Mobil 1 vs. Royal Purple
 

I am coming up to my first oil change on my SS Cobalt, and I am debating between Mobil 1 and Royal Purple. Any opinions or suggestions?

Thanks,
Nick

Mobile 1, its has worked well for me.

Royal purple technically is a better oil...


but either one will do fine.

Why would you say Royal Purple is technically better??

Mobil one owns certain patents for additives that make Mobil One what it is and the only oil used and or covered for usage in its SC cars.


Royal Purple is like a coagulant, it clumps particles together, which is a good thing, so the filter can remove them, the bad part, filters clog faster. It was designed, TRUE ROYAL PURPLE as a race only oil, the street stuff without the coagulant properties is no better than the non Mobil One Syns.

i think there is an amazing thread about this, someone jsut search and youll find it it has really great information about both in it.

there is a dyno video on the royal purple site of them using the so called "street" stuff w/ the use of their transmission fluid on a camaro and it freed up 9hp at the wheels.

Also before anyon throws out some myths about it. I have asked the myth question at the royal purple site "If i use royal purple do i always have to use royal purple?" and they got back to me saying "No, that is a myth. You can switch back and forth with any oil you want at any time".

Just thought this info might help you in your choice

its more of a "once you switch to synthetic, you have to stay synthetic" thing....but since the ss has synth stock, thats not theissue

ive used both, and in my saturn i did notice a certain "free" feeling from the engine with royal purple. it just felt nice and smooth. the only oil i truly felt was better, but for my old saturn, was pennzoil/quaker state. with the use of royal purple and mobil 1, i burned oil. if i used quaker state, it didnt burn oil.

now in the cobalt, im running mobil 1. if i had the money, id run royal purple. but hell i get mobil 1 5 quart jug for less then $18. my next venture is with amsoil, but at $8-$10 a quart, i think ill wait for the hefty paycheck.

royal purple by far i reccomend or ams oil

it is all the same. i run walmart oil and my cars have 250K+ miles on them no problem. Hah, no wonder the oil companies make so much money, thanks to you folks trying to run so called racing oil in an economy car.

RP - Group 4
M1 - Group 3

There's your answer right there why it is better. RP goes in all of my cars.

You have to remember, they never told us what oil the Camaro had before. We don't even know if it was fully synthetic either. They could of been using regular motor oil and switched to Royal Purple. So of course they would of got a gain switching to fully syn. Honestly, IMO Mobil 1 is the way to go because that is what GM recomends...:twothumbs

There's a difference in oil requirements between the 2.2 and the 2.0 supercharged engine.

ROYAL PURPLE. I used Mobil 1 before i found about about Royal Purple. I did the research and RP is better overall.

Can Royal Purple say this?

Yea but the thing is how much did mobil 1 they pay to be able to get there name on those brands. The gm recomends it because mobil 1 paid enough money to get there name on the oil cap

screw mobil 1 and def dont use royal purple......i hate it with a passion...i work for a multi national company who for a few years decided to only run royal purple and now they are def paying for it with broke down vehicles.....AMSOIL-100%

mobil 1

Not one cent unlike Amsoil and other brands!!!!

:lol:

And Quaker State is recommended by ferrari for the F430 :lol:

RP is better. Been proven in so many tests.

I run rp in my ss/sc, and it runs really good after a oil change

i dunno if it's my thread ur talking about, but i did one about this a while ago, it has some really good info, i use royal purple it's good stuff, it is deffinately a better oil. it felt like it made a difference in the way of smoothness for my engine, just try it you wont hurt the engine, and dont believe the hype about anything other than Mobil 1 voiding ur warranty, it's all bullsh*t.

Anyone who says that anything but M1 will void the warranty is a moron and should be banned on the spot.

I just had my IRL in for a new belt since the last was slipping and i specifically told the tech i run RP and he agreed with me that it was the better oil. M1 is all a marketing gimmick. Old version of M1 was awesome but they changed it and it now sucks.

Actually I use amsoil and I think by far is the best oil out there. I used it for a total of
22k on my last car and it was a light brown both times I changed it . I got it for $80 dollars and that includes two 45 micron oil filter. The oil is good anywhere from 15000 to 25000 depending on your driving but I allways change it 12k cause that is the recomened oil filter change. I know you guys are going to call it BS but I haven't had a problem with it. My last balt was ss/sc and I changed the oil twice on it. She had about 29000 when she was stolen.

yep, you've got it all figured out
