far. I've been running the 5W-30, but now I'm at about 75,000 miles, so I was gonna switch to 10W-40. Anybody think thats a bad idea?
I live in So Cali and drive about 275 miles a week. [City driving mind you, wish there was more wide open space out here.]
This AMSOIL, Ive never heard or seen it before, how much price difference is there b/w it and Mobil 1?

[WarmAndSCSI]

75,000 miles isn't nearly enough to start running a thicker oil. If anything, I'd use 0W-40 Mobil 1 just like I keep telling everybody.

AMSOIL is a ripoff for people who don't really race their cars, don't worry about it.

[IVORY_G]

Whats your reason for saying that 0W-40 is better? My mechanic is the one who suggested running thicker oil on my next change...

[WarmAndSCSI]

I really wish people just just start READING THE THREAD. 0W-40, like I said before, is better because it's an actual synthetic oil. It costs the same as other Mobil 1's and is a good viscosity choice in general. The 40 shears down to about a 30 and the 0W allows for better cold starts.
