Royal Purple Motor Oil

Ive been using this for a while now, and i have to say it's definitely worth it, i switched from Q Advanced High RPM to RP, both 10W30

I immediately noticed some changes:

the engine rev's much faster and smoother

It also idles smoother

i cant say that it adds HP because i don't have a dyno, but the car feels faster

the downside, this stuff if full synthetic, therefore it leaks like a siv, but on the upside, i now have purple stains on my driveway instead of black ones

over all, i would recommend this oil

:D I also reccomend it I used it in my neon and my truck never had any leaks and noticed all the things stated above.

my father added the Royal Purple radiator additive (purple Ice) with antifreeze. to his Ls6 454 powered Silverado, ran 20 degrees cooler on the hottest days of summer (truck runs hot and piston rattle going up hills in the summer on 93 octane. damn 16:1 compression :roll:)

Synth Oil

Post by Ghost Neon » Fri Aug 21, 2009 10:24 am

You do not have to run synthetic oil all the time, from my practice. It is thinner, to better lubricate the internals. Use it everything 3-5 oil rather than 100% of the time. Mix it in with regular engine oil. That is why it costs more, and leaks like a mo fo when that is all you use. That is also a sin you might want to replace seals and such. HTH.

Wow. This post has more fail than Eb04 (2GN and SRTForums reference)

Synthetic is not thinner.

Synthetic does not cause the leaks.

My car has had synthetic all its life, no leaks.

And the mouth returns.

Quote above where I said synthetic oil causes leaks. I'll save you the time. It is not there.

Using only synthetic can be done, but it not necessary. Again, I never said it cannot be done. Not sure what you drive, but it is pretty common to experience leak when switching to synthetic oil with older cars. Your one car is not the standard for everyone, but let's get some backround on this car. How long have you owned it? How many owners? How many miles on the engine?

most gaskets and seals on older cars are used to regular oil.
put synthetic in there and they start crying oil all over the place becuase synthetic IS thinner when gets hot.

dont believe me? heat up some regular oil and synthetic oil in seperate pots on a stove.

i say if you have a new engine with all new gaskets and seals, use it if you want. it will probly perform better. but probly delete some miles from your engines life.

I guess that bolded bit doesn't imply that synthetic causes leaks.

I drive a Neon. It has 85,000 miles on it and its always been my car.



Look at the numbers, cSt is the important number to look at when comparing thicknesses. Some oil in a pan doesn't mean anything.

The leaks after a switch to synthetic is caused by poor maintenance when it was on conventional.

Too many people know too many myths.

no myths involved. from my experience its not worth the money. it is a fact that when its hot it is thinner than regular oil. the thinner the oil the more likely it is to leak, and less barier between journals and bearings. for the cost of new seals and gaskets and expensive synthetic oil, you'd be better off just using regular oil. why make it complicated when it works when its simple.

So 5w20 has a better chance of leaking than 5w30?

Viscosity at 100* C (all values are in cSt and are for 5w30)
Castrol GTX - 10.8
Castrol Syntec - 9.7
Castrol Edge - 9.8
Mobil Clean 5000 - 10.6
Mobil 1 - 11.3
Mobil 1 Extended Performance - 11.0
Pennzoil (Yellow Bottle) - 10.5
Pennzoil Platnum - 10.3

And here's something that will fuck with your mind: Castrol Syntec 0w30 - 12.1

The range of viscosity for an oil to carry an xw30 rating is 9.3 - 12.5 cSt.

Leak:

intransitive verb

1 a : to enter or escape through an opening usually by a fault or mistake <fumes leak in> b : to let a substance or light in or out through an opening

transitive verb
1 : to permit to enter or escape through or as if through a leak

— leak·er \&#712;l&#275;-k&#601;r\ noun


You bet your sweet ass it does not. Old seals used with regular engine oil tend to experience leaks when switched to synthetic. Experienced this on 4 of my own cars and many others from friends and friends of friends. Seriously. It has to leak past something, in order to cause a leak. That something is the weak point, like you in this thread.
