I use Q Horsepower...not sure if it makes a difference though.

german castrol. its group 4 fully synthetic

I don't know with which one to go they all say the same thing "No leading conventional oil unleashes more horsepower"

i use mobile 1 fully synthetic. i know its a well known and good quality oil so i use it.

Its a bit misleading because conventional oil = non-synthetic.

Mobil 1!!!!!!!!!!

These Q oils are just retarded gimmicks.

There's nothing special about Mobil 1 anymore, hasn't been for several years...

German Castrol Syntec 0W-30 FTW. It's a real synthetic, unlike most other "synthetics" out there, and it's fairly cheap and readily available.

I recently switched from regular Mobil 1 to Mobil 1 Extended Performance and I can honestly say the car definitely feels smoother. I'll go as far as to say that I feel some lost hp has been restored. Supposedly Mobil 1 EP has 50% more synthetic properties than reg Mobil 1 and it has the ability to last 15k miles.

Why you say Royal Purple is bad for your engine? They show a lot of test where it shows how good the oil is. Does it have some minerals or somethig that in the long run damage your engine?

Here is a video testing Royal Purple

I know I'm going to get flamed for this, but there is absolutely no reason to use more expensive synthetic oil on a Sentra. Whether you're driving GXE, SE or Spec V, regular oil with the proper grade is all you need. I have used nothing but regular oil on all the cars I've owned and they all passed the 120K mile mark easily and never suffered engine failure.  My oil of choice is Castrol 5W-30.

I use Amsoil, I always heard good things about it, but Redline is also pretty good, I used Redline for a while.

jk, i get a discount on Royal Purple sometimes so why not go for it if it's gonna end up being the same price as something less expensive.

You're absolutely right, and this applies to at least 90% of the vehicles on the road. When serviced properly, an engine running conventional oil isn't going to last any less than an engine running synthetic oil. At least not that anyone's yet been able to prove to me.

Lots of people (Amsoil fanbois particularly) like to rag on Royal Purple because of its moly content, which they for some reason believe is bad for your engine. That's bullshit. The problem with Royal Purple is that it has like no shear stability, at all. What that means is that it thins out excessively compared to other oils and loses its viscosity. Obsidian's gearbox, an item that puts a lot of shear stress on oils, sped up this effect leading to the impairment of synchro function.

So, Royal Purple, no.

I just want to put a motor oil that will give a little performance but at the same time it will protect my engine. Does Qhorsepower will do these things?

i personally use Q advanced engine full sythetic but with that said Quacker state is all my family has used for many years its one of those dad things but anyways i put Royal Purple once and the onlything it did was it seemed to take longer to get oil pressure to come down to normal.. but its all opinion other than penzoil is horrible.. IMO

I change brand of oil so much it's not funny. I stuck with RP and Amsoil for a while.... Running 15W40 RP right now.

This hasn't been true for I don't even know how many years.

Remember i said " In My Own Opinon"

Well, what you said was, it's all opinion, EXCEPT that Pennzoil is horrible, "IMO." So you actually said both.

Call it opinion if you like but it's still wrong.
