Anyone use this? They claim 8X better protection then Mobile 1. Whats considered the best synthetic oil?

Royal Purple or AMSOIL

 

Redline oils used extensively for 7+ years.....but as always it's down to personal preference...

 

I use eneos but I know there was a big thread on what oil to use and who had bad experiences with what brands. I can't remember the link but it's on the forum some here. I would say if you want to try it try it, and if the engine doesn't like it change it out fast.

 

motul 300V tried other stuff but this one has been good for me so far.
i know a lot of bmw and audi/vw guys use this and heard some viper guys are starting to use this too.

 

I checked bobistheoilguy forum and I couldn't find anything bad about Castrol Edge other then that it is owned by BP and they are evil. There seems to be alot of arguments about weather Castrol Edge is any better the Mobil 1. Some people say that it does have better wear protection on the rocker arms of the motor.

 

Just changed from Castrol Syntec to Castrol edge 5w30. I plan on sending a sample after 3k.

My 2010 x has just a little over 6k miles. I was on stock oils til about 3k, then went to castrol syntec since that's what I had in my STI. When I went back to the Walmart for another 5quart jug, they were out and all I could find was the new Edge stuff. We'll see how it goes. From Bobistheoilguy I saw some posts that say this stuff might shear after 2k or so. Guess I'll help be a guinea pig.

 

i am in for the results,,, i have never seen a castrol oil lab sample, at least recently.

 

any updates about the castrol results?

 

oh man. Sorry. I collected the sample of the castrol edge after 3k miles but during that time i was moving into a new house. It was packed away. I'll have to email the oil analysis people to see if it will still be good. I've also gone back to Castrol Syntec since running edge so I cant take another sample.

 

what are the updates?
now that mobil 1 is watered down,
I need to find quick alternatives (off the shelf oils) that are good.

 

Holy old thread, but to add to input.
Run the Mobil 1 high mileage stuff, it the old formula with the SL rating with a high zinc count.

 

AMSoil SSO imho

 

LOL, i was still subscribed to this thread. I'm actually about 300 miles away from an oil change and I was going to do an oil analysis on the castrol. However.. i'm leaving for singapore for a month this saturday... wont be able to send out oil til june.
