Well its almost time for my first oil change and i was thinking of switching to royal purple. Is anybody using it? Should i go with royal or stay with factor oil????

I personnally like and recommend Mobil 1, but then again I am a dealer and have easy and cheap access to it.

i always used mobil 1. my brother used it in his cars and thats why i started using it. your not going to notice a difference between the two but i like mobil 1 just because thats what i have been using.

well right when i did my rp oil change, i loved it. i felt a lil more power honestly, smoother rpm range too. but now after 1500 miles, it feels more rough than before i got my oil changed. so from now on mobil one for me....i did the rp tranny fluid too. feels really good for the first 1500 miles.(did the tranny fluid 3 days b4 oil change)

Go with amsoil

I have been running royalpurple for about 6 oil changes and love it.
I would run either RP or Amsoil they both test alot higher that mobil 1

That's what I use... cheaper and better for your engine!

I have used royal purple in my last few cars. I changed oil on Sunday and added Z-max this time. Has anyone used it?

i've been using pennzoil platinum, and i like it better than mobil 1

Mobil 1 is a group 3 synthetic and royal purple is a FULL synthetic and a group 4.

Group 4 > Group 3

but you also have to change it more frequently.

Onyxd04Redline

No you don't. You can easily go 5K miles between oil changes. I do and i beat on my car daily.

ridemlow03

It doesnt hurt to go 5k miles but its always better to do it earlier. I do mine every 5k since synthetics are alot better. But another key thing people forget about is the oil filter itself. The better the oil filter the longer you have to go for oil changes. For example, Mercedes I believe you only have to change every 10-15k miles. They have better filters that filter the oil better which allows for better and longer lubrication.

I've been sold on Mobil 1 for quite some time now, but I've recently started using Royal Purple as an experiment in my Integra and in the Cobalt's transmission. Needless to say that I'm so impressed with Royal Purples products that my next oil change here will be Royal Purple in the Cobalt. Their GearMax tranny fluid I used in the Cobalt's transmission is phenominal. It always goes into gear so much smoother now and provides a shock protection to prevent damage to the all the components inside.

i have always said this "THERE IS A PURPOSE FOR GM USING MOBILE 1" so why not just stick with it my opinion

Onyxd04Redline

That purpose is to make Mobil one money.

KillerBee

Not really if GM recommends it for a certain engine why argue with them they get paid the good money to research and develope engines and what oil to use

Onyxd04Redline

There's no e in develop and it's all a marketing ploy. The new M1 formula blows.

Matty

I am sure GM gets a nice kickback for using Mobil. It is all politics. If the money wasn't right I am sure all of a sudden GM is using Penzoil or Royal Purple or some other name.

You can't go wrong using any of the big names, it all comes down to preference and warranty. JMO.

KillerBee

Well my uncle work for GM as a engine desinger and they use that oil if it says to on the cap that is what they use to test the engine with

Not really, just change your filter and then top off the oil. They say you can go 6000 miles on Mobil 1 or RP, just be sure to change your filter at the half way point. I personaly use RP and have been for years. Mobil 1 is good, but I like RP. I actually change my oil every 3000 miles despite what the oil life moniter says, and change my filter at the 1500 mile mark. My oil always stays clean and pretty. I live in one of the hotests citys in the country, and a very dusty one due to it being in the desert. To each his own though, I have seen this debate on this site far to many times. I would reccomend trying what I said, and you will be happy. But it is up to you, your the one that makes that car payment.

Also RP has been proven to make more power than M1 on the dyno, but it does not add power just frees up some by having syncerlic in it.
