Do you guys only use mobil one synthetic or? I was thinkin bout using the quaker state synthetic but im not to sure. thanks guys...

 

I use mobil 1 only, but then again I work for GM so I get it cheap.

 

mobil 1...lol just because the manual says so. If you have an internal problem and need to take it in for warranty work hopefully they wouldn't blame it on the oil but you never know

 

Theres a oil spec in the manual, its like 1394 or something like that for the minumum spec.
If its listed on the Quaker state I dont see a problem using it.
I will use the Can tire formula 1 synthetic ($19.00 for 4.4 liters )if mobil 1 not on sale, I am pretty sure its made by esso and meet all the specs listed in the manual.

 

i always use mobil one. i'm about to change my oil in a few! oil must have been on sale this week, oil AND filter for like 25 dollars!

 

royal purple 5W30 cant get much better than this, huge difference between mobil 1 and this stuff, RP makes a difference i swear!

 

I think Quaker State is re-used oil. I mean hell all oil is used but quaker is older. If that makes sence.

 

Who cares what the manual says.

RP - Group 4 Synthetic
Mobil 1 - Group 3

Group 4 > Group 3

 

you should care if you value your warranty...but I guess if you're ballin' like that maybe you don't

 

Using a better oil will not void your warranty. It is a minimum spec.

 

I use Mobil 1...because all my maintainence is done at he dealer so I can keep my free tires and batteries for life

 

It may not...however, my point was he said who cares what the manual says. My reply is if you don't care about the warranty than it doesn't matter what the manual says. But if you do just do what it says...simple

 

Your stealership does free tires for life as long as you get yer oil changes done there? Pretty sweet.

 

yea I have to get my oil changed and tires rotated every 6000 miles and I get free tires and batteries for life. But if I go over even by a mile they wont do it. They discontinued that offer so they are trying to get rid of everyone who has it, but as long as I keep my maintenence on time they cant void it.

 

You know that royal purple looks just like mobil 1 when it's drained correct?

 

if i recall correctly every oil i've seen commercial and military spec oils all look the same when drained... i've seen alot of oil... but hey i may be wrong, thats just what i've seen and i'm only one person.

 

Exactly so how will they know if you're using M1 or RP?

 

i know that every oil has it's own characteristics and what not, but i doubt they are gonna sit there and test it... or will they?!?! nah...

 

They won't. GM doesn't care if you use RP. They'll void your warranty for a CAI more then a specific oil.

RP is better then M1 so they don't care.

 

exactly... I LOVE RP, i bought a case and a filter... $118 i almost **** my pants, all i have to do is buy a filter next time though yesssssssssssssssssssssssss!

 

X2 it even acts as if it revs more freely. Royal Purple is the only way to go.

 

Just switched over to RP last week. Car feels nice through the revs now, and I certainly had it revving last weekend!
