Ive noticed at the GM dealers in the last year or so they have been carying both Mobil 1 as well as Castrol Edge ( Syntc ) . Both are full synthic. Did GM put Mobil 1 OR Castrol in the LNF's from the factory ? And , is Castrol Syntec okay to put in the LNF foe engine oil ? I assume it will do the job just fine and my car wont go boom ?

 

If I remember right, they are both GM approved oils. I forget what the certification is called though.

 

Ummm I know that Mobile1 is used by everyone and their mother but its sure as hell ain't the best out there. They are just the best at marketing their product the manufacturer's. Its been proven through testing that oils like Castrol Syntec are better than M1. Yes, there is an oil better than Castrol...... Amsoil. Surprisingly Pennzoil did OK. Royal purple is not as good as Penn. Mobile one didn't even make top 5 oils in the test.


Take samples of each and send it out to a lab. I bet you a hundred bucks(no joke) Amsoil will kickass in every way. I run Amsoil in the Opel and Castrol syntec in my DD beater(GLi)

ATP certification is what you mean.

 

im pretty sure u can use almost any synthetic oil, ive used both of those, they both are just fine

 

Castrol doesnt offer an oil that meets GM4718M, which is GMs synthetic oil standard, Edge only meets standard oil specs, I wouldnt put it in my LNF

 

I've been running castol edge since my first oil change due to reading a lot of reviews and lab results like 40rty was talking about. Mobil1 just never really impressed me all that much, and I definitely agree, amsoil is definitely a fantastic oil.

Castol for whatever reason now offers 2 versions of their edge line and as a result dropped their straight up syntec line. They now have edge with syntec power and edge with titanium. I'm pretty sure the titanium is basically the same thing as the original edge, and the edge with syntec is basically the same as the original castrol syntec. Not that it probably matters all that much, but I'm tired and I'm probably rambeling.... so there ya have it..

 

Son of a.. really? I thought I saw the gm standard on the bottle but I guess I'll have to check one of the bottles again when i get home

 

yeah I just looked on their site, Edge with Syntec is new name for Syntec. and it only meet 6094 performance specs, doesnt meet the better ones at all.

 

Well I'm confused. So Castro edge/syntec chairs better in tests. But it doesnt meet gms specs? So, is it safe to put it in our cars or not? I have ran it in the past in my lsj. But I really don't wanna run it if its gonna cause premature wear in engine because it doesn't lubracte properly. One reason I was thinking of using it is because wallmart has the 5L jugs on for $25. Great price. But not if its not safe to run in the lnf. As I side note. My local GM dealer will do an oil change on our cars with which EITHER oil and if anything happens engine wise under warranty. They say its totally covered.

 

Just because it may be better doesn't mean they tested it to GM specs. Everybody has their own requirements. Testing and certification is expensive and time consuming.

It won't hurt anything but if the oil did cause a problem and gm checked they could deny warranty because you didnt use the right stuff.

 

So really then it is in a persons best intrest to use Mobil 1 over Castrol syntec/edge ? I just wanna use whatever works well and wont screw me on the back end.

 

There is a whole list of oils that meet GM requirements. I haven't had Mobil 1 in my car since my 1st oil change. I'm not going to the dealer for it and the oil change place I go to doesn't have it.

 

What do you run in your lnf then ? Just curious ?

 

Pennzoil platinum

Here is an oil list from 2009.

 

Good info. It would be nice to see an updated list, but it looks like what I though about edge syntec and edge titanium is correct. Edge with syntec power is basically the same as what castrol syntec was before they discontinued the line, and edge titanium is the same as the orginal castrol edge (which does meet and exceed GM4718M standards btw). Unfortunately it doesn't look like the syntec line meets the same standards though, so like Maven said, I might think twice about using it in an lnf. The titanium however (which is what I use), is absolutely fine and is what tested so well in the lab results.

 

So IF i was to run a castrol product. I should look for Castrol Edge Titanium instead of just the plan Edge ? And , I have never seen Castrol Edge Titanium ?

 

That was the newest list i could find but i only looked for a minute. Still it covers most oils that probably plan on getting certified.

 

Im still not a fan of Castrol engine oil. I still really dont like how they only say it "meets performance requirements" with an asterisk.

Im running Mobil1 Extended performance, if I can pick up Redline somewhere and not have to pay shipping Ill be using that, beyond those too rather obvious choices, Quaker State Synthetic would probably be my second choice at WallyWorld, Id also run LiquiMoly stuff, and Shell Helix Ultra.

If youve got a warranty dont run something that isnt ACTUALLY 6094 or DEXOS1 licensed. Its not worth the risk.

 

I finally got a chance to look at the bottle and Castrol Edge Titanium actually meets the Dexos1 and GM6094M performance standards which actually exceeds the orginal Castrol Edge standards. Here's a good read for anyone interested in Castrol Edge Syntec and a couple other oils meeting or not meeting GM's Dexos1 standards. Castrol Will Not "Officially License" Edge and Syntec as dexos1™

I also obviously added pics I took off the Castrol Edge with Titanium standards on the bottle.

For the $1.50 for 5 quart jug savings, Id still rather have Mobil1EP or Pennzoil Ultra which are both licensed and tend to shear less than Castrol, if I was looking to save money Quakerstate Ultimate is $6 a jug cheaper. I see no reason for Castrol to be an option.

 

Lol.... wow, you feel pretty strongly about this one. I'm not defending one or the other here, I'm just posting in response to you comment of "dont run something that isnt ACTUALLY 6094 or DEXOS1 licensed. Its not worth the risk.", when in fact the oil meets both GM perfomance standards.

You just don't like thinking with your dipstick apparently!

 

LOL I actually hated those commercials.

I just dont see the point in having to worry about proving your oil actually meets the standards when there are plenty that actually do. I just dont see any benefit to choosing Castrol. I mean **** in the end, they are owned by BP and lotsa people hate BP

 

just stick with mobile1 .. it's what they recommend and the difference between oils is probably almost negligable. not worth the risk to save a few dollars IMO.

 

Now your talking out of your ass. I'm sorry but when it comes to your car being cheap about maintenance, thats negligable.
Do some research before giving "average joe" advice.
